spring mvc上传文件超过设定大小异常处理客户端无响应;
controller类
@RequestMapping(path = "/file", method = RequestMethod.POST)
public UploadMsg uploadFile(@RequestParam("uploadFile") MultipartFile file, String userCode) throws Exception {
String fileId = genFileId();
saveFileToSystem(file, fileId);
UploadMsg uploadMsg = getUploadMsg(userCode, fileId, file.getSize());
return uploadMsg;
}
@ExceptionHandler(MaxUploadSizeExceededException.class)
public ResponseEntity<String> handleException(MaxUploadSizeExceededException ex) {
System.out.println("=====================" + ex.getClass().getName());
return ResponseEntity.ok("ok");
}spring配置文件配置文件大小不能超过1M
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"/>
<property name="maxUploadSize" value="#{1*1024*1024}"/>
<property name="resolveLazily" value="true"/>
</bean>下面是我用小于1M的文件访问时的情况
这是上传失败的情况
下面是我的日志打印情况

这句是我在@ExceptionHandler(MaxUploadSizeExceededException.class)注解的方法中打印的，我也在这个方法中作了响应处理，但是客户端访问的时候就会显示无响应，不知道是什么鬼，求大神解答！！！！

Spring mvc MaxUploadSizeExceededException の無限ループ解決策についての答えをここで見つけました。
Tomcat のバグであると言われています。jetty で実行してみましたが、下位バージョンに関しては問題ありませんでした。 Tomcat、まだテストしていません。

Weblogic にもこの問題があり、画像のアップロードがタイムアウトになり、クライアントのステータスがまだ保留中であり、マップ オブジェクトを返すように @ExceptionHandler と @ResponseBody が記述されていますが、クライアントは応答しません。 WebLogic が応答を処理していないと思われます
