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" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%><%@ taglib prefix="s" uri="/struts-tags" %>
     
     
     
         
          
          
          
      
     

 

UploadsAction.java

package com.lcw.struts2.upload;import java.io.File;import java.io.IOException;import org.apache.commons.io.FileUtils;import org.apache.struts2.ServletActionContext;import com.opensymphony.xwork2.ActionSupport;public class UploadsAction extends ActionSupport {    // 
         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    public void setUpload(File[] upload) {        this.upload = upload;    }    public void setUploadContentType(String[] uploadContentType) {        this.uploadContentType = uploadContentType;    }    public void 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;    }}

struts.xml

     
         
          
              
          
          
              
                   
        
         /index.jsp
                    
        
         /upload.jsp
