第10讲用户登录SpringSecurity查库实现

用户登录SpringSecurity查库实现

security包下新建MyUserDetailServiceImpl

@Service
public class MyUserDetailServiceImpl implements UserDetailsService {@AutowiredSysUserService sysUserService;@Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {SysUser sysUser = sysUserService.getByUsername(username);if(sysUser==null){throw new UsernameNotFoundException("用户名或者密码错误！");}else if("1".equals(sysUser.getStatus())){throw new UserCountLockException("该用户账号已被封禁，具体联系管理员！");}return new User(sysUser.getUsername(),sysUser.getPassword(),getUserAuthority(sysUser.getId()));}private List<GrantedAuthority> getUserAuthority(Long id) {return new ArrayList<>();}
}

getByUsername实现：

@Service
public class SysUserServiceImpl extends ServiceImpl<SysUserMapper, SysUser>implements SysUserService{@Overridepublic SysUser getByUsername(String username) {return getOne(new QueryWrapper<SysUser>().eq("username",username));}
}

SecurityConfig配置类里面配置下MyUserDetailServiceImpl

在这里插入图片描述

配置下默认加密bean

@Bean
BCryptPasswordEncoder bCryptPasswordEncoder(){return new BCryptPasswordEncoder();
}

自定义异常UserCountLockException

public class UserCountLockException extends AuthenticationException {public UserCountLockException(String msg, Throwable t) {super(msg, t);}public UserCountLockException(String msg) {super(msg);}
}

全局异常GlobalExceptionHandler：

@Slf4j
@RestControllerAdvice
public class GlobalExceptionHandler {@ExceptionHandler(value = RuntimeException.class)public R handler(RuntimeException e){log.error("运行时异常：----------------{}", e.getMessage());System.out.println("运行时异常：");return R.error(e.getMessage());}}
