Spring AOP 后置通知修改响应httpstatus

1.定义Aspect

/**
 * 响应体切面
 * 后置通知修改httpstatus
 *
 * @author ： CatalpaFlat
 */
@Component
@Aspect
public class ApiResponseAspect {
    private Logger logger = LoggerFactory.getLogger(this.getClass());
    /**
     * 切面
     */
    private final String POINT_CUT = "execution(* com.xxx.web.controller..*(..))";

    @Pointcut(POINT_CUT)
    private void pointcut() {
    }

    @AfterReturning(value = POINT_CUT, returning = "apiResponse", argNames = "apiResponse")
    public void doAfterReturningAdvice2(ApiResponse apiResponse) {
        logger.info("apiResponse：" + apiResponse);
        Integer state = apiResponse.getState();
        if (state != null) {
            ServletRequestAttributes res = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            res.getResponse().setStatus(state);
        }
    }
}

2.使用

2.1.请求体

return ApiUtil.error(HttpStatus.UNSUPPORTED_MEDIA_TYPE.value(),"the request body is empty");

2.2.参数缺失

return ApiUtil.error(HttpStatus.BAD_REQUEST.value(),"Parameter id is empty");

2.3.权限认证

return ApiUtil.error(HttpStatus.UNAUTHORIZED.value(),"Current requests need user validation");

2.4.与资源存在冲突

return ApiUtil.error(HttpStatus.CONFLICT.value(),"Conflict with resources");

2.5.携带error信息

return ApiUtil.error(HttpStatus.BAD_REQUEST.value(),"There are some mistakes",obj);

3.ApiResponse响应体

public class ApiResponse {
    private Integer state;
    private String message;
    private Object result;
    private Object error;
}

4.ApiUtil

public class ApiUtil {
    /**
     * http回调错误
     */
    public static ApiResponse error(Integer code, String msg) {
        ApiResponse result = new ApiResponse();
        result.setState(code);
        result.setMessage(msg);
        return result;
    }

    /**
     * http回调错误
     */
    public static ApiResponse error(Integer code, String msg,Object error) {
        ApiResponse result = new ApiResponse();
        result.setState(code);
        result.setMessage(msg);
        result.setError(error);
        return result;
    }
}
