Springboot Connect Redis and dynamically switch database

Springboot Connect Redis and dynamically switch database

As we all know, Redis has a db, in the Jedis can use the Select method to dynamically select the Redis database, but in the stringredistemplate provided by Springboot does not have this method, Fortunately, stringredistemplate reserved a setconnectionfactory method, this article is to modify the connectionfactory so as to achieve dynamic switching database effect. springboot Connection Redis

        String TestKey = Stringstringvalueoperations.get ("TestKey");
        Logger.info (TestKey);
    }

Run Testcredis.t1 (), console print "TestValue" Redis connection successful redis dynamic switch Database

First, use REDIS-CLI to set the value of test in the 0, 1, 23 libraries of Redis, respectively 0, 1, 2

}

Run Testcredis.t2 (), the console prints "0, 1, 2", the database switch succeeded
