上一篇文章：

Spring Security 4 Hibernate整合注解和xml例子（带源码）

下一篇文章：Spring Security 4 整合Hibernate 实现持久化登录验证（带源码）

原文地址：http://websystique.com/spring-security/spring-security-4-password-encoder-bcrypt-example-with-hibernate/

本教程演示使用 Spring Security 4中的BCryptPasswordEncoder对密码进行加密。

整合Spring MVC 4, Hibernate 4 & Spring Security 4，包含登录的权限验证和用户创建。

提供注解和XML两种配置方式。依赖的项目源码在文章末尾提供。

关于密码加密

任何应用考虑到安全，绝不能明文的方式保存密码。密码应该通过哈希算法进行加密。有很多标准的算法比如SHA或者MD5，结合salt(盐)是一个不错的选择。 Spring Security 提供了BCryptPasswordEncoder类,实现Spring的PasswordEncoder接口使用BCrypt强哈希方法来加密密码。

在应用中哪里可能用到密码加密?

1 在密码比对时。在和数据库存储的密码（已经加密过）进行进行比对前对输入的密码进行加密。

2 在创建新用户或者已经存在的用户密码修改时。在保存或者更新时，首先需要对输入的密码进行加密。

和前面文章的不同在哪里?

1. 创建和注入PasswordEncoder到 AuthenticationProvider 。在AuthenticationManagerBuilder中将其设置为验证提供者。

package com.websystique.springsecurity.configuration;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
 
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
 
    @Autowired
    @Qualifier("customUserDetailsService")
    UserDetailsService userDetailsService;
     
     
    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
        auth.authenticationProvider(authenticationProvider());
    }
     
     
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
     
     
    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
        authenticationProvider.setUserDetailsService(userDetailsService);
        authenticationProvider.setPasswordEncoder(passwordEncoder());
        return authenticationProvider;
    }
     
    @Override
    protected void configure(HttpSecurity http) throws Exception {
      http.authorizeRequests()
        .antMatchers("/", "/home").permitAll()
        .antMatchers("/admin/**","/newuser").access("hasRole('ADMIN')")
        .antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
        .and().formLogin().loginPage("/login")
        .usernameParameter("ssoId").passwordParameter("password")
        .and().csrf()
        .and().exceptionHandling().accessDeniedPage("/Access_Denied");
    }
}

通过上面的设置在应用中任何地方验证都将对密码进行比对。

上面配置对应的XML配置如下：

<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
    http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-4.0.xsd">
      
    <http auto-config="true" >
        <intercept-url pattern="/" access="permitAll" />
        <intercept-url pattern="/home" access="permitAll" />
        <intercept-url pattern="/admin**" access="hasRole('ADMIN')" />
        <intercept-url pattern="/dba**" access="hasRole('ADMIN') and hasRole('DBA')" />
        <form-login  login-page="/login"
                     username-parameter="ssoId"
                     password-parameter="password"
                     authentication-failure-url="/Access_Denied" />
        <csrf/>
    </http>
  
    <authentication-manager >
        <authentication-provider user-service-ref="customUserDetailsService">
            <password-encoder ref="bcryptEncoder"/>
        </authentication-provider>
    </authentication-manager>
      
    <beans:bean id="bcryptEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" />
 
    <beans:bean id="customUserDetailsService" class="com.websystique.springsecurity.service.CustomUserDetailsService" />
     
</beans:beans>

2. 更改 UserService 在新的密码存入数据库之前进行加密。

@Service("userService")
@Transactional
public class UserServiceImpl implements UserService{
 
    @Autowired
    private UserDao dao;
     
    @Autowired
    private PasswordEncoder passwordEncoder;
 
     
    public void save(User user){
        user.setPassword(passwordEncoder.encode(user.getPassword()));
        dao.save(user);
    }
     
    public User findById(int id) {
        return dao.findById(id);
    }
 
    public User findBySso(String sso) {
        return dao.findBySSO(sso);
    }
     
}

这就是通过Spring Security’s BCrypt实现密码加密的流程。

下面是完整的代码：

使用以下技术或者软件

Spring 4.1.6.RELEASE
Spring Security 4.0.1.RELEASE
Hibernate 4.3.6.Final
MySQL Server 5.6
Maven 3
JDK 1.7
Tomcat 8.0.21
Eclipse JUNO Service Release 2

