SpringBoot集成redisCluster(redis集群)实现发布订阅、消息队列

SpringBoot+redisCluster封装RedisTemplate，通过RedisTemplate操作Redis,并简单的实现消息队列、发布订阅的功能；

首先导入Maven:

 <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
 </dependency>

在springboot的application.properties配置文件中配置redis集群的地址：

#redis
spring.redis.cluster.nodes=10.2.102.244:6379,10.2.102.244:6380,10.2.102.244:6381

下图是我的一个项目结构：

使用@Configuration注解初始化redisCluter配置，返回出一个封装后的RedisTemplate和一个JedisCluster对象用来操作我们redis集群和封装redis的操作命令：RedisCluterConfig类
