重写UserDetailsService(效验)

@Service
public class UserDetailsServiceImpl implements UserDetailsService {
    @Autowired
    private UserMapper userMapper;
    @Override
    public UserDetails loadUserByUsername(String username) throws
            UsernameNotFoundException {
        //根据用户名查询用户信息
        LambdaQueryWrapper<User> wrapper = new LambdaQueryWrapper<>();
        wrapper.eq(User::getUserName,username);
        User user = userMapper.selectOne(wrapper);
        //如果查询不到数据就通过抛出异常来给出提示
        if(Objects.isNull(user)){
            throw new RuntimeException("用户名或密码错误");
        }
//        //TODO 根据用户查询权限信息 添加到LoginUser中
//
//        User user=new User();
//        user.setUserName(username);
//        //封装成UserDetails对象返回
        return new LoginUser(user);
    }
}

public class LoginUser implements UserDetails {
    private User user;
    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return null;
    }

    @Override
    public String getPassword() {
        return user.getPassword();
    }

    }

    @Override

        return true;
    }
}
