1．文件上传页面，其中包含两个表单域：文件标题和文件浏览域

- 程序功能：上传页面，包含两个表单域。
- 程序源码：

upload.html

<head>

<title>简单的文件上传</title>

</head>

<body>

文件标题：<input type="text" name="title" /><br>

选择文件：<input type="file" name="upload" /><br>

</form>

</body>

</html>

2．处理上传请求的Action类

程序源码：

UploadAction.java

package Action;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class UploadAction extends ActionSupport

{

private String title;

private File upload;

private String uploadContentType;

private String uploadFileName;

//接受依赖注入的属性

private String savePath;

//接受依赖注入的方法

public void setSavePath(String value)

{

this.savePath = value;

}

private String getSavePath() throws Exception

{

return ServletActionContext.getRequest().~~getRealPath~~(savePath);

}

public void setTitle(String title) {

this.title = title;

}

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 getTitle() {

return (this.title);

}

public File getUpload() {

return (this.upload);

}

public String getUploadContentType() {

return (this.uploadContentType);

}

public String getUploadFileName() {

return (this.uploadFileName);

}

@Override

public String execute() throws Exception

{

System.out.println("开始上传单个文件-----------------------");

System.out.println(getSavePath());

System.out.println("==========" + getUploadFileName());

System.out.println("==========" + getUploadContentType());

System.out.println("==========" + getUpload());

//以服务器的文件保存地址和原文件名建立上传文件输出流

FileOutputStream fos = new FileOutputStream(getSavePath() + "\\" + getUploadFileName());

FileInputStream fis = new FileInputStream(getUpload());

byte[] buffer = new byte[1024];

int len = 0;

while ((len = fis.read(buffer)) > 0)

{

fos.write(buffer , 0 , len);

}

return SUCCESS;

}

配置文件上传的Action

程序源码：

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">

<param name="savePath">/upload</param>

</action>

</package>

</struts>

Succ.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

上传成功 <br>

</body>

</html>