让我们开始吧。

    </build>
</project>

数据库模式部分

---------------------------------------

第3步:创建数据库模式和填充模拟数据

/*All User's gets stored in APP_USER table*/
create table APP_USER (
   id BIGINT NOT NULL AUTO_INCREMENT,
   sso_id VARCHAR(30) NOT NULL,
   password VARCHAR(100) NOT NULL,
   first_name VARCHAR(30) NOT NULL,
   last_name  VARCHAR(30) NOT NULL,
   email VARCHAR(30) NOT NULL,
   state VARCHAR(30) NOT NULL,  
   PRIMARY KEY (id),
   UNIQUE (sso_id)
);
  
/* USER_PROFILE table contains all possible roles */ 
create table USER_PROFILE(
   id BIGINT NOT NULL AUTO_INCREMENT,
   type VARCHAR(30) NOT NULL,
   PRIMARY KEY (id),
   UNIQUE (type)
);
  
/* JOIN TABLE for MANY-TO-MANY relationship*/  
CREATE TABLE APP_USER_USER_PROFILE (
    user_id BIGINT NOT NULL,
    user_profile_id BIGINT NOT NULL,
    PRIMARY KEY (user_id, user_profile_id),
    CONSTRAINT FK_APP_USER FOREIGN KEY (user_id) REFERENCES APP_USER (id),
    CONSTRAINT FK_USER_PROFILE FOREIGN KEY (user_profile_id) REFERENCES USER_PROFILE (id)
);
 
/* Populate USER_PROFILE Table */
INSERT INTO USER_PROFILE(type)
VALUES ('USER');
 
INSERT INTO USER_PROFILE(type)
VALUES ('ADMIN');
 
INSERT INTO USER_PROFILE(type)
VALUES ('DBA');
 
 
/* Populate one Admin User which will further create other users for the application using GUI */
INSERT INTO APP_USER(sso_id, password, first_name, last_name, email, state)
VALUES ('sam','$2a$10$4eqIF5s/ewJwHK1p8lqlFOEm2QIA0S8g6./Lok.pQxqcxaBZYChRm', 'Sam','Smith','samy@xyz.com', 'Active');
 
 
/* Populate JOIN Table */
INSERT INTO APP_USER_USER_PROFILE (user_id, user_profile_id)
  SELECT user.id, profile.id FROM app_user user, user_profile profile
  where user.sso_id='sam' and profile.type='ADMIN';

注意：我们已经手动的插入了一个用户（我们需要一个Admin用户用来登录和创建应用中的其他用户）。

这是真实的场景。请关注密码部分。

这是使用下面提到的工具类（它甚至可能只是一个脚本）生成的，生成了一个管理员用户密码。

package com.websystique.springsecurity.util;
 
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
 
public class QuickPasswordEncodingGenerator {
 
    /**
     * @param args
     */
    public static void main(String[] args) {
            String password = "abc125";
            BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
            System.out.println(passwordEncoder.encode(password));
    }
 
}

上面程序产生了在上面数据库中使用的编码过的密码。

注意：同一个密码你运行时获取也会产生不同的值。因为BCrypt 哈希算法每次调用都产生不同的60位哈希值。

Security部分

-------------------------

第4步: 添加 Spring Security 配置类

package com.websystique.springsecurity.configuration;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
 
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
 
    @Autowired
    @Qualifier("customUserDetailsService")
    UserDetailsService userDetailsService;
     
     
    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
        auth.authenticationProvider(authenticationProvider());
    }
     
     
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
     
     
    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
        authenticationProvider.setUserDetailsService(userDetailsService);
        authenticationProvider.setPasswordEncoder(passwordEncoder());
        return authenticationProvider;
    }
     
