文件上传
action

1、创建表单―index.jsp

<li>测试struts上传文件</li><br>

      <form action="upload.do" method="post" enctype="multipart/form-data">

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

          文件：<input type="file" name="myfile"><br>

          <input type="submit" value="提交">

      </form>

2、上传成功文件―upload_success.jsp

<%@ page language="java" contentType="text/html; charset=GB18030"

    pageEncoding="GB18030"%>

<!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=GB18030">

<title>Insert title here</title>

</head>

<body>

<!-- 

    uploadForm.title中的uploadForm是根据

    <form-bean name="uploadForm" type="com.bjsxt.struts.UploadActionForm"/>

    中的name="uploadForm"而来的

-->

    标题：${uploadForm.title}<br>

    文件名：${uploadForm.myfile.fileName  }<br>

</body>

</html>

3、 UploadActionForm.java文件

package com.bjsxt.struts;

import org.apache.struts.action.ActionForm;

import org.apache.struts.upload.FormFile;

/**

 * 上传ActionForm

 * @author Administrator

 */

public class UploadActionForm extends ActionForm {

    private String title;

    //必须采用FormFile声明

    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;

4、 UploadTestAction.java文件

package com.bjsxt.struts;

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;

/**

 * 上传Action

 * @author Administrator

 */

public class UploadTestAction extends Action {

    @Override

    public ActionForward execute(ActionMapping mapping, ActionForm form,

            HttpServletRequest request, HttpServletResponse response)

            throws Exception {

        UploadActionForm uaf = (UploadActionForm)form;

        System.out.println("title" + uaf.getTitle());

        //FormFile是一个接口

        FormFile myFile = uaf.getMyfile();

        if (myFile != null) {

            System.out.println("fileName=" + myFile.getFileName());

            //存在C盘

            FileOutputStream fos = new FileOutputStream("c:\\" + myFile.getFileName());

            fos.write(myFile.getFileData());

            fos.flush();

            fos.close();

        return mapping.findForward("success");

5、配置struts-config.xml文件

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC

          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"

          "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

<struts-config>

        <form-bean name="uploadForm" type="com.bjsxt.struts.UploadActionForm"/>        

<action path="/upload"

                type="com.bjsxt.struts.UploadTestAction"

                name="uploadForm"

                scope="request"

            <forward name="success" path="/upload_success.jsp"/>

        </action>

</struts-config>

在struts-config.xml文件---配置上传文件的参数（采用<controller>标签）

・如上传文件的最大为10M，其他配置参数见struts.jar文件中的org.apache.struts.resources中的struts-config_1_2.dtd查看其他的参数

<controller maxFileSize="10M"/>

・struts-config_1_2.dtd中的可配置的信息

bufferSize className contentType forwardPattern nputForward locale maxFileSize memFileSize multipartClass nocache pagePattern processorClass tempDir
