方法一SmartUpload对象上传
用到jsmartcom_zh_CN.jar包
//用smartupload方法上传
package com.ruide.action;
import java.io.IOException;
import java.sql.SQLException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.jspsmart.upload.File;
import com.jspsmart.upload.Files;
import com.jspsmart.upload.SmartUpload;
import com.jspsmart.upload.SmartUploadException;
public class UploadSmart1Action extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
SmartUpload smart=new SmartUpload();
smart.initialize(this.getServletConfig(),request, response);
smart.setMaxFileSize(1024*1024*1024);
try {
smart.setDeniedFilesList("exe,bat,,");
} catch (SQLException e) {
e.printStackTrace();
}
try {
smart.upload();
} catch (SmartUploadException e) {
e.printStackTrace();
}
Files fs=smart.getFiles();////是个文件集合，得到所有文件
File f=fs.getFile(0);
String filename=f.getFileName();//原文件名
long times=System.currentTimeMillis();//系统当前时间
String newfilename=times+filename.substring(filename.indexOf("."));//系统当前时间+截取源文件名后获取后缀名
//System.out.println(newfilename);
//获取当前工程的路径名，加上新的文件名
String path=request.getRealPath("/files/");
path=path+"\\"+newfilename;
//保存文件
try {
f.saveAs(path);
} catch (SmartUploadException e) {
e.printStackTrace();
}
}
}
下面是jsp页面的测试
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'upload.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">

<body>
<form action="uploadsmart1" method="post" enctype="multipart/form-data">
<p>用户名：<input type="text" name="username" /></p>
<p>用户密码：<input type="password" name="userpass" /></p>
<p>上传照片：<input type="file" name="photo" value="浏览"/></p>
<p><input type="submit" value="提交"></p>
</form>
</body>
</html>
方法二ServletFileUpload对象上传，支持多文件上传
用到两个jar包：commons-fileupload-1.2.1.jar和commons-io-1.4.jar
package com.ruide.action;
import java.io.File;
import java.io.IOException;
import java.util.List;
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.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class CommonFileUpload1Action extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
this.doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try {
ServletFileUpload upload=new ServletFileUpload(new DiskFileItemFactory());
List<FileItem> list=upload.parseRequest(request);
for(int i=0;i<list.size();i++){
FileItem fi=list.get(i);
boolean iden=fi.isFormField();
if(iden){//处理普通文件
String name=fi.getFieldName();
String value=fi.getString("GBK");
}else{//处理文件
//文件的文件名
String name=fi.getName();////有的电脑得到的是文件名，有的电脑得到的是路径+文件名
name=name.substring(name.lastIndexOf("\\")+1);//处理出现第二种“路径+文件名”做到各个电脑或浏览器都兼容该上传方式
long times=System.currentTimeMillis();
String newname=times+name.substring(name.lastIndexOf("."));//时间+后缀的文件
String path=request.getRealPath("/files/");
File f=new File(path+"/"+newname);
fi.write(f);
}
}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}

<%

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