    @Override
    protected void configure(HttpSecurity http) throws Exception {
      http.authorizeRequests()
        .antMatchers("/", "/home").permitAll()
        .antMatchers("/admin/**","/newuser").access("hasRole('ADMIN')")
        .antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
        .and().formLogin().loginPage("/login")
        .usernameParameter("ssoId").passwordParameter("password")
        .and().csrf()
        .and().exceptionHandling().accessDeniedPage("/Access_Denied");
    }
}

第5步: 注册springSecurityFilter

下面是定制初始化war包中的springSecurityFilter（第三步中的）注册类

package com.websystique.springsecurity.configuration;
 
import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;
 
public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
 
}

上面配置对应的xml配置如下：

<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
 
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

第 5步:定义 UserDetailsService 的实现

此service为Authentication Manager（验证管理器）提供验证详情。

package com.websystique.springsecurity.service;
 
import java.util.ArrayList;
import java.util.List;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import com.websystique.springsecurity.model.User;
import com.websystique.springsecurity.model.UserProfile;
 
@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService{
 
    @Autowired
    private UserService userService;
     
    @Transactional(readOnly=true)
    public UserDetails loadUserByUsername(String ssoId)
            throws UsernameNotFoundException {
        User user = userService.findBySso(ssoId);
        System.out.println("User : "+user);
        if(user==null){
            System.out.println("User not found");
            throw new UsernameNotFoundException("Username not found"); 
        }
            return new org.springframework.security.core.userdetails.User(user.getSsoId(), user.getPassword(), 
                 user.getState().equals("Active"), true, true, true, getGrantedAuthorities(user));
    }
 
     
    private List<GrantedAuthority> getGrantedAuthorities(User user){
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
         
        for(UserProfile userProfile : user.getUserProfiles()){
            System.out.println("UserProfile : "+userProfile);
            authorities.add(new SimpleGrantedAuthority("ROLE_"+userProfile.getType()));
        }
        System.out.print("authorities :"+authorities);
        return authorities;
    }
     
}

SpringMVC 部分

------------------------------------------------------

第7步: 添加 Controller（控制器）

package com.websystique.springsecurity.controller;
 
import java.util.List;
 
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.validation.Valid;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
import com.websystique.springsecurity.model.User;
import com.websystique.springsecurity.model.UserProfile;
import com.websystique.springsecurity.service.UserProfileService;
import com.websystique.springsecurity.service.UserService;
 
@Controller
public class HelloWorldController {
 
    @Autowired
    UserProfileService userProfileService;
     
    @Autowired
    UserService userService;
     
    @RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
    public String homePage(ModelMap model) {
        model.addAttribute("greeting", "Hi, Welcome to mysite");
        return "welcome";
    }
 
    @RequestMapping(value = "/admin", method = RequestMethod.GET)
    public String adminPage(ModelMap model) {
        model.addAttribute("user", getPrincipal());
        return "admin";
    }
 
    @RequestMapping(value = "/db", method = RequestMethod.GET)
    public String dbaPage(ModelMap model) {
        model.addAttribute("user", getPrincipal());
        return "dba";
    }
 
    @RequestMapping(value = "/Access_Denied", method = RequestMethod.GET)
    public String accessDeniedPage(ModelMap model) {
        model.addAttribute("user", getPrincipal());
        return "accessDenied";
    }
 
    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String loginPage() {
        return "login";
    }
 
    @RequestMapping(value="/logout", method = RequestMethod.GET)
    public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        if (auth != null){    
            new SecurityContextLogoutHandler().logout(request, response, auth);
        }
        return "redirect:/login?logout";
    }
 
     
    @RequestMapping(value = "/newUser", method = RequestMethod.GET)
    public String newRegistration(ModelMap model) {
        User user = new User();
        model.addAttribute("user", user);
        return "newuser";
    }
 
