Two. Register a REDIS message listener class

@Configuration Public classRedissublistenerconfig {//different channel names    Private Static FinalString channel = "Testchannel"; Private Static FinalString Channel2 = "Chat"; /*** REDIS Message Listener container * Can add multiple Redis listeners listening to different topics, only need to bind the message listener and the corresponding message subscription processor, the message listener * through the Reflection Technology call message subscription processor related methods for some business processing * @paramConnectionFactory *@paramListenerAdapter *@return     */@Bean//equivalent to a bean in XMLredismessagelistenercontainer Container (redisconnectionfactory connectionfactory, Messagelisteneradapter listeneradapter,messagelisteneradapter listenerAdapter2) {Redismessagelistenerco Ntainer Container=NewRedismessagelistenercontainer ();        Container.setconnectionfactory (ConnectionFactory); //subscribed to a channel called Testchannel.Container.addmessagelistener (ListenerAdapter,Newpatterntopic (Redissublistenerconfig.channel)); //subscribed to a channel called chatContainer.addmessagelistener (ListenerAdapter2,Newpatterntopic (Redissublistenerconfig.channel2)); returncontainer; }    /*** Message Listener adapter, binding message Processor, invoking the message processor's business method using reflection technology *@paramReceiver *@return     */@Bean messagelisteneradapter listeneradapter (messagereceiver receiver) {return NewMessagelisteneradapter (receiver, "ReceiveMessage"); } @Bean messagelisteneradapter ListenerAdapter2 (messagereceiver receiver) {return NewMessagelisteneradapter (receiver, "ReceiveMessage2"); }    /**template for Redis read content*/@Bean stringredistemplate Template (redisconnectionfactory connectionfactory) {return Newstringredistemplate (connectionfactory); }}

Three · Writing classes that handle subscription messages

@Component  Public class messagereceiver {     /** method for receiving Messages */public    void  ReceiveMessage (String message) {        System.out.println ("received a message:" +message);    }         /** methods for receiving messages */     Public void receiveMessage2 (String message) {        System.out.println ("received a message 2:" +message);}    }

Four. Start the program and send messages to the Redis chat and Testchannel channels to hear
