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

=====================org.springframework.web.multipart.MaxUploadSizeExceededException
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！！！！
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。
@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。
