// 创建post请求方法实例对象

return result;

}

public static String sendGet(String urlParam) throws HttpException, IOException {

return result;

}

public static void main(String[] args) throws HttpException, IOException {

String url = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip=120.79.75.96";

System.out.println(sendPost(url));

System.out.println(sendGet(url));

}

}

会出现一些没用的日志 设置日志的输出等级就OK了

logging.level.root=error
