spring mvc上传文件超过设定大小异常处理客户端无响应

Question

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22:40:28,569 DEBUG http-apr-8080-exec-5 support.DefaultListableBeanFactory:251 - Returning cached instance of singleton bean 'uploadFileController'=====================org.springframework.web.multipart.MaxUploadSizeExceededException22:40:28,574  WARN http-apr-8080-exec-5 commons.CommonsMultipartResolver:194 - Failed to perform multipart cleanup for servlet requestorg.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size of 1048576 bytes exceeded; nested exception is org.apache.commons.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (6145455) exceeds the configured maximum (1048576) 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！！！！

Answer 1

从这里找到了答案关于spring mvc MaxUploadSizeExceededException 死循环解决方
据说是tomcat的bug,我试了下用jetty运行，果然是没有问题的，至于低版本的tomcat还没测试。

Answer 2

@ExceptionHandler(MaxUploadSizeExceededException.class)

@ResponseBody

public ResponseEntity<String> handleException(MaxUploadSizeExceededException ex) {

    System.out.println("=====================" + ex.getClass().getName());

    return ResponseEntity.ok("ok");

}

看看是不是少了个@ResponseBody。

Answer 3

weblogic也有这个问题，图片上传超时了，客户端status还是pending，没有响应，已经写了@ExceptionHandler和@ResponseBody,返回一个map对象，但是客户端没有响应，怀疑weblogic没做响应处理
