是的，Spring Data Redis 可以連接到 Redis 集群。為了實現這一點，你需要使用 Spring Data Redis 的 RedisClusterConfiguration 類來配置集群連接。以下是一個簡單的示例，展示了如何配置 Spring Data Redis 以連接到 Redis 集群：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceClientConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.cluster.RedisClusterConfiguration;
import org.springframework.data.redis.core.cluster.lettuce.LettuceClusterConnectionFactory;

@Configuration
public class RedisConfig {

    @Bean
    public LettuceConnectionFactory redisConnectionFactory() {
        // 配置集群節點
        RedisStandaloneConfiguration standaloneConfig = new RedisStandaloneConfiguration();
        standaloneConfig.setHostName("node1");
        standaloneConfig.setPort(6379);
        standaloneConfig.setDatabase(0);

        // 配置集群連接工廠
        LettuceClientConfiguration clientConfig = LettuceClientConfiguration.builder()
                .commandTimeout(Duration.ofMillis(1000))
                .build();

        RedisClusterConfiguration clusterConfig = new RedisClusterConfiguration();
        clusterConfig.addClusterNode(standaloneConfig);
        clusterConfig.addClusterNode(new RedisStandaloneConfiguration().setHostName("node2").setPort(6380).setDatabase(0));
        clusterConfig.addClusterNode(new RedisStandaloneConfiguration().setHostName("node3").setPort(6381).setDatabase(0));

        LettuceClusterConnectionFactory clusterConnectionFactory = new LettuceClusterConnectionFactory(clusterConfig, clientConfig);

        return clusterConnectionFactory;
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory());
        return template;
    }
}

在這個示例中，我們配置了一個包含三個節點的 Redis 集群，并使用 Lettuce 作為客戶端連接工廠。RedisTemplate 用于簡化 Redis 操作。你可以根據你的實際需求修改節點配置。
