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
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
