org.apache.commons.logging.* JAR包
org.apache.struts.action.*; JAR包
org.apache.struts.config.* JAR包
以上三个JAR包去哪里下载？我要导入进去。谢谢

里面有 struts1 struts2 等许多开源软件你要的文件在 struts 包里就有参考技术A Apache的官网参考技术B struts的官网

struts1 & jquery form 文件异步上传

1.概述

还在用struts1？是的，在地球的没写地方，落后的生产方式还在运转(老项目).

从继承org.apache.struts.action.Action，继承org.apache.struts.action.ActionForm开始吧

2. 代码

2.1 html页面

<html>
<head>
<title>网页上传</title>
</head>
<body>
    <center>
        <h1>本地文件网页上传</h1>
        <hr>

    </center>

    <h1>文件信息列表</h1>
    <hr>
    <form  id="myform" method="post" enctype="multipart/form-data">
        <table width="0" border="0" cellspacing="10" cellpadding="0">
        
            <tr>
                <td>选择文件：</td>
                <td><input type="file" name="uploadFile" /></td>
            </tr>
            <tr>
                <td>标题：</td>
                <td><input type="text" name="filetitle" /></td>
            </tr>

            <tr>
                <td colspan="2">
                    <input type="button" id="mysubmit" value="确认上传"/>
                </td>
            </tr>

        </table>
    </form>
    <script src="script/jquery.js"></script>
    <script src="script/jquery.form.js"></script>
    <script src="script/_fileUpload.js"></script>
</body>
</html>

2.2 _fileUpload.js

/**
 *_fileUpload.js 
 *
 * 
 */
window.onload = function() {
    
    
    $("#mysubmit").bind("click", function(){
        $("#myform").ajaxSubmit({
            url: "myUpload.do",
            type: "post",
            success: function(data){
                console.log(11111111);
                console.log(data);
            },
            error: function(responseError){
                console.log(22222222222);
                console.log(responseError);
            }
            
        });
    });
}

2.3 MyUploadAction.java(继承自Action)

package com.rocky.console.action;

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

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 com.rocky.console.form.MyUploadForm;
import com.rocky.console.service.ResponseUtil;


public class MyUploadAction extends Action {

    
    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
            HttpServletResponse response) throws Exception{
        
        MyUploadForm myUploadForm = (MyUploadForm) form;
        FormFile uploadFile = myUploadForm.getUploadFile();
        String filetitle = myUploadForm.getFiletitle();
        System.out.println("111111"+filetitle);
        
        int fileSize = uploadFile.getFileSize();
        InputStream inputStream = uploadFile.getInputStream();
        System.out.println("fileSize::::::::"+fileSize);
        String path = "x:";
        String filename = path + File.separator + uploadFile.getFileName();
        FileOutputStream fos = new FileOutputStream(filename);
        byte[] b = new byte[1024];
        int len = -1;
        while((len = inputStream.read(b))!=-1){
            fos.write(b, 0, len);
        }
        fos.close();
        String result = "success";
        ResponseUtil.write(response, result, null);
        return null;
        
    }
}

2.4 MyUploadForm.java( 继承自ActionForm)

package com.rocky.console.form;

import javax.servlet.http.HttpServletRequest;

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

public class MyUploadForm extends ActionForm {

    /**
     * 
     */
    private static final long serialVersionUID = 6650496540449458586L;
    
    private FormFile uploadFile = null;
    
    private String filetitle;
    
    public String getFiletitle() {
        return filetitle;
    }

    public void setFiletitle(String filetitle) {
        this.filetitle = filetitle;
    }

    public ActionErrors validate(ActionMapping mapping,
            HttpServletRequest request) {
        return null;
    }
    
    public void reset(ActionMapping mapping, HttpServletRequest request) {
    }

    public FormFile getUploadFile() {
        return uploadFile;
    }

    public void setUploadFile(FormFile uploadFile) {
        this.uploadFile = uploadFile;
    }

}

2.5 struts-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "struts-config_1_2.dtd">

<struts-config>
    <data-sources />
    <form-beans>
        <form-bean name="myUploadForm" type="com.rocky.console.form.MyUploadForm" />
    </form-beans>
    <global-exceptions />
    <global-forwards />
    <action-mappings>
        <!-- rocky myupload -->
        <action path="/myUpload" attribute="myUploadForm" name="myUploadForm" type="com.rocky.console.action.MyUploadAction" />
    </action-mappings>
    <message-resources parameter="ApplicationResources" />
</struts-config>

2.6 说明

2.6.1 jquery.form.js 网上可以下载 http://malsup.com/jquery/form/#download

使用var formData = new FormData(), 然后formData.append("myfile", document.getElementById("myfile").files[0]);form.append...

当form表单field较多时写很多 append很麻烦，显然 ajaxSubmit方便很多

2.6.2 前端过来的数据通过 ActionForm 直接封装到其子类(MyActionForm)对象中 , 用FormFile接收file文件用String等接收其他类型数据

当然都是根据HTML 标签的name属性一一对应来注入的

2.6.3 ActionForm是怎么和自定义实现的bean(MyUploadForm) 对上的？

在struts-config.xml中form-bean设置自己的那个bean，通过<action path="/myUpload" attribute="myUploadForm" name="myUploadForm"

来完成这种映射
