java批量上传
下載?swfupload 文件夾 里面包含handlers.js，swfupload.js，swfupload.swf 三個文件。
我的是和ssh項目整合在一起的。因為struts2的攔截器會攔截所有請求，在跳轉到上傳文件的servlet中時request請求會被轉換為struts的請求。所以要去掉struts的請求。
假如web.xml配置的攔截所有請求，可以修改這里，不攔截所有
<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不會攔截這個路徑下的所有
