下载 swfupload 文件夹 里面包含handlers.js，swfupload.js，swfupload.swf 三个文件。
我的是和ssh项目整合在一起的。因为struts2的拦截器会拦截所有请求，在跳转到上传文件的servlet中时request请求会被转换为struts的请求。所以要去掉struts的请求。
假如web.xml配置的拦截所有请求，可以修改这里，不拦截所有
<filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter </filter-class> <init-param> <param-name>config</param-name> <param-value> struts-default.xml,struts-plugin.xml,resources/struts/struts.xml </param-value> </init-param> <init-param> <param-name>actionPackages</param-name> <param-value>com.yuncai.modules</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
或者在struts.xml中加上 <constant name="struts.action.excludePattern" value="/servlet/.*" /> struts不会拦截这个路径下的所有
上传文件的servlet的路径
