Java实现模拟QQ空间图片上传
首先编写我们的上传jsp代码，如下:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Java实现开发QQ空间上传</title>
<style type="text/css">
body{background: url("image/bg_webp.jpg");}
*{padding: 0px;margin: 0px;}
.qq{width: 520px;height: 70px;margin: 200px auto;border: 1px solid #e6e6e6;background-color: #fff}
.qq .qq_pic{float: right;width: 48px;height: 70px;border-left: 1px solid #eee8d1;background-color: #fafafa;border-right: 1px solid #eee8d1 }
.qq .qq_pic .bg_button{width: 48px;height: 70px;display: block;padding: 20px 0px 0px 10px}
.qq .qq_pic .bg_button:HOVER{background-color: #fff;height: 50px;width: 38px;}
.qq .qq_pic .bg_button i{background: url("image/bg_button.png");background-position: -490px -125px;width: 25px;height: 25px;display: block;}
.qq .qq_pic input{display: none;}
</style>
</head>
<body>
<form action="<%=request.getContextPath()%>/UploadQQServlet" enctype="multipart/form-data" method="post" id="saveForm">
<div class="qq">
<div class="qq_pic">
<a href=http://www.mamicode.com/"#" class="bg_button" onclick="openBrowser()">>
然后编写我们的后台代码，这里我就简单使用Servlet
package com.wonders.upload;
import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;
import java.util.UUID;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class UploadQQServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
//获取文件路径
String strPath=request.getRealPath("/")+"/upload";
File file =new File(strPath);
if(!file.exists())file.mkdirs();
FileItemFactory factory=new DiskFileItemFactory();
ServletFileUpload upload=new ServletFileUpload(factory);
//从请求对象中获取文件信息
List items;
try {
items = upload.parseRequest(request);
if(items!=null){
for(int i=0;i<items.size();i++){
Iterator iterator=items.iterator();
while(iterator.hasNext()){
FileItem item=(FileItem)iterator.next();
if(item.isFormField()){
continue;
}else{
String fileName=item.getName();
Long fileSize=item.getSize();
int pos=fileName.indexOf(".");
String ext=fileName.substring(pos,fileName.length());
fileName=UUID.randomUUID().toString()+ext;
request.getSession().setAttribute("fileName", fileName);
File saveFile=new File(strPath,fileName);
item.write(saveFile);
response.sendRedirect("UploadQQ.jsp");
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
ok,此代码联手而用！下载源码:http://download.csdn.net/detail/u010506940/8401307
