• 编写实体类

  package com.xsw.pojo;
  
  import lombok.AllArgsConstructor;
  import lombok.Data;
  import lombok.NoArgsConstructor;
  
  @Data
  @AllArgsConstructor
  @NoArgsConstructor
  public class User {
      String ano;
      String apwd;
      String aname;
      String uninfo;
  }
  
  

• mapper

  package com.xsw.mapper;
  
  import com.xsw.pojo.User;
  import org.apache.ibatis.annotations.Mapper;
  import org.springframework.stereotype.Repository;
  
  @Repository
  @Mapper
  public interface UserMapper {
      public User queryUserByName(String name);
  }
  

• mapper.xml

  <?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE mapper
          PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
          "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  <mapper namespace="com.xsw.mapper.UserMapper">
  
  
      <select id="queryUserByName" parameterType="String" resultType="user">
         select * from admin where aname = #{aname};
      </select>
  
  
  </mapper>
  

• 测试数据库是否连接成功

  @Autowired
      UserService userService;
  
      @Test
      void contextLoads() {
          System.out.println(userService.queryUserByName("小辛"));
      }
  
  

• 连接真实数据库 UserRealm

          UsernamePasswordToken usertoken =(UsernamePasswordToken) token;
  
          //连接真实数据库
          User user = userService.queryUserByName(usertoken.getUsername());
  
          if (user==null) {
              return null;
  
          }
  

10.2.5 请求授权实现

• shiroConfig

           //必须带有  user:add  才能访问
         filterChainDefinitionMap.put("/user/add","perms[user:add]");
          //必须带有  user:update  才能访问
          filterChainDefinitionMap.put("/user/update","perms[user:update]");
          //登陆验证
          filterChainDefinitionMap.put("/user/*","authc");
  
  
  
          bean.setFilterChainDefinitionMap(filterChainDefinitionMap);
  
          //设置登录的请求
         bean.setLoginUrl("/toLogin");
         //设置未授权的请求
         bean.setUnauthorizedUrl("/uninfo");
          return bean;
  

• controller

  @RequestMapping("/uninfo")
        @ResponseBody
        public String uninfo(){
          return "未经授权不能访问";
        }
  

• UserRealm

  SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
          //info.addStringPermission("user:add");
  
  //拿到当前的对象
          Subject subject = SecurityUtils.getSubject();
          User principal = (User) subject.getPrincipal();
          info.addStringPermission(principal.getUninfo());
          return info;
  
  
  
  
   //密码认证 shiro 做~        user
          return new SimpleAuthenticationInfo(user,user.getApwd(),"");
