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

3. 乱码问题

当form表单field值为中文上面的代码会出现乱码

解决方案

3.1 js部分加上 contentType: "application/x-www-form-urlencoded; charset=utf-8",

/**

3.2 ActionForm的实现类重写reset方法

    public void reset(ActionMapping mapping, HttpServletRequest request) {

        try {

            request.setCharacterEncoding("utf-8");

        } catch (Exception e) {

        }

    }

        Uploadinfo uploadinfo = new Uploadinfo();

        uploadinfo.setUploadtime(uploadtime);

        uploadinfo.setUploadCompany(uploadCompany);

        uploadinfo.setUploader(uploader);

        uploadinfo.setTelephone(telephone);

        uploadinfo.setEventTitle(eventTitle);

        uploadinfo.setEventTime(eventTime);

        uploadinfo.setEventPlace(eventPlace);

        uploadinfo.setManAndEvent(manAndEvent);

        uploadinfo.setInterviewee(interviewee);

        uploadinfo.setPositionTitle(positionTitle);

        uploadinfo.setDataSource(dataSource);

        uploadinfo.setKeyword(keyword);

        uploadinfo.setDataDescription(dataDescription);

        return uploadinfo;

    }

}

3.4 另外在网上看到源码解决方案记录一下

在包org.apache.struts.upload下，有一个类CommonsMultipartRequestHandler，它主要负责文件上传处理，
它使用的是DiskFileUpload来上传文件， DiskFileUpload upload = new DiskFileUpload();它的默认编码为ISO-8859-1，

因此对中文处理有乱码，可以在此修改它的编码：upload.setHeaderEncoding("utf8");
