上传文件名字问题？？

Question

is = cform.getImportfile().getInputStream();
            BufferedReader br=new BufferedReader(new InputStreamReader(is));
            String currdir = request.getSession().getServletContext()
                    .getRealPath("/")
                    + File.separator
                    + "page"
                    + File.separator
                    + "welcomePages"
                    + File.separator + df.format(new Date()) + fileName;
            File dir = new File(currdir);
            fs = new FileOutputStream(dir);
            PrintWriter pw=new PrintWriter(fs);
            pw.println("<%@ page contentType=\"text/html;charset=GB2312\"%>");
            String data = null;
            //一行行读取
            while((data = br.readLine())!=null)
            {
            pw.println(data);
            }
            pw.flush();
            pw.close();
            br.close();
            
+ File.separator + df.format(new Date()) + fileName;
File dir = new File(currdir);
fs = new FileOutputStream(dir);
PrintWriter pw=new PrintWriter(fs);因为fileName是html格式的，我要写入到就到jsp格式中 就是那个fs怎么处理？？？

Answer 1

fileName换成下面的即可
fileName.split("\\.")[0].toString()+".jsp";
