RedisCluster 怎么使用连接池

Redis Cluster 是 Redis 的分布式解决方案，连接池可以有效地减少 Redis Cluster 的连接开销，提高应用程序的性能和可靠性。下面是 Redis Cluster 如何使用连接池的一些示例代码：

1. 使用 Jedis 连接池

JedisPoolConfig poolConfig = new JedisPoolConfig();
poolConfig.setMaxTotal(100);
poolConfig.setMaxIdle(50);
poolConfig.setMinIdle(10);
poolConfig.setMaxWaitMillis(3000);
poolConfig.setTestOnBorrow(true);
poolConfig.setTestOnReturn(true);

Set<HostAndPort> jedisClusterNodes = new HashSet<>();
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7000));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7001));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7002));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7003));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7004));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7005));

JedisCluster jedisCluster = new JedisCluster(jedisClusterNodes, poolConfig);

2. 使用 Lettuce 连接池

RedisClusterClient redisClusterClient = RedisClusterClient.create("redis://localhost:7000,redis://localhost:7001,redis://localhost:7002");
StatefulRedisClusterConnection<String, String> connection = redisClusterClient.connect();
RedisClusterCommands<String, String> syncCommands = connection.sync();

GenericObjectPoolConfig<StatefulRedisClusterConnection<String, String>> poolConfig = new GenericObjectPoolConfig<>();
poolConfig.setMaxTotal(100);
poolConfig.setMaxIdle(50);
poolConfig.setMinIdle(10);
poolConfig.setMaxWaitMillis(3000);
poolConfig.setTestOnBorrow(true);
poolConfig.setTestOnReturn(true);

RedisClusterClientPool clientPool = new RedisClusterClientPool(redisClusterClient, poolConfig);
StatefulRedisClusterConnection<String, String> connection = clientPool.borrowObject();
RedisClusterCommands<String, String> syncCommands = connection.sync();
clientPool.returnObject(connection);

这些示例代码都是使用连接池来管理 Redis Cluster 的连接，可以根据具体情况进行调整。
