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