    /*
     * This method will be called on form submission, handling POST request It
     * also validates the user input
     */
    @RequestMapping(value = "/newUser", method = RequestMethod.POST)
    public String saveRegistration(@Valid User user,
            BindingResult result, ModelMap model) {
 
        if (result.hasErrors()) {
            System.out.println("There are errors");
            return "newuser";
        }
        userService.save(user);
         
        System.out.println("First Name : "+user.getFirstName());
        System.out.println("Last Name : "+user.getLastName());
        System.out.println("SSO ID : "+user.getSsoId());
        System.out.println("Password : "+user.getPassword());
        System.out.println("Email : "+user.getEmail());
        System.out.println("Checking UsrProfiles....");
        if(user.getUserProfiles()!=null){
            for(UserProfile profile : user.getUserProfiles()){
                System.out.println("Profile : "+ profile.getType());
            }
        }
         
        model.addAttribute("success", "User " + user.getFirstName() + " has been registered successfully");
        return "registrationsuccess";
    }
 
     
     
     
    private String getPrincipal(){
        String userName = null;
        Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
 
        if (principal instanceof UserDetails) {
            userName = ((UserDetails)principal).getUsername();
        } else {
            userName = principal.toString();
        }
        return userName;
    }
     
     
     
    @ModelAttribute("roles")
    public List<UserProfile> initializeProfiles() {
        return userProfileService.findAll();
    }
 
}

第8步: 添加 SpringMVC 配置类

package com.websystique.springsecurity.configuration;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.format.FormatterRegistry;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
 
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springsecurity")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
     
    @Autowired
    RoleToUserProfileConverter roleToUserProfileConverter;
     
     
    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");
        registry.viewResolver(viewResolver);
    }
     
    /*
     * Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
     *
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    }
     
    /*
     * Configure Converter to be used.
     * In our example, we need a converter to convert string values[Roles] to UserProfiles in newUser.jsp
     */
    @Override
    public void addFormatters(FormatterRegistry registry) {
        registry.addConverter(roleToUserProfileConverter);
    }
     
     
}

在此类中唯一有兴趣的是注册可以负责通过id转换为对象的转换器。

这需要在jsp中处理1对多的关系。

在用户创建时，一个用户可以分配多个角色或者用户配置文件（roles/userProfiles），因此我们需要一个转换器，它能够根据id来建立特定的角色和用户配置之间的map。下面提供的就是这个转换类。

---------译者增加 start---明明如月--------
以上配置对应的xml配置如下

 <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
    <mvc:resources mapping="<span style="font-family: 'Open Sans', sans-serif;">/static/**</span>" location="<span style="font-family: 'Open Sans', sans-serif;">/static/</span>" />
    
   <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />
        <beans:property name="suffix" value=".jsp" />
    </beans:bean>

<mvc:annotation-driven conversion-service="conversionService"/>
 
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
 
    <property name="converters">
        <list>
            <bean id="roleToUserProfile" class="com.websystique.springsecurity.configuration.RoleToUserProfileConverter" />
        </list>
    </property>
</bean>

第9步: 添加Initializer（初始化器）类

package com.websystique.springsecurity.configuration;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.convert.converter.Converter;
import org.springframework.stereotype.Component;
 
import com.websystique.springsecurity.model.UserProfile;
import com.websystique.springsecurity.service.UserProfileService;
 
@Component
public class RoleToUserProfileConverter implements Converter<Object, UserProfile>{
 
    @Autowired
    UserProfileService userProfileService;
 
    /*
     * Gets UserProfile by Id
     * @see org.springframework.core.convert.converter.Converter#convert(java.lang.Object)
     */
    public UserProfile convert(Object element) {
        Integer id = Integer.parseInt((String)element);
        UserProfile profile= userProfileService.findById(id);
        System.out.println("Profile : "+profile);
        return profile;
    }
     
    /*
     * Gets UserProfile by type
     * @see org.springframework.core.convert.converter.Converter#convert(java.lang.Object)
     */
    /*
    public UserProfile convert(Object element) {
        String type = (String)element;
        UserProfile profile= userProfileService.findByType(type);
        System.out.println("Profile ... : "+profile);
        return profile;
    }
    */
 
