注册订阅类

public class MessageReceiver {

	/**接收消息的方法*/
	public void receiveMessage(String message){
		System.out.println("收到一条消息："+message);
	}
}

	@Bean
	public MessageReceiver messageReceiver(){

		return new MessageReceiver();
	}

	@Bean
	public MessageListenerAdapter messageListenerAdapter(MessageReceiver messageReceiver){

		return new MessageListenerAdapter(messageReceiver,"receiveMessage");
	}

	@Bean
	public RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,
	                                        MessageListenerAdapter listenerAdapter) {

		RedisMessageListenerContainer container = new RedisMessageListenerContainer();
		container.setConnectionFactory(connectionFactory);
		//订阅了一个叫chat 的通道
		container.addMessageListener(listenerAdapter, new PatternTopic("chat"));
		//这个container 可以添加多个 messageListener
		return container;
	}
