这个是错误信息

Answer 1

ModelAndView: materialized View is [null];
也就是说你上传的图片没有保存进这个对象中
你检查一下

Answer 2

我的资源里有个java上传源代码,包含检查文件大小、格式等功能，运行OK，有需要的朋友可以去看看
嗯，还有个struts1.2写的文件上传源码，也不错的

Answer 3

protected ModelAndView onSubmit(HttpServletRequest request, 
HttpServletResponse response, Object command, BindException errors) 
throws Exception {
--------------------
这样的技术还在用么?是不是有点过时了!

Answer 4

用得着写那么长的代码吗，struts不是提供了一个上传文件的功能
