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

bash 复制代码

@Service
public class MyUserDetailServiceImpl implements UserDetailsService {

    @Autowired
    SysUserService sysUserService;

    @Override
    public 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：

bash 复制代码

@Service
public class SysUserServiceImpl extends ServiceImpl<SysUserMapper, SysUser>
    implements SysUserService{


    @Override
    public SysUser getByUsername(String username) {
        return getOne(new QueryWrapper<SysUser>().eq("username",username));
    }
}

SecurityConfig配置类里面配置下MyUserDetailServiceImpl

配置下默认加密bean

bash 复制代码

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

自定义异常UserCountLockException

bash 复制代码

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：

bash 复制代码

@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());
    }
    
}
