读取远程文件，然后在指定目录下生成同样的文件

private void FileWrite(String ftp,String DXBS,String fileName,String fileExt){
         java.net.URL urlfile = null;
         HttpURLConnection httpUrl = null;

        try {

            // 连接指定的网络资源,获取网络输入流
             urlfile = new java.net.URL(ftp+"/"+DXBS+"/"+fileName+"."+fileExt);
             httpUrl = (HttpURLConnection) urlfile.openConnection();
             httpUrl.connect();
            int bytesum = 0;
            int byteread = 0;
             InputStream inStream = httpUrl.getInputStream();
            this.mkdir("d:/ftp/"+DXBS);
             FileOutputStream fs = new FileOutputStream("D:/ftp/"+DXBS+"/"+fileName+"."+fileExt);
            byte[] buffer = new byte[1444];
            while ((byteread = inStream.read(buffer)) != -1) {
                 bytesum += byteread;
                 fs.write(buffer, 0, byteread);
             }
         } catch (Exception e) {

         }
       
     }
   
     private void mkdir(String mkdirName) throws Exception {

         File dirFile = new File(mkdirName);
        boolean bFile = dirFile.exists();
        if (bFile == true) {
         } else {
             bFile = dirFile.mkdir();
            if (bFile == true) {
             } else {
                 System.exit(1);
             }
         }

     }      大家看代码，第一个方法是读取远程的文件，生成同样的目录文件，下面的方法是生成文件夹，想必这个大家应该都能清楚明了。
