springboot返回数据封装

返回数据封装

1.实现ResponseBodyAdvice，加入注解RestControllerAdvice，在beforeBodyWrite中实现

@RestControllerAdvice
public class ResponseResultBodyAdvice
  implements ResponseBodyAdvice<Object>
{
  private static final Logger log = LoggerFactory.getLogger(ResponseResultBodyAdvice.class);
  private static final Class<? extends Annotation> ANNOTATION_TYPE = ResultJson.class;
  @Autowired
  private ObjectMapper objectMapper;
  
  public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType)
  {
    return true;
  }
  
  public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response)
  {
    if ((body instanceof BaseResponse))
    {
      BaseResponse baseResponse = (BaseResponse)body;
      StringBuilder sb = new StringBuilder();
      sb.append("请求的服务端方法:").append(((ServletServerHttpRequest)request).getServletRequest().getRequestURI());
      return Result.failure(baseResponse.getCode(), baseResponse.getMessage(), sb.toString());
    }
    if ((body instanceof Result)) {
      return body;
    }
    return Result.success(body);
  }
}
