1首先是配置web文件其实也没有什么好配置的简单
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>upload</display-name>//对项目的描述
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>
2 配置struts.xml
<?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>
<package name="login" extends="struts-default">
<action name="xiaobai" class="com.xiaobai.action.LoginAction">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>

</action>

</package>

</struts>
3写对应的类
package com.xiaobai.action;

import java.io.File;

import org.apache.commons.io.FileUtils;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

private File upload;
private String uploadFileName;
public String getUploadFileName() {
return uploadFileName;
}
public void setUploadFileName(String uploadFileName) {
this.uploadFileName = uploadFileName;
}
public File getUpload() {
System.out.println(upload);
return upload;

}
public void setUpload(File upload) {
this.upload = upload;

}

public String execute() throws Exception {
String saveurl="d://文件上传";

if(upload!=null){
File file=new File(new File(saveurl),uploadFileName);
//这行是new了个文件然后保存文件的资源定位和名字
if (file.getParentFile().exists())
//获取要上传的文件
file.getParentFile().mkdirs();
//获取上传的文件并且新一个文件目录
FileUtils.copyFile(upload, file);
//复制要上传的文件
ActionContext.getContext().put("msg", "KO");
return "success";
}else {

return "error";
}
}
}
配置jsp
1.login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<s:form action="xiaobai" enctype="multipart/form-data">
<s:file name="upload"></s:file>
<s:submit value="提交"/>
</s:form>
</body>
</html>

2.success.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
${msg }
</body>
</html>
