swfupload v2.2 或者2.5在struts1+spring+hibernate项目中 一开始的时候能上传文件，后来就不行了，让我很纳闷，网上也找了很多资料 ，但是没有提到我遇到的这个问题，

strtuts1 xml:
<action path="/acl/FileManagerAction" type="com.sunland.action.acl.FileManagerAction"
name="sysFilesForm" scope="request" parameter="method">
<forward name="index" path="/WEB-INF/webpages/file/filemanager.jsp"
redirect="false" />
</action>
web.xml里涉及strtus1的：
<!-- Struts的配置 -->
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>

<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
网上看到struts2遇到这个问题的解决办法是过滤器里把/*改成 *.action
这个我这个虽然是strtus1但是我应该也没有哪里做了全路径拦截
解决办法：
把访问strustaction类改成访问servelt
不访问 strtus的action、
我的servelet是这样写的，当然里面有一些涉及数据库的操作 遇到同样问题的人只要参考文件操作的代码就好了

servlet的web.xml配置 很简单
<!-- 文件批量上传 start -->
<servlet>
<description>file upload</description>
<display-name>file upload</display-name>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>com.sunland.servelet.UploadFile</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/servlet/UploadServlet</url-pattern>
</servlet-mapping>
<!-- 文件批量上传 end -->
这样swfupload的就可以上传了 另外我改了几个 官网的php例子，可以上传批量文件，文件名称是swfobjectdemo，里面的改了可以上传，其他的没改道理一样把upload.php拷贝过去就好了，官网下载下来的是没有保存文件的，有兴趣的朋友可以下载学习。版本是最新的swfupload v2.5
另外这里放了一个 纯servlet上的例子 这是网上找的，你们可以参考
