多部分文件上载:弹出引导返回JSON错误消息中的大小超过异常

我知道你可以通过使用它来处理多部分文件异常.

@ControllerAdvice
public class MyErrorController extends ResponseEntityExceptionHandler {

Logger logger = org.slf4j.LoggerFactory.getLogger(getClass());

@ExceptionHandler(MultipartException.class)
@ResponseBody
String handleFileException(HttpServletRequest request, Throwable ex) {
    //return your json insted this string.
    return "File upload error";
  }
}
