标签:spring security   国际化   security3.2   权限控制   

前言

        本来是打算在上一篇SpringMVC+Hibernate上写的,结果发现上面那篇一起整合的,结果发现上一篇内容实在是太长了,就另起一篇,这篇主要是采用 Maven搭建Spring+SpringMVC+Hibernate+Security整合,而Spring+SpringMVC+Hibernate已经在上一篇介绍了,在这篇将不再重复写了,主要说明一下SpringSecurity3.2权限控制整合搭建,以及配置,使用注意事项等。

        SpringSecurity的Api文档地址:查看

1、Maven映入SpringSecurity依赖包

      在pom.xml中引入我们需要引入spring-security-core,spring-security-config,spring-security-taglibs三个包,如下

    

               <!-- spring-security -->
		<dependency>
			<groupId>org.springframework.security</groupId>
			<artifactId>spring-security-core</artifactId>
			<version>${security.version}</version>
		</dependency>

		<dependency>
			<groupId>org.springframework.security</groupId>
			<artifactId>spring-security-config</artifactId>
			<version>${security.version}</version>
		</dependency>

		<dependency>
			<groupId>org.springframework.security</groupId>
			<artifactId>spring-security-taglibs</artifactId>
			<version>${security.version}</version>
		</dependency>

2、配置security的配置文件

      我们新建一个配置文件(起名随意),我这儿就叫spring-security.xml,我现在定义了几个权限,权限信息表内容如下:

     技术分享

  其中:管理用户和全部用户的权限将通过jsp中security标签配置,其他的通过spring-security.xml文件配置。

  先贴出spring-security.xml的文件,详细配置含义我将做一个简单的说明:

    

<span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:security="http://www.springframework.org/schema/security"
	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-3.2.xsd"
	default-lazy-init="true">

	<description>spring-security配置</description>

	<!-- 静态资源 -->
	<security:http pattern="/css/**" security="none" />
	<security:http pattern="/js/**" security="none" />
	<security:http pattern="/images/**" security="none" />

	<security:http>
		<security:intercept-url pattern="/user/save*"
			access="ROLE_添加用户" requires-channel="any" />
		<security:intercept-url pattern="/user/delete*"
			access="ROLE_删除用户" requires-channel="any" />
		<security:intercept-url pattern="/user/user*"
			access="ROLE_浏览用户" requires-channel="any" />
		<security:intercept-url pattern="/user/update*"
			access="ROLE_修改用户" requires-channel="any" />

		<security:session-management>
			<security:concurrency-control
				expired-url="/login/login.htmls?repeat=true" max-sessions="1"
				error-if-maximum-exceeded="true" />
		</security:session-management>

		<security:form-login login-page="/login/login.htmls"
			authentication-failure-url="/login/login.htmls?error=true"
			default-target-url="/user/main.htmls" always-use-default-target='true'
			username-parameter="nickName" password-parameter="nickPassword" />

		<security:logout invalidate-session="true"
			logout-success-url="/login/login.htmls?logout=true" />

	</security:http>

	<!-- 认证配置 自定义认证实现UserDetailsService接口 -->
	<security:authentication-manager>
		<security:authentication-provider
			user-service-ref="userDetailsService">
			<!-- 配置密码加密方式 -->
			<security:password-encoder hash="md5" />
		</security:authentication-provider>
	</security:authentication-manager>

	<bean id="userDetailsService" class="org.andy.work.service.impl.UserDetailsServiceImpl" />
	
</beans></span>

  其中:我们配置了静态文件管理,session对话管理,登录管理,注销配置,权限配置,自定义数据表权限认证配置。

2.1、静态文件管理

    我们对于css,image,js这些不用权限拦截。

2.2、session对话管理

   session管理max-sessions="1"配置了最多有一个用户登录,(在wab.xml还要添加如下:)

         

<span style="font-size:14px;"><!-- spring-security 管理session配置 -->
	<listener>
		<listener-class>
			org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
	</listener></span>

    error-if-maximum-exceeded="true"  值为true时,若果有一个用户登录,第二个用户无法登陆,

                                                                  值为false时,若果有一个用户已经登录,下一个用户登录将踢掉上一个用户。

    自然在session-manager中我们可以配置session失效时,跳转的url如,invalid-session-url="/invalidSession.jsp",如果session失效时,刷新将跳转到invalidSession.jsp页面。

2.3、登录管理

    通过security:form-login配置登录,login-page为登录跳转的url,authentication-failure-url为登录失败时的url(次url可以不存在),

   username-parameter和password-parameter为登录表单是用户名和密码,如果不写默认为j_password和j_username

   login-processing-url:为登录时表单action跳转的url,如果不填写默认为 j_spring_security_check。

2.4、注销管理

   通过security:logout标签配置注销,invalidate-session:注销时session是否失效。logout-success-url:注销成功后跳转的地址。

logout-url:为注销的url,如果不填写,则默认为j_spring_security_logout

2.5、权限配置

   security:intercept-url为要拦截权限认证的的url,pattern为拦截的正则匹配url,access:所需的权限,可以是一个权限组,用逗号隔开,requires-channel:拦截http还是https的,如果两个都拦截用any。

