swfupload+Struts2多文件上传
公司做了一个相册模块，其中有一个要用多文件上传，可是使用的是很老的单文件上传的模式，感觉使用不是很方便，于是在网上搜索了一下，搜到了swfupload这个上传组件，于是尝试着使用struts2整合swfupload写了写，现在把代码放上来。
一、起始页代码
二、upload.jsp
三、action文件
上传不上去的原因的是没有新建一个文件夹 upload
一、起始页代码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

二、upload.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<body>
<s:form action="PictureAction.action" enctype="multipart/form-data">
<s:file name="file"></s:file>
<s:submit></s:submit>
</s:form>
</body>
</html>
三、action文件
package com.action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import org.apache.struts2.ServletActionContext;
import com.model.Picture;
import com.opensymphony.xwork2.ActionSupport;
public class PictureAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
private File file;
private String fileFileName;
private String fileContentType;
public File getFile() {
return file;
}
public void setFile(File file) {
this.file = file;
}
public String getFileFileName() {
return fileFileName;
}
public void setFileFileName(String fileFileName) {
this.fileFileName = fileFileName;
}
public String getFileContentType() {
return fileContentType;
}
public void setFileContentType(String fileContentType) {
this.fileContentType = fileContentType;
}
/**
* 用于实现上传功能
*/
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
//实现上传
InputStream is = new FileInputStream(file);
String root = ServletActionContext.getRequest().getRealPath("/upload");
System.out.println(this.getFileContentType() );
File deskFile = new File(root,this.getFileFileName());
OutputStream os = new FileOutputStream(deskFile);
byte [] bytefer = new byte[400];
int length = 0 ;
while((length = is.read(bytefer) )>0)
{
os.write(bytefer,0,length);
}
os.close();
is.close();
return SUCCESS;
}
}
上传不上去的原因的是没有新建一个文件夹 upload
