upload.jsp实现如下:
<%@ page contentType="text/html;charset=GBK" %>
<%@ page import="java.io.*"%>
<%@ page import="java.util.*"%>
<%@ page import="javazoom.upload.*"%>
<%@ page import="uploadutilities.FileMover"%>
<%@ page import="java.text.SimpleDateFormat"%>
<%
request.setCharacterEncoding("GBK");//设置编码格式，就不用一个个转码了。
FileMover fileMover = new FileMover();//你也可以使用自带的实例中jsp:useBean的形式。
UploadBean upBean = new UploadBean();
MultipartFormDataRequest mrequest = null;
Hashtable files = null;
if(MultipartFormDataRequest.isMultipartFormData(request)){
try{
mrequest = new MultipartFormDataRequest(request,null,10*1024*1024,MultipartFormDataRequest.COSPARSER,"GBK");//注意这里也要设置编码参数
files = mrequest.getFiles();
}catch(IOException e){
%>
<script language="javascript">
alert("请上传小于10M的文件");
history.back(-1);
</script>
<%
}
}
String sServerFileName=""; //服务器文件名
String sLocalFileName = ""; //本地文件名
if(files!=null && !files.isEmpty()){
UploadFile file=null;
String examName=mrequest.getParameter("examName");
String introduce=mrequest.getParameter("introduce");
OnlineTestServiceImpl epsi=new OnlineTestServiceImpl();
file = (UploadFile) files.get("uploadfile");
sLocalFileName=file.getFileName();
int ii= sLocalFileName.indexOf("."); //取文件名的后缀
String sExt = sLocalFileName.substring(ii,sLocalFileName.length());
//得到不重复的文件名
java.util.Date dt = new java.util.Date(System.currentTimeMillis());
SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMddHHmmssSSS");
sServerFileName= fmt.format(dt);
sServerFileName =sServerFileName + sExt;
ExcelReader readExcel = new ExcelReader();
File dir =new File("D:\\test1");
if (!dir.exists()){
dir.mkdirs();
}
upBean.setFolderstore("D:\\test1");//设置要上传的目录
upBean.addUploadListener(fileMover);//增加filMover监听
fileMover.setNewfilename(sServerFileName);//设置服务器上的文件名
upBean.store(mrequest, "uploadfile");//上传
}
}