2.6、配置自定义的权限认证机制

    通过我们数据库的权限表信息,我们自定义权限认证机制,需要我们实现UserDetailsService接口,配置用户密码的加密方式。

security:password-encoder:配置密码加密规则。

3、web.xml容器配置

   

<span style="font-size:14px;">         <context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			classpath:spring.xml
		    classpath:spring-hibernate.xml
			classpath:spring-security.xml
		</param-value>
	</context-param>

       <!-- Spring-Security filter 最好配置在控制层filter的前面 -->
	<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>

	<!-- spring-security 管理session配置 -->
	<listener>
		<listener-class>
			org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
	</listener></span>
 

配置了加载的spring-security文件,security拦截的filter,以及security的session监听。

4、自定义认证,实现UserDetailsService接口

UserDetailsServiceImpl如下:

<span style="font-size:14px;">package org.andy.work.service.impl;

import java.util.HashSet;
import java.util.Set;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctAuthority;
import org.andy.work.entity.AcctRole;
import org.andy.work.entity.AcctUser;
import org.apache.log4j.Logger;
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.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;

/**
 * 创建时间:2015-2-9 下午5:24:44
 * 
 * @author andy
 * @version 2.2
 *          <p>
 *          描述: 实现SpringSecurity的UserDetails接口 自定义认证
 */

public class UserDetailsServiceImpl implements UserDetailsService {

	private static final Logger LOGGER = Logger
			.getLogger(UserDetailsServiceImpl.class);

	// 注入查询User的dao层
	@Autowired
	private UserDao userDao;

	@Override
	public UserDetails loadUserByUsername(String username)
			throws UsernameNotFoundException {
		LOGGER.info("认证用户:" + username);

		// 查询数据库获取改用户的信息
		AcctUser acctUser = userDao.findByNickName(username);

		if (null == acctUser) {
			throw new UsernameNotFoundException("用户:" + username + "不存在");
		}

		Set<GrantedAuthority> authorities = getAuthorities(acctUser);

		// 将没有使用到的属性设置为true
		UserDetails userDetails = new User(acctUser.getNickName(),
				acctUser.getNickPassword(), true, true, true, true, authorities);

		return userDetails;
	}

	// 获得用户所有角色的权限
	private Set<GrantedAuthority> getAuthorities(AcctUser acctUser) {
		Set<GrantedAuthority> authoritySet = new HashSet<GrantedAuthority>();

		// 默认所有的用户有"浏览用户"的权利
		authoritySet.add(new SimpleGrantedAuthority("ROLE_浏览用户"));

		// 依次添加
		if (null != acctUser.getAcctRoles()
				&& acctUser.getAcctRoles().size() > 0)
			for (AcctRole role : acctUser.getAcctRoles()) {
				if (null != role.getAcctAuthorities()
						&& role.getAcctAuthorities().size() > 0)
					for (AcctAuthority authority : role.getAcctAuthorities()) {
						authoritySet.add(new SimpleGrantedAuthority(authority
								.getPrefixedName()));
					}
			}

		return authoritySet;
	}

}
</span>

涉及到的AcctUser,AcctRole,AcctAuthority类我就不贴了,不然一大把,我会提供源码。

5、Security的认证错误提示

    我们可以通过sessionScope.SPRING_SECURITY_LAST_EXCEPTION.message获取认证错误。

6、Security获取session中的用户名和用户信息

     security将用户信息存放在session中,可以通过以下两种获得:

6.1、后台获取

    

<span style="font-size:14px;">		//获取security的上下文
		SecurityContext securityContext = SecurityContextHolder.getContext();
		//获取认证对象
		Authentication authentication = securityContext.getAuthentication();
		//在认证对象中获取主体对象
		Object principal = authentication.getPrincipal();
		
		String username = "";
		if(principal instanceof UserDetails){
			username = ((UserDetails) principal).getUsername();
		}else {
			username = principal.toString();
		}</span>

6.1、前台获取

    先引入security的标签库:

<span style="font-size:14px;"><%@taglib prefix="security" uri="http://www.springframework.org/security/tags"%></span>

在查看:
<span style="font-size:14px;"><security:authentication property="name"/></span>

7、前台标签授权

    通过security:authorize标签设置权限,其有三种属性分别如下:

        ifAnyGranted::只有当前用户拥有所指定的权限中的一个的时候,就能显示标签内部的内容(相当于“或”的关系)

          ifAllGranted:只有当前用户拥有所指定的权限时,才显示标签的内容(相当于“与”的关系)

          ifNotGranted:  没有指定的权限的时候,显示标签内容(相当于“非”的关系

自然也可以通过method限制是那种http的请求(http的请求有8种:- GET - DELETE - HEAD - OPTIONS    - POST     - PUT    - PATCH    - TRACE)。

