2 DAO

• IRoleDAO

public interface IRoleDao {

    @Select("select * from role where id in (select roleId from users_role where userId = #{userId})")
    public List<Role> findRoleByUserId(String userId) throws Exception;
}

• IUserDao

public interface IUserDao {

    @Select("select * from users where username=#{username}")
    @Results({
            @Result(id=true,property = "id",column = "id"),
            @Result(property = "username", column ="username"),
            @Result(property = "email", column ="email"),
            @Result(property = "password", column ="password"),
            @Result(property = "phoneNum", column ="phoneNum"),
            @Result(property = "status", column ="status"),
            @Result(property = "roles",column = "id",javaType = java.util.List.class,
            many =@Many(select = "com.tzb.dao.IRoleDao.findRoleByUserId"))

    })
    public UserInfo findByUserName(String username) throws Exception;
}

3 Service

• 接口

package com.tzb.service;

import org.springframework.security.core.userdetails.UserDetailsService;

public interface IUserService extends UserDetailsService {
}

• 實現類

@Service("userService")
@Transactional
public class UserServiceImpl implements IUserService {

    @Autowired
    private IUserDao userDao;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        UserInfo userInfo = null;
        try {
            userInfo = userDao.findByUserName(username);
        } catch (Exception e) {
            e.printStackTrace();
        }

        // 自己的用戶對象封裝成 UserDetails的實現類User
//        User user = new User(userInfo.getUsername(), "{noop}" + userInfo.getPassword(),
//                getAuthority(userInfo.getRoles()));

        User user = new User(userInfo.getUsername(), "{noop}" + userInfo.getPassword(),
                userInfo.getStatus() == 0 ? false : true,
                true,
                true,
                true,
                getAuthority(userInfo.getRoles()));
        return user;
    }

    // 集合中裝入的是角色的描述
    private List<SimpleGrantedAuthority> getAuthority(List<Role> roles) {
        List<SimpleGrantedAuthority> list = new ArrayList<>();
        for (Role role : roles) {
            list.add(new SimpleGrantedAuthority("ROLE_" + role.getRoleName()));
        }
        return list;
    }
}
