struts2.1整合spring2.5后使用fileUpload的文件上传

struts2.1单独使用fileUpload没有问题,可以正常使用。

但是整合了spring2.5.6之后,就出现了一个让我匪夷所思的问题。

问题是这样:整合后,再上传文件,如果符合fileUpload的要求,那么上传没问题。

但是,如果文件上传的类型或者文件的大小不符合要求,那么本次上传失败。这也没问题。

问题是,在失败之后,我刷新页面,上传一个符合要求的文件,还是显示上传失败的信息。

而且文件的确上传失败了,后台也不走action了,感觉被fileUpload直接拦截了,

并且拦截器,获得的还是以前那个失败的信息。这个我就晕了。

有谁知道这个问题产生的原因是什么吗?请告知!谢谢!

以下是我使用的代码:

按照你说的我将


改为

结果。。。。。。,抛了个异常

晕死,难道是不能这样用,还是我哪里用错了呢,唉,

原来以为我已经会整合ssh2了,结果今天才发现自己的无知!!!
[b]问题补充:[/b]

太阳啊,搞了一天了,终于知道问题出在哪里了

我太阳。。。。。。。。。。。。。。。。。。。。

单词写错了,太TM丢人了。。。。。。。。

prototype --- 我写的是 propotype :twisted:

另外我的springbean没有 singleton

只有scope,估计是版本的问题吧。

我用的是spring2.5.6

3个回答

spring配置里 bean默认是单例的 把 bean 的singleton设置为false 实验下

用这个试验下
