Question

我正在设置一个服务器，该服务器可以侦听和发送有关Redis数据库中发生的任何事件的消息。我成功地获得了有关Redis主机和端口的新事件的通知，但未能针对Redis集群发出通知。

GenericObjectPoolConfig config = new GenericObjectPoolConfig();
        config.setMaxTotal(30);
        config.setMaxWaitMillis(2000);

        Set<HostAndPort> jedisClusterNode = new HashSet<HostAndPort>();
        jedisClusterNode.add(new HostAndPort("127.0.0.1", 7001));

        JedisCluster cluster1 = new JedisCluster(jedisClusterNode, config);

        String redisProperties = cluster1.getClusterNodes().toString().replaceAll("[{}]", "");
        Set<HostAndPort> nodes = new HashSet<>();
        String[] mainArray = redisProperties.split(",");
        for (int i = 0; i < mainArray.length; i++) {
            String[] equalArray = mainArray[i].split("=");
            String mainData = equalArray[0];
            String[] ipPortPair = mainData.split(":");
            nodes.add(new HostAndPort(ipPortPair[0].trim(), Integer.valueOf(ipPortPair[1].trim())));
        }

        JedisCluster cluster = new JedisCluster(nodes, 10000, 1000, 1, config);

jedis.configSet（“ notify-keyspace-events”，“ AKE”）; //对于所有类型的事件 jedis.psubscribe（new KeyListenerCluster（），“ keyevent @ 0 ：*”）;

在使用redis-cluster时，我能够执行所有其他操作，但不能做一件事。

cluster.configSet（“ notify-keyspace-events”，“ AKE”）; //对于所有类型的事件 cluster.psubscribe（new KeyListenerCluster（），“ keyevent @ 0 ：*”）;

我遇到了同样的问题，“键空间”通知间歇性地工作（10次中有6次或7次）。我读到一个需要订阅所有主节点才能获得通知。如果有帮助，我可以在下面粘贴我的配置文件：

KeySpaceNotificationMessageListener keySpaceNotificationMessageListener;

    @Value("${spring.redis.cluster.nodes}")
    private String hostsAndPorts;

    @Bean
    JedisConnectionFactory jedisConnectionFactory(RedisClusterConfiguration redisClusterConfiguration)
    {
        return new JedisConnectionFactory(redisClusterConfiguration);
    }

    @Bean
    MessageListenerAdapter messageListener() {
        return new MessageListenerAdapter(keySpaceNotificationMessageListener);
    }


    @Bean(name = "cacheManager1")
    @Primary
    public RedisCacheManager redisCacheManager1()
    {
        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .disableCachingNullValues()
                .entryTtl(Duration.ofMinutes(1))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.json()));

        redisCacheConfiguration.usePrefix();

        return RedisCacheManager.RedisCacheManagerBuilder.fromConnectionFactory(jedisConnectionFactory(redisClusterConfiguration()))
                .cacheDefaults(redisCacheConfiguration).build();

    }

    @Bean(name = "cacheManager2")
    public RedisCacheManager redisCacheManager2( JedisConnectionFactory jedisConnectionFactory)
    {
        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                .disableCachingNullValues()
                .entryTtl(Duration.ofDays(1))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.json()));

        redisCacheConfiguration.usePrefix();

        return RedisCacheManager.RedisCacheManagerBuilder.fromConnectionFactory(jedisConnectionFactory(redisClusterConfiguration()))
                .cacheDefaults(redisCacheConfiguration).build();

    }

    @Bean
    public RedisClusterConfiguration redisClusterConfiguration()
    {
        String [] redisHostAndPorts = hostsAndPorts.split(",");

        System.out.println(Arrays.toString(redisHostAndPorts));
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(Arrays.asList(redisHostAndPorts));
        return redisClusterConfiguration;
    }

    @Bean
    RedisMessageListenerContainer redisContainer() {
        final RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(jedisConnectionFactory(redisClusterConfiguration()));
        container.addMessageListener(messageListener(), new PatternTopic("__keyspace@*:*"));
        container.setTaskExecutor(Executors.newFixedThreadPool(4));
        return container;
    }

    public void setKeySpaceNotificationMessageListener(KeySpaceNotificationMessageListener keySpaceNotificationMessageListener)
    {
        this.keySpaceNotificationMessageListener = keySpaceNotificationMessageListener;
    }

如何使用Jedis Client监听Java中Redis集群的键空间通知？