}

第10步: 添加Initializer（初始化器）类

package com.websystique.springsecurity.configuration;
 
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
 
public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
 
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { HelloWorldConfiguration.class };
    }
  
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }
  
    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
 
}

Hibernate 配置部分

----------------------

第11步: 添加 Controller（控制器）

hibernate配置类添加@Bean对DataSource配置的方法以及SessionFactory & Transaction Manager上。

数据源属性从application.properties文件获取，其中也包含连接MySQL 数据库的链接等。

package com.websystique.springsecurity.configuration;
 
import java.util.Properties;
 
import javax.sql.DataSource;
 
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
 
@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.websystique.springsecurity.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {
 
    @Autowired
    private Environment environment;
 
    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "com.websystique.springsecurity.model" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }
     
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }
     
    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        return properties;        
    }
     
    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory s) {
       HibernateTransactionManager txManager = new HibernateTransactionManager();
       txManager.setSessionFactory(s);
       return txManager;
    }
}

application.properties

jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/websystique
jdbc.username = myuser
jdbc.password = mypassword
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true

DAO, Model & Service部分

-------------------------------------------------------------------------

第12步:创建 Model（模型）类

一个用户可以有多种角色[DBA,ADMIN,USER]，一个角色也可以被分配给多个用户。

因此在UserProfile[role] 和User之间，这里有Many-To-Many 关系映射。

我们保持的是单向映射即[User 对UserProfile]，

因为我们主要关心通过给定的用户查找角色。

package com.websystique.springsecurity.model;

        return this.state;
    }
 
 
    public String getName(){
        return this.name();
    }
 
 
}

第13步:创建Dao层

package com.websystique.springsecurity.dao;
 
import java.io.Serializable;
 
import java.lang.reflect.ParameterizedType;
 
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
 
public abstract class AbstractDao<PK extends Serializable, T> {
     
    private final Class<T> persistentClass;
     
    @SuppressWarnings("unchecked")
    public AbstractDao(){
        this.persistentClass =(Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass()).getActualTypeArguments()[1];
    }
     
    @Autowired
    private SessionFactory sessionFactory;
 
    protected Session getSession(){
        return sessionFactory.getCurrentSession();
    }
 
    @SuppressWarnings("unchecked")
    public T getByKey(PK key) {
        return (T) getSession().get(persistentClass, key);
    }
 
    public void persist(T entity) {
        getSession().persist(entity);
    }
 
    public void delete(T entity) {
        getSession().delete(entity);
    }
     
    protected Criteria createEntityCriteria(){
        return getSession().createCriteria(persistentClass);
    }
 
     
}

package com.websystique.springsecurity.dao;
 
import com.websystique.springsecurity.model.User;
 
public interface UserDao {
 
    void save(User user);
     
    User findById(int id);
     
    User findBySSO(String sso);
     
}

package com.websystique.springsecurity.dao;
 
import org.hibernate.Criteria;
import org.hibernate.criterion.Restrictions;

        persist(user);
    }
     
    public User findById(int id) {
        return getByKey(id);
    }
 
    public User findBySSO(String sso) {
        Criteria crit = createEntityCriteria();
        crit.add(Restrictions.eq("ssoId", sso));
        return (User) crit.uniqueResult();
    }
 
}

package com.websystique.springsecurity.dao;
 
import java.util.List;
 
import com.websystique.springsecurity.model.UserProfile;
 
public interface UserProfileDao {
 
    List<UserProfile> findAll();
     
    UserProfile findByType(String type);
     
    UserProfile findById(int id);
}

package com.websystique.springsecurity.dao;

        Criteria crit = createEntityCriteria();
        crit.addOrder(Order.asc("type"));
        return (List<UserProfile>)crit.list();
    }
     
    public UserProfile findById(int id) {
        return getByKey(id);
    }
     
    public UserProfile findByType(String type) {
        Criteria crit = createEntityCriteria();
        crit.add(Restrictions.eq("type", type));
        return (UserProfile) crit.uniqueResult();
    }
}

