spring mvc上传文件超过设定大小异常处理客户端无响应：请求的连接被重置

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
