搭建一个基于maven的web工程
在web.xml配置文件中写上如下代码

编写一个类SpringSecurityUserService，实现UserDetailsService接口并重写方法，框架会自动帮我们调用这个方法，username就是前端登录的用户名，但是框架怎样就能自动帮我们调用一个我们自己写的方法呢，所以，我们需要配置一下
public class SpringSecurityUserService implements UserDetailsService {
@java.lang.Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
//这个方法框架帮我们调用，username是登录传进来的，但我们要配置这个类。
System.out.println("输入的用户名是"+username);
return null;
}
}
<security:authentication-manager>
<!--配置认证提供者-->
<security:authentication-provider user-service-ref="userService">
<!--<security:user-service >-->
<!--<security:user name="admin" password="{noop}1234" authorities="ROLE_ADMIN"></security:user>-->
<!--</security:user-service>-->
</security:authentication-provider>
</security:authentication-manager>
<bean id="userService" class="com.itheima.service.SpringSecurityUserService"></bean>
2个地方，第一个，需要配置<bean id="userService" class="com.itheima.service.SpringSecurityUserService"></bean>,
第二个，需要引用这个对象。
package com.itheima.service;
import com.itheima.pojo.User;
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 java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class SpringSecurityUserService implements UserDetailsService {
//模拟数据库中的用户数据
public static Map<String, User> map = new HashMap<>();
static {
com.itheima.pojo.User user1 = new com.itheima.pojo.User();
user1.setUsername("admin");
user1.setPassword("admin");//明文密码（没有加密）
com.itheima.pojo.User user2 = new com.itheima.pojo.User();
user2.setUsername("xiaoming");
user2.setPassword("1234");
map.put(user1.getUsername(),user1);
map.put(user2.getUsername(),user2);
}
//根据用户名查询用户信息
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
System.out.println("用户输入的用户名为：" + username);
//根据用户名查询数据库获得用户信息(包含数据库中存储的密码信息)
User user = map.get(username);//模拟查询根据用户名查询数据库
if(user == null){
//用户名不存在
return null;
}else{
//将用户信息返回给框架
//框架会进行密码比对(页面提交的密码和数据库中查询的密码进行比对)
List<GrantedAuthority> list = new ArrayList<>();
//为当前登录用户授权,后期需要改为从数据库查询当前用户对应的权限
list.add(new SimpleGrantedAuthority("permission_A"));//授权
list.add(new SimpleGrantedAuthority("permission_B"));
if(username.equals("admin")){
list.add(new SimpleGrantedAuthority("ROLE_ADMIN"));//授予角色
}
org.springframework.security.core.userdetails.User securityUser = new org.springframework.security.core.userdetails.User(username,"{noop}"+user.getPassword(),list);
return securityUser;
}
}
}
在Spring-security.xml中配置组建扫描，扫描controller
<mvc:annotation-driven></mvc:annotation-driven>
<context:component-scan base-package="com.itheima.controller"></context:component-scan>
开启注解方式权限控制
<!--开启注解方式权限控制-->
<security:global-method-security pre-post-annotations="enabled" />
创建controller类并使用权限注解
package com.itheima.controller;
?
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
?
@RestController
@RequestMapping("/hello")
public class HelloController {
@RequestMapping("/add")
@PreAuthorize("hasAuthority(‘add‘)")//表示用户必须拥有add权限才能调用当前方法
public String add(){
System.out.println("add...");
return "success";
}
?
@RequestMapping("/delete")
@PreAuthorize("hasRole(‘ROLE_ADMIN‘)")//表示用户必须拥有ROLE_ADMIN角色才能调用当前方法
public String delete(){
System.out.println("delete...");
return "success";
}
}
<security:logout logout-url="/logout.do"
logout-success-url="/login.html" invalidate-session="true"/>
