VO中，部分参数校验失败

程序中添加这类校验性异常，统一异常处理： @RestControllerAdvice @Slf4j public class ExceptionAdvice { @ExceptionHandler(Exception.class) public Response<?> handleException(Exception e) { return Response.error( e.getMessage()); } /** * 拦截参数校验异常 */ @ExceptionHandler(MethodArgumentNotValidException.class) public Response<?> handleMethodArgumentNotValidException(MethodArgumentNotValidException methodArgumentNotValidException) { StringBuilder errorMessage=new StringBuilder(); List objectErrors=methodArgumentNotValidException.getBindingResult().getAllErrors(); if (!CollectionUtils.isEmpty(objectErrors)) { for (int i = 0; i < objectErrors.size(); i++) { if (i == 0) { errorMessage.append(objectErrors.get(i).getDefaultMessage()); } else { errorMessage.append(","); errorMessage.append(objectErrors.get(i).getDefaultMessage()); } } }else { errorMessage.append("MethodArgumentNotValidException occured."); } return Response.error("400", errorMessage.toString(),null); } }
