Redis Cluster Cache with SpringBoot
前提:
根据 https://www.cnblogs.com/luffystory/p/12081074.html
创建好Redis集群

RedisCacheManager 中使用 configMap 做如下 c1 和 redisCacheConfig 的mapping
configMap.put("c1" , redisCacheConfig);
如下
@Cacheable(value = "c1")
@Cacheable(vaule = "c2")
c1 存在于configMap 中,因此使用的缓存策略是 configMap 集合中 c1 所对应的缓存策略;
c2 不存在于 configMap 集合中,因此使用的缓存策略是默认的缓存策略。
RedisCacheManager redisCacheManager = new RedisCacheManager(cacheWriter,
RedisCacheConfiguration.defaultCacheConfig(), configMap);

代码配置好之后 run RedisClusterCacheApplicationTests as Junit Test, test 通过之后
可以看到方法的参数和返回值已被缓存到 Redis 中。
