java - 如何处理响应代码？

Question

我需要发送取决于响应代码的不同 json。

 @ApiOperation(value = "saveObject", nickname = "saveObject", httpMethod = "POST")
        @ApiResponses(value = {
                @ApiResponse(code = 200, message = "Success"),
                @ApiResponse(code = 404, message = "Not Found"),
                @ApiResponse(code = 500, message = "Failure")})
        @PostMapping(value = "/save")
        public void saveUser(@RequestBody ObjectView object) {
            objectService.saveObject(object);
        }

示例:如果代码是 200，则应发送

data: {
        “result”:”success”
    }

如果500

 data: {
        “error”:”500”
    }

如何使用 ResponseBodyAdvice 做到这一点？

@RestControllerAdvice
public class ResponseView implements ResponseBodyAdvice<Object> {
    @Override
    public boolean supports(MethodParameter methodParameter, Class<? extends HttpMessageConverter<?>> aClass) {
        return true;
    }

    @Override
    public Object beforeBodyWrite(Object o, MethodParameter methodParameter, MediaType mediaType,
                                  Class<? extends HttpMessageConverter<?>> aClass, ServerHttpRequest serverHttpRequest,
                                  ServerHttpResponse serverHttpResponse) {
        return new WrapperObj<Object>(o);
    }

    @JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY)
    @JsonSerialize
    private class WrapperObj<T> {
        private final Object data;

        public WrapperObj(Object data) {
            this.data = data;
        }
    }
}

我是这样做的:

import org.springframework.http.HttpStatus;
public Object beforeBodyWrite(Object o, MethodParameter methodParameter, MediaType mediaType, Class<? extends HttpMessageConverter<?>> aClass, ServerHttpRequest serverHttpRequest, ServerHttpResponse serverHttpResponse) {

HttpServletResponse servletResponse = ((ServletServerHttpResponse) serverHttpResponse).getServletResponse();

if(servletResponse.getStatus() == 200) {
        return createYourResponseBodyE_G_200().getBody();

 } else if(servletResponse.getStatus() == 500) {
        return createYourResponseBodyE_G_500().getBody();
 }


public ResponseEntity<Object> createYourResponseBodyE_G_200() {

        return new ResponseEntity<Object>(  "data: { \"result\":\"success\" }", HttpStatus.OK);

}

public ResponseEntity<Object> createYourResponseBodyE_G_500() {

        return new ResponseEntity<Object>(  "data: { \"error\":\"500\" }", HttpStatus.INTERNAL_SERVER_ERROR);

}
