struts2.0多文件上传（我自己用，好用，中文也可以上传）
这个页面是点一个添加就出一个浏览上传的
<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<script language="javascript">
function addComponent()
{
var uploadHTML = document.createElement( "<input type='file' name='upload'/>");
document.getElementById("files").appendChild(uploadHTML);
uploadHTML = document.createElement( "<p/>");
document.getElementById("files").appendChild(uploadHTML);
}
</script>
</head>
<body>
<s:fielderror/>
<input type="button" onclick="addComponent();" value="添加文件" /><br />
<form onsubmit="return true;" action="upload.action" method="post" enctype="multipart/form-data"><span id="files">
<input type='file' name='upload' /><p /></span>
<input type="submit" value="上传" />
</form>
</body>
</html>
写个action类
package org.qiujy.web.struts2;
import java.io.*;
import com.opensymphony.xwork2.ActionSupport;
public class UploadMoreAction extends ActionSupport {
private java.util.List uploads;
private java.util.List fileNames;
private java.util.List uploadContentTypes;
public java.util.List getUploadFileName() {
return fileNames;
}
public void setUploadFileName(java.util.List fileNames) {
this.fileNames = fileNames;
}
public java.util.List getUpload() {
return uploads;
}
public void setUpload(java.util.List uploads) {
this.uploads = uploads;
}
public void setUploadContentType(java.util.List contentTypes) {
this.uploadContentTypes = contentTypes;
}
public java.util.List getUploadContentType() {
return this.uploadContentTypes;
}
public String execute() throws Exception {
if (uploads != null) {
int i = 0;
for (; i < uploads.size(); i++) {
java.io.InputStream is = new java.io.FileInputStream((String) uploads.get(i));
java.io.OutputStream os = new java.io.FileOutputStream(
"e:\\mydir\\" + fileNames.get(i));
byte buffer[] = new byte[8192];
int count = 0;
while ((count = is.read(buffer)) > 0) {
os.write(buffer, 0, count);
}
os.close();
is.close();
}
}
return SUCCESS;
}
}
