Spring Boot怎么处理上传文件时出现的MultipartException

Answer 1

参考：
@ExceptionHandler({ MultipartException.class, FileSizeLimitExceededException.class,
SizeLimitExceededException.class })
public ResponseEntity<Attachment> handleUploadrException(HttpServletRequest request, Throwable ex) {
Attachment result = new Attachment();
result.setDescription(ex.getMessage());
HttpStatus status = getStatus(request);
return new ResponseEntity<Attachment>(result, status);
}

private HttpStatus getStatus(HttpServletRequest request) {
Integer statusCode = (Integer) request.getAttribute("javax.servlet.error.status_code");
if (statusCode == null) {
return HttpStatus.INTERNAL_SERVER_ERROR;
}
return HttpStatus.valueOf(statusCode);
}
