So what are we going to do with a cache server in general? It's not exactly what you need. Oh, in general, it is necessary to read a field frequently when you

In MyBatis, developers are allowed to customize their own caches, and this article uses Redis as a level two cache for MyBatis. Defining a Level Two cache in MyBatis requires the following configuration:1, mybatis support the total switch of level two cache: Global configuration variable parameter "Cacheenabled=true"2.

Redis Cache Server NotesRedis is a high-performance key-value storage system that can serve as a caching framework and queueBut since he is a memory memory system, the data is stored in the database As a caching framework:create/updae/delete-at the same time to Redis and databasequery– first from the Redis, no records

Abstract: mainly for the DAO layer of some database query operation, the data is not strong real-time, directly into the cache. When it is in the cache, the data in the cache is used. Such a method is eventually implemented using only one annotation. For the previous Hibernate level two cache use, it is quite strange.

In fact, there is enterpriselibrary. caching is only a way to achieve cache persistence. redis, as a mature distributed storage middleware, is more handy in implementing this dataset
