springboot Redis 支持星号(*) 包括注解@Cache

通过自定义CacheManager Bean来实现

bean

   @Autowiredprivate RedisConnectionFactory redisConnectionFactory;/*** 管理缓存** @return*///缓存管理器@Primary@Bean@Overridepublic CacheManager cacheManager() {// 使用自定义的缓存配置初始化一个cacheManagerreturn new CustomizedRedisCacheManager(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory), redisCacheConfiguration());}
