java http file copy....참 쉽죠잉

import java.io.File;

import java.io.FileOutputStream;

import java.net.URL;

 

import org.apache.commons.io.IOUtils;

 

String httpUrl = "";

URL url = new URL(httpUrl);

java.net.URLConnection connection = url.openConnection();

String fileName = dir+File.separator+result.getString("attachFileName", i);

IOUtils.copy(connection.getInputStream(), new FileOutputStream(fileName));
