Spring boot integrates redis to implement shiro distributed session sharing, redisshiro We know that shiro manages sessions through SessionManager, while Session operations are implemented through SessionDao. By default, shiro implements two kinds of SessionDao, the two are CachingSessionDAO and MemorySessionDAO. When we use the EhCache cache, The CachingSessionDAO is used. If the cache is not applicable, t
