全部异常如下

Exception in thread "main" redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.
 at redis.clients.jedis.Protocol.processError(Protocol.java:127)
 at redis.clients.jedis.Protocol.process(Protocol.java:161)

 at redis.clients.jedis.Connection.getStatusCodeReply(Connection.java:239)
 at redis.clients.jedis.BinaryJedis.ping(BinaryJedis.java:196)
 at redis.main(redis.java:9)
错误原因：这是一个有密码的redis，你需要输入密码，最简单的连接如下
import redis.clients.jedis.Jedis;
public class redis {
    public static void main(String[] args) {
        //连接本地的 Redis 服务
        Jedis jedis = new Jedis("redis的ip",6379);
        //设置密码
        jedis.auth("123456");
        System.out.println("连接成功");
        //查看服务是否运行
        System.out.println("服务正在运行: "+jedis.ping());
    }
}
