webwork2中多文件上传的处理作者:onebody(onebodysoftware@hotmail.com)
1. webwork-default.xml 配置 (拦截器的配置)

<interceptor-stack name="fileUploadStack">

<interceptor-ref name="fileUpload"/>

<interceptor-ref name="basicStack"/>

</interceptor-stack>

</interceptors>

2. xwork.xml 配置 (处理的Action配置)

<result name="main">fileUploadIndex.jsp</result>

<interceptor-ref name="fileUpload"/>

</action>

</package>

3. webwork.properties 配置

/*多文件上传单个文件上传时直接用pell就行了
单文件与多文件上传的处理有所不同详细Action类中的描述*/

webwork.multipart.parser=jakarta

3. fileUploadIndex.jsp 代码

<html>

<head><title>多文件上传实例</title></head>

function addAccessory() {

var accessoryListObj = document.getElementById("accessoryList");

var accObj = document.createElement("span");

var spanId = (new Date()).getTime();

var spanHTML = " <input name=files type=file width=100px/><input type=button value=删除 onclick=deleteFile('" + spanId + "')><br>";

accObj.setAttribute("id", spanId);

accObj.setAttribute("width", "100px");

accObj.innerHTML = spanHTML;

accessoryListObj.appendChild(accObj);

}

function deleteFile(fileId) {

var accessoryListObj = document.getElementById("accessoryList");

var accObj = document.getElementById(fileId);

accessoryListObj.removeChild(accObj);

}

</script>

<body>

<tbody>

<tr>

<span title="增加附件"

onclick="addAccessory()"

style="cursor:pointer;color:blue;"><strong>[添加附件]</strong></span>

</td>

</tr>

<tr>

<div id="accessoryList"

style="overflow-x:hidden;overflow-y:auto;width:100%;height:100%;">

</div>

</td>

</tr>

<tr>

</td>

</tr>

</tbody>

</table>

</form>

</body>

</html>

4.com.omyos.fileUpload.UploadAction.java 代码

public class DataInfoAction extends ActionSupport{

private File[] files; //多个文件对象数组

private String[] filesFileName; //文件对应的真实文件名单个文件上传时不需要此属性定义

//多文件上传时 file.getName() 无效,取得不是真实的文件名,而是upload_xxx.tmp

public String execute() {

if (files != null) {

for (int i = 0; i < files.length; i++) {

File file = files[i];

String fileName = filesFileName[i];

System.out.print(" name:=" + file.getName() + " ");

System.out.print(" fileName:=" + fileName + " ");

System.out.print(" path:=" + file.getPath() + " ");

System.out.print(" ");

//文件上传的代码自己code吧...
