您如何订阅哨兵并从他们那里接收出版物？

Question

我正在尝试使用 pub/sub impl。在 Jedis 上获取有关 master 倒下的信息，但我不确定如何订阅 Sentinel 频道。

我的发布者class:

public Publisher(Jedis publisherJedis, String channels, String clusterName) {
    this.publisherJedis = publisherJedis;
    this.channels = channels;
    this.clusterName = clusterName;
}

public void start() {
    log.info("publishing on channel +odown");    
    try {
        while(true) {
            if(JedisPoolFactory.getMasterDown(clusterName)) {
                publisherJedis.publish("+odown", "master down, master down");
            }
        }
    } catch(Exception ex) {
        log.error("failure with end of stream catching.", ex);
    }
}

我必须将我的哨兵注册为发布者，我需要做的就是在每次发生主故障转移时解码消息。我该如何订阅 sentinel 频道？

Answer 1

正如antirez所说，您可以使用普通的Jedis实例连接到sentinel，并订阅频道。和Redis完全一样 pub/sub.
