[java] URL 파일 내용 읽기

은근 자주 쓰는데, 할때 마다 헷갈리고, 찾아본다..

public void readUrlFile(String url) {
   StringBuffer sb = new StringBuffer();
   BufferedReader in = null;
   try {
      in = new BufferedReader(new InputStreamReader(new URL(url).openStream()));
      String inputLine;
      while((inputLine = in.readLine()) != null) {
         sb.append(inputLine+"\n");
      }
      in.close();
   } catch (Exception e) {
      System.out.println("error:"+e.getMessage());
   } finally {
      if( in != null) {
         try {
            in.close();
         }catch (IOException ie){}
      }
   }
   System.out.println(sb.toString());
}
