Struts2简单多文件上传，解决文件名乱码

1、建立javaWeb工程fileUpload

2、在Web-Root下新建upload.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>   
    <title>my file upload</title>
  </head>
  <body>					<!-- enctype为form属性，表明以二进制方式处理数据 -->
    <s:form action="uploadAction" method="post" enctype="multipart/form-data">
		<s:file name="upload" label="文件上传1"></s:file>
		<s:file name="upload" label="文件上传2"></s:file>
		<s:file name="upload" label="文件上传3"></s:file>
    	<s:submit value="上传"></s:submit>
    </s:form>
  </body>
</html>

3、在src>com.action包下新建UploadAction.java

package com.action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.List;
import java.util.logging.Logger;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class UploadAction extends ActionSupport{	
	private List<File> upload;	//上传的文件
	private List<String> uploadFileName;//上传的文件名
	public List<File> getUpload() {
		return upload;
	}
	public void setUpload(List<File> upload) {
		this.upload = upload;
	}
	public List<String> getUploadFileName() {
		return uploadFileName;
	}
	public void setUploadFileName(List<String> uploadFileName) {
		this.uploadFileName = uploadFileName;
	}
	public String execute() throws Exception{
		
		if(upload!=null){
			for(int i=0;i<upload.size();i++){
				InputStream is=new FileInputStream(upload.get(i));//获取文件的输入流
				OutputStream os=new FileOutputStream("d:\\upload\\"+getUploadFileName().get(i));//指定输出流地址
				byte buffer[] = new byte[1024];
				int count=0;
				while((count=is.read(buffer))>0){
					os.write(buffer,0,count);
				}
				os.close();
				is.close();
			}
		}	
		return SUCCESS;
	}
}

4、在src下新建struts.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>	
	<!-- <constant name="struts.custom.i18n.resources" value="message"></constant> -->	
	<package name="default" extends="struts-default">
		
		<action name="uploadAction" class="com.action.UploadAction">
			<result>/success.jsp</result>
		</action>
		
	</package>
	<constant name="struts.multipart.saveDir" value="/tmp"></constant>
</struts>

5、success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head> 
    <title>file upload</title>
  </head>
  
  <body>
    File Upload Success!
  </body>
</html>

6、测试结果

注意！！如果遇到的上传的文件名是乱码，可能原因是文件名变量不是uploadFileName。
