要配置Spring Cloud Redis集群,需要按照以下步骤进行配置:

  1. 在pom.xml文件中添加Redis相关的依赖:
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
  1. 在application.properties文件中配置Redis集群的连接信息:
# Redis集群节点信息
spring.redis.cluster.nodes=127.0.0.1:7001,127.0.0.1:7002,127.0.0.1:7003

# Redis连接池配置
spring.redis.cluster.max-idle=8
spring.redis.cluster.min-idle=1
spring.redis.cluster.max-active=8
spring.redis.cluster.max-wait=3000
  1. 创建Redis配置类,用于配置RedisTemplate和连接池:
@Configuration
public class RedisConfig {

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

    @Value("${spring.redis.cluster.max-idle}")
    private int maxIdle;

    @Value("${spring.redis.cluster.min-idle}")
    private int minIdle;

    @Value("${spring.redis.cluster.max-active}")
    private int maxActive;

    @Value("${spring.redis.cluster.max-wait}")
    private long maxWait;

    @Bean
    public RedisClusterConfiguration redisClusterConfiguration() {
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(Arrays.asList(clusterNodes.split(",")));
        return redisClusterConfiguration;
    }

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

    @Bean
    public RedisTemplate<String, Object> redisTemplate(JedisConnectionFactory jedisConnectionFactory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(jedisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        return redisTemplate;
    }

    @Bean
    public RedisCacheManager redisCacheManager(RedisTemplate<String, Object> redisTemplate) {
        RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);
        redisCacheManager.setUsePrefix(true);
        return redisCacheManager;
    }
}
  1. 在需要使用Redis的地方注入RedisTemplate,即可使用Redis集群进行操作:
@Autowired
private RedisTemplate<String, Object> redisTemplate;

public void set(String key, Object value) {
    redisTemplate.opsForValue().set(key, value);
}

public Object get(String key) {
    return redisTemplate.opsForValue().get(key);
}

public boolean exists(String key) {
    return redisTemplate.hasKey(key);
}

这样就完成了Spring Cloud中使用Redis集群的配置。需要注意的是,Redis集群的节点信息和连接池的配置可以根据实际情况进行修改。
