背景是获取Controller类输出的结果数据。

实现方案，使用@RestControllerAdvice+ResponseBodyAdvice接口。不能使用Interceptor，在执行Interceptor时，response已经提交。也可以考虑aspect方案，不过实现麻烦些，增加较多的代码，效率低。

@Slf4j
@RestControllerAdvice
public class GlobalExceptionAndAdviceHandler implements ResponseBodyAdvice<Payload> {@ResponseStatus(HttpStatus.OK)@ExceptionHandler(RuntimeException.class)public Payload handleRuntimeException(RuntimeException ex) {log.error(ex.getMessage(), ex);return Payload.fail(HttpStatus.INTERNAL_SERVER_ERROR.value(), ex.getMessage(), null);}@Overridepublic boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {/*判断方法参数是否为Payload*/return returnType.getParameterType().isAssignableFrom(Payload.class);}@Overridepublic Payload beforeBodyWrite(Payload body, MethodParameter returnType, MediaType selectedContentType,Class<? extends HttpMessageConverter<?>> selectedConverterType,ServerHttpRequest request, ServerHttpResponse response) {/*日志输出body*/log.info("request.url={},response.data: {}",request.getURI().getPath(), JSON.toJSONString(body));return body;}

• Payload 类为Controller统一返回的参数
• 如果发生异常先执行handleRuntimeException再执行beforeBodyWrite

输出效果：
