Redis版本：3.2.0

Jedis版本：2.8.1

下面是我连接到redis的java代码：

public class TestRedis {

public static void main(String[] args) {

String host = args[0];

int port = Integer.parseInt(args[1]);

try (Jedis jedis = new Jedis(host, port)) {

System.out.println("Connected to jedis " + jedis.ping());

} catch(Exception e){

e.printStackTrace();

}

}

}

我在安装了redis的机器上运行此程序.这台机器的IP地址是192.168.1.57

如果我提供host =“localhost”和port =“6379”作为参数,则成功建立与redis的连接.

但是,如果我在参数中给出host =“192.168.1.57”和port =“6379”,我最终得到以下异常：
