spring 统一异常拦截 ,定制自己的返回code以及返回的message

新建如下JAVA文件即可



@Slf4j
@RestControllerAdvice
public class GlobalExceptionAdvice {

    private String profile;
   
    @ExceptionHandler(MethodArgumentNotValidException.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public ResponseObj bindException(MethodArgumentNotValidException e) {
        BindingResult bindingResult = e.getBindingResult();

        StringBuffer errorMesssage = new StringBuffer();

        for (FieldError fieldError : bindingResult.getFieldErrors()) {
            errorMesssage .append(fieldError.getDefaultMessage() + ", ");
        }
        //  此处代码为项目内统一返回java类 这里不做该类展示
        ResponseObj response = ResponseObj.setResultCode(ResultCode.FAIL_ILLEGAL_ARGUMENT);
        response.getStatus().setMessage(errorMesssage.toString());

        return response;
    }
    @ExceptionHandler(Exception.class)
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public ResponseObj exception(Exception ex) {
        log.error("", ex);
        StringWriter stringWriter = new StringWriter();
        ex.printStackTrace(new PrintWriter(stringWriter));
        ResponseObj response =ResponseObj.setResultCode(ResultCode.FAIL_UNKNOWN,stringWriter.toString());
       return response;
    }

}
