分段文件上传：大小超出Spring Boot异常返回JSON错误消息

据我所知，您可以使用此文件处理多部分文件异常。

@ControllerAdvicepublic class MyErrorController extends ResponseEntityExceptionHandler {Logger logger = org.slf4j.LoggerFactory.getLogger(getClass());@ExceptionHandler(MultipartException.class)@ResponseBodyString handleFileException(HttpServletRequest request, Throwable ex) {    //return your json insted this string.    return "File upload error";  }}