8、后台Controller

LoginController

<span style="font-size:14px;"><span style="font-size:14px;">package org.andy.work.controller;

import org.andy.work.entity.AcctUser;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.validation.Errors;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

/**
 * 创建时间:2015-2-10 下午9:23:34
 * 
 * @author andy
 * @version 2.2 描述:
 */
@Controller
@RequestMapping("/login")
public class LoginController {

	private static final Logger LOGGER = Logger
			.getLogger(LoginController.class);

	@RequestMapping("/login")
	public String login(@ModelAttribute AcctUser acctUser,
			@RequestParam(required = false) Boolean logout,
			Errors errors
			) {
		LOGGER.info("login");
		
		if(null != logout){
			errors.reject("msg", "已经安全退出");
		}
		
		return "/login/login";
	}


}</span>
</span>

UserController类 
<span style="font-size:14px;">package org.andy.work.controller;

import java.util.List;

import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**  
 * 创建时间:2015-2-7 上午11:49:00  
 * @author andy  
 * @version 2.2  
 * 描述: 用户Controller
 */
@Controller
@RequestMapping("/user")
public class UserController {

	private static final Logger LOGGER = Logger.getLogger(UserController.class);
	
	@Autowired
	private UserService userService;
	
	@RequestMapping("/showInfo/{userId}")
	public String showUserInfo(ModelMap modelMap, @PathVariable String userId){
		LOGGER.info("查询用户:" + userId);
		AcctUser userInfo = userService.load(userId);
		modelMap.addAttribute("userInfo", userInfo);
		return "/user/showInfo";
	}
	
	@RequestMapping("/showInfos")
	public @ResponseBody List<AcctUser> showUserInfos(){
		LOGGER.info("查询用户全部用户");
		List<AcctUser> userInfos = userService.findAll();
		return userInfos;
	}
	
	
	@RequestMapping("/main")
	public String main(ModelMap modelMap){
		LOGGER.info("显示主页面");
		//后台获取security保存的session中的用户信息
		
		//获取security的上下文
		SecurityContext securityContext = SecurityContextHolder.getContext();
		//获取认证对象
		Authentication authentication = securityContext.getAuthentication();
		//在认证对象中获取主体对象
		Object principal = authentication.getPrincipal();
		
		String username = "";
		if(principal instanceof UserDetails){
			username = ((UserDetails) principal).getUsername();
		}else {
			username = principal.toString();
		}
		modelMap.addAttribute("username", username);
		return "/user/main";
	}
	
	
	@RequestMapping("/manage")
	public String manage(ModelMap modelMap){
		LOGGER.info("显示主页面");
		modelMap.addAttribute("msg", "manage");
		return "/user/option";
	}
	
	@RequestMapping("/save")
	public String save(ModelMap modelMap){
		LOGGER.info("保存");
		modelMap.addAttribute("msg", "save");
		return "/user/option";
	}
	
	@RequestMapping("/update")
	public String update(ModelMap modelMap){
		LOGGER.info("修改");
		modelMap.addAttribute("msg", "update");
		return "/user/option";
	}
	
	@RequestMapping("/delete")
	public String delete(ModelMap modelMap){
		LOGGER.info("删除");
		modelMap.addAttribute("msg", "delete");
		return "/user/option";
	}
	
}
</span>

 9、前台

10、测试

    现在andy用户拥有“浏览用户”和“添加用户”权限

用户密码错误时:

  正确密码登陆后:

     

     技术分享

点击添加用户,正确跳转。如下:


技术分享


点击全部用户,无权限提示。

11、Spring security自定义认证错误提示

    首先,拷贝spring-security-core写的messages_zh_CN.properties国际化文件,放到项目的src/main/resources目录中

          修改对应的提示,按照我们自己的需求,我命名为messages.properties

   其次, 我们需在spring的配置文件中添加如下内容:

<span style="font-size:14px;"><span style="font-size:14px;">	<!-- 定义上下文返回的消息的国际化 -->
	<bean id="messageSource"
		class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
		<property name="basename" value="classpath:messages" />
	</bean>

	<bean id="localeResolver"
		class="org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver" /></span></span>

ok,Maven搭建Spring+Hibernate+security整合完毕。


后续

遗留问题,通用的重写security提示信息,其他的都能国际化汉语提示,但是

唯独

ConcurrentSessionControlStrategy.exceededAllowed=\u5DF2\u7ECF\u6709 {0} \u4E2A\u7528\u6237\u767B\u5F55\uFF0C\u4E0D\u80FD\u91CD\u590D\u767B\u5F55

我修改重复登录提示时,还是security原来自带的提示,如下:
