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：

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>

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=8spring.redis.cluster.min-idle=1spring.redis.cluster.max-active=8spring.redis.cluster.max-wait=3000

创建Redis配置类，用于配置RedisTemplate和连接池：

@Configurationpublic 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;@Beanpublic RedisClusterConfiguration redisClusterConfiguration() {RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(Arrays.asList(clusterNodes.split(",")));return redisClusterConfiguration;}@Beanpublic JedisConnectionFactory jedisConnectionFactory(RedisClusterConfiguration redisClusterConfiguration) {JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisClusterConfiguration);return jedisConnectionFactory;}@Beanpublic 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;}@Beanpublic RedisCacheManager redisCacheManager(RedisTemplate<String, Object> redisTemplate) {RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);redisCacheManager.setUsePrefix(true);return redisCacheManager;}}

在需要使用Redis的地方注入RedisTemplate，即可使用Redis集群进行操作：

@Autowiredprivate 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。
