我是靠谱客的博主受伤寒风，最近开发中收集的这篇文章主要介绍使用struts进行文件上传，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

Struts下进行文件上传。

配置文件如下内容：

<form-bean name="uploadForm" type="com.lwf.struts.action.upload.UploadForm"></form-bean>

<action path="/upload/upload" type="com.lwf.struts.action.upload.UploadAction" name="uploadForm">
	<forward name="success" path="/upload/uploadsuccess.jsp"></forward>
</action>

<controller maxFileSize="10m"/>

上面的controller 标签用来配置上传文件的最大值。

上传的表单文件upload.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@ include file="/share/jsp_head_include.jspf" %>
<!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>
<form name="uploadForm" action="upload.do" enctype="multipart/form-data" method="post">
	title:<input type="text" name="title"></input><br>
	file:<input type="file" name="myfile"></input><br>
	<input type="submit" value="submit"></input><br>
</form>
</body>
</html>

AcitonForm文件：UploadForm

package com.lwf.struts.action.upload;

import org.apache.struts.action.ActionForm;
import org.apache.struts.upload.FormFile;

public class UploadForm extends ActionForm {

	private String title;
	private FormFile myfile;
	
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public FormFile getMyfile() {
		return myfile;
	}
	public void setMyfile(FormFile myfile) {
		this.myfile = myfile;
	}
}

UploadAction文件

package com.lwf.struts.action.upload;

import java.io.File;
import java.io.FileOutputStream;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.upload.FormFile;
import org.apache.struts.upload.MultipartRequestHandler;

public class UploadAction extends Action {

	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		
		UploadForm uploadForm = (UploadForm)form;
		
		String title = uploadForm.getTitle();
		MultipartRequestHandler handler = uploadForm.getMultipartRequestHandler();
		FormFile myFile = uploadForm.getMyfile();
		if(myFile!=null){
			String fileName = myFile.getFileName();
			byte[] byteArray = myFile.getFileData();
			FileOutputStream fos = new FileOutputStream(new File("c:/" +fileName));
			fos.write(byteArray);
			fos.flush();
			fos.close();
		}
		return mapping.findForward("success");
	}

}

uploadsuccess.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>
upload sucess.

标题：${uploadForm.title }
文件名：${uploadForm.myfile.fileName }
</body>
</html>

注意的地方：

在Form中，使用了FormFile类型专门接收文件类型
