来源：互联网发布：软件安全性测试过程编辑：程序博客网时间：2024/05/17 08:26

使用jquery点击添加按钮添加浏览框实现struts多文件上传。

例如：点击添加，添加一个浏览框。

Jsp页面代码：

<%@page language="java" import="java.util.*"pageEncoding="utf-8"%>

Stringpath = request.getContextPath();

StringbasePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<!DOCTYPEHTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>Untitled Document</title>

<scripttype="text/javascript" src="./js/jquery-1.7.1.js">

</script>

<scripttype="text/javascript">

$(function(){

var i = 2;

$("#add").click(function(){

$("#main").append(

'<div>上传文件：<inputtype="file" name="upload"/></div>');

});

</script>

</head>

<body>

<formaction="${pageContext.request.contextPath}/csdn/upFiles.action"

enctype="multipart/form-data"method="post">

<div>

上传文件：<input type="file"name="upload" />

</div>

</form>

</div>

</body>

</html>

UploadsAction代码：

packagecn.csdn.hr.up.action;

importjava.io.File;

importjava.io.IOException;

importorg.apache.commons.io.FileUtils;

importorg.apache.struts2.ServletActionContext;

importcom.opensymphony.xwork2.ActionSupport;

publicclass UploadsAction extends ActionSupport {

// 规定

private File upload[];// 上传文件

// 上传文件的类型

private String uploadContentType[];

// 上传文件的名称

private String uploadFileName[];

public File[] getUpload() {

return upload;

}

public void setUpload(File[] upload) {

this.upload = upload;

}

public String[] getUploadContentType() {

return uploadContentType;

}

public void setUploadContentType(String[]uploadContentType) {

this.uploadContentType =uploadContentType;

}

public String[] getUploadFileName() {

return uploadFileName;

}

public void setUploadFileName(String[]uploadFileName) {

this.uploadFileName = uploadFileName;

}

public String uploads() {

String path =ServletActionContext.getServletContext().getRealPath(

"/ims");

File file = new File(path);

if (!file.exists()) {

file.mkdirs();

}

/**

* 以流的方式读取文件写入到指定文件中去mkdirs mkdir区别 FileUtils工具完成上传

try {

for(int i=0;i<upload.length;i++){

FileUtils.copyFile(upload[i], newFile(file, uploadFileName[i]));

}

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

System.out.println("上传文件的名称:" +getUploadFileName() + "------上传文件的类型"

+ getUploadContentType());

return SUCCESS;

}
