之前写过一篇文章，关于Struts2文件上传：http://www.cnblogs.com/lichenwei/p/3927964.html

现在来说下多文件上传，其实就把上传文件当成是一个数组去处理，和单文件上传是一样的思路，直接贴一段代码：

uploads.Jsp

<%@ page language="java ContentTypetext/HTML; charset=utf-8 pageEnCodingutf-8"%>
@ taglib prefixs uri/struts-Tags" %>
<!DOCTYPE HTML PUBliC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/HTML4/loose.dtd">
<HTMLheadMeta http-equiv="Content-Type" content="text/HTML; charset=ISO-8859-1"Title>上传文件示例</bodys:actionerror/>
s:fIElderrors:form action="uploads.action" theme="simple" namespace="/" method="post" enctype="multipart/form-data">
    s:file label="上传文件：" name="upload"></s:files:submit value="提交上传"s:submits:form>

UploadsAction.java

package com.lcw.struts2.upload;

import java.io.file;
 java.io.IOException;

 org.apache.commons.io.fileUtils;
 org.apache.struts2.ServletActionContext;

 com.opensymphony.xwork2.ActionSupport;

public class UploadsAction extends ActionSupport {
    // <s:file label="上传文件：" name="upload"></s:file>
    private file[] upload; 命名应该和上传页面name属性值保持一致
    private String[] uploadContentType; 属性值+ContentType
    private String[] uploadfilename; 属性值+FIElname

    voID setUpload(file[] upload) {
        this.upload = upload;
    }

     setUploadContentType(String[] uploadContentType) {
        this.uploadContentType = uploadContentType;
    }

     setUploadfilename(String[] uploadfilename) {
        this.uploadfilename = uploadfilename;
    }

    public String upload() {

        for (int i = 0; i < upload.length; i++) {
            file destfile = new file(ServletActionContext.getServletContext()
                    .getRealPath("/uploads")
                    + "/" + uploadfilename[i]);
            try {
                 工具类
                fileUtils.copyfile(upload[i],destfile);
            } catch (IOException e) {
                e.printstacktrace();
            }

        }
        return SUCCESS;
    }
}