第14步: 创建 Service层

package com.websystique.springsecurity.service;
 
import java.util.List;
 
import com.websystique.springsecurity.model.UserProfile;
 
public interface UserProfileService {
 
    List<UserProfile> findAll();
     
    UserProfile findByType(String type);
     
    UserProfile findById(int id);
}

package com.websystique.springsecurity.service;
 
import java.util.List;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import com.websystique.springsecurity.dao.UserProfileDao;
import com.websystique.springsecurity.model.UserProfile;
 
@Service("userProfileService")
@Transactional
public class UserProfileServiceImpl implements UserProfileService{
     
    @Autowired
    UserProfileDao dao;
     
    public List<UserProfile> findAll() {
        return dao.findAll();
    }
 
    public UserProfile findByType(String type){
        return dao.findByType(type);
    }
 
    public UserProfile findById(int id) {
        return dao.findById(id);
    }
}

package com.websystique.springsecurity.service;
 
import com.websystique.springsecurity.model.User;
 
public interface UserService {
 
    void save(User user);
     
    User findById(int id);
     
    User findBySso(String sso);
     
}

package com.websystique.springsecurity.service;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
 
import com.websystique.springsecurity.dao.UserDao;
import com.websystique.springsecurity.model.User;
 
@Service("userService")
@Transactional
public class UserServiceImpl implements UserService{
 
    @Autowired
    private UserDao dao;
     
    @Autowired
    private PasswordEncoder passwordEncoder;
 
     
    public void save(User user){
        user.setPassword(passwordEncoder.encode(user.getPassword()));
        dao.save(user);
    }
     
    public User findById(int id) {
        return dao.findById(id);
    }
 
    public User findBySso(String sso) {
        return dao.findBySSO(sso);
    }
     
}

Views（视图）部分

--------------------------------

第15步: 添加Views

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

        <link href="<c:url value='/static/css/app.css' />" rel="stylesheet"></link>
        <link rel="stylesheet" type="text/css" href="//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.2.0/css/font-awesome.css" />
    </head>
 
    <body>
        <div id="mainWrapper">
            <div class="login-container">
                <div class="login-card">

                        <c:url var="loginUrl" value="/login" />
                        <form action="${loginUrl}" method="post" class="form-horizontal">
                            <c:if test="${param.error != null}">

                            </c:if>
                            <c:if test="${param.logout != null}">
                                <div class="alert alert-success">

                                </div>
                            </c:if>
                            <div class="input-group input-sm">
                                <label class="input-group-addon" for="username"><i class="fa fa-user"></i></label>
                                <input type="text" class="form-control" id="username" name="ssoId" placeholder="Enter Username" required>
                            </div>
                            <div class="input-group input-sm">
                                <label class="input-group-addon" for="password"><i class="fa fa-lock"></i></label> 
                                <input type="password" class="form-control" id="password" name="password" placeholder="Enter Password" required>
                            </div>
                            <input type="hidden" name="${_csrf.parameterName}"
                                value="${_csrf.token}" />
                                 
                            <div class="form-actions">
                                <input type="submit"
                                    class="btn btn-block btn-primary btn-default" value="Log in">
                            </div>
                        </form>
                    </div>
                </div>
            </div>
        </div>
 
    </body>
</html>

注意：和CSRF 相关的是

<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" /></strong>

这一行的目的是防止CSRF攻击。正如你所见jsp中CSRF参数使用EL表达式获取的。因此需要允许el表达式：

需要在jsp头添加如下一行：

<%@ page isELIgnored="false"%>

第16步:构建和部署应用

现在构建 war 包(通过eclipse或者myeclipse)或者通过maven 命令行( mvn
 clean install). 在一个 Servlet 3.0 容器中发布本应用. 在这里我使用的是tomcat, 我将 war 文件放到 tomcat
 webapps 文件夹然后点击 tomcat安装目录的bin文件夹下的start.bat .

启动应用
打开浏览器在地址栏输入localhost:8080/SpringSecurityPasswordEncodingWithBcryptExample/并回车
