public static void main(String[] args) {        HttpClient client = new HttpClient();
        PostMethod httpGet = new PostMethod(REMOTE_FILE_URL);
        try {
            client.executeMethod(httpGet);            InputStream in = httpGet.getResponseBodyAsStream();
            
            FileOutputStream out = new FileOutputStream(new File("E:\\GB-T 1.1-2000.pdf"));            byte[] b = new byte[BUFFER];
            int len = 0;
            while ((len = in.read(b)) != -1) {
                out.write(b, 0, len);
                out.flush();//注意要清空流
            }        } catch (HttpException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try{
             in.close();
            }catch(Exception e){
             e.printStackTrace();
            }
            try{
             out.close();
            }catch(Exception e){
             e.printStackTrace();
            }            
            httpGet.releaseConnection();
        }
        System.out.println("download, success!!");
    }
