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。
