struts2+swfupload多文件上传

上传页面代码
swfupload参数网上都有，可以查一下

upload_url: "uploadAction.action"//上传文件所请求的action

file_post_name:接收文件的aciton属性
在action中还要加上*FileName,*就是file_post_name你所设置的，然后设置setget方法。

button开头的是设置按钮属性

uploadsuccess等是设置回调，都在handler.js中.

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

}
}

struts.xml
<action name="uploadAction" class="com.xpec.action.FileUpLoadAction" method="fileUpLoad">
<result name="success">/index.jsp</result>
</action>
上传成功之后会找寻index.jsp也就是你配置的，不回调转但是会找，会跳到handler.js里的uploadsuccess，serverdata就是index.jsp内容你需要用正则表达式取出相应的数据来

判断是否上传成功，弹出相应提示。

fileupload.jsp,fileuploadaction.action, index.jsp这个三文件是上传代码。其他的只是随意的测试。[size=large] [/size]
