springcloud redis集群怎么配置

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：

    org.springframework.boot
    spring-boot-starter-data-redis

2. 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

3. 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 redisTemplate(JedisConnectionFactory jedisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(jedisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        return redisTemplate;
    }

    @Bean
    public RedisCacheManager redisCacheManager(RedisTemplate redisTemplate) {
        RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);
        redisCacheManager.setUsePrefix(true);
        return redisCacheManager;
    }
}

4. 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 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。
