Spring Boot使用Redis進行消息的發佈訂閱

1.application.properties配置redis以及連接池

spring.redis.host=123.207.115.129
spring.redis.password=198568huiqing
spring.redis.database=0
spring.redis.port=6379

3.redis消息監聽器容器配置

 */

@Configuration
@EnableCaching
public class RedisConfig{

	/**
	 * Redis消息監聽器容器
	 * @param connectionFactory
	 * @param listenerAdapter
	 * @return
	 */
	@Bean
	RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory, MessageListenerAdapter listenerAdapter) {

		RedisMessageListenerContainer container = new RedisMessageListenerContainer();
		container.setConnectionFactory(connectionFactory);
		//訂閱了一個叫pmp 的通道
		container.addMessageListener(listenerAdapter,new PatternTopic("pmp"));
		//這個container 可以添加多個 messageListener
		return container;
	}

	/**
	 * 配置消息接收處理類
	 * @param redisMsgSub  自定義消息接收類
	 * @return
	 */
	@Bean
	MessageListenerAdapter listenerAdapter(RedisMsgSub redisMsgSub) {
		//這個地方 是給messageListenerAdapter 傳入一個消息接受的處理器，利用反射的方法調用“receiveMessage”
		//也有好幾個重載方法，這邊默認調用處理器的方法 叫handleMessage 可以自己到源碼裏面看
		return new MessageListenerAdapter(redisMsgSub, "receiveMessage");
	}

}

4.redis消息接收

/**
 * <p>
 * Title:RedisMsgSub
 * </p>
 * <p>
 * Description:自定義消息接收類
 * </p>
 * <p>
 * Copyright:Copyright(c)2005
 * </p>
 * <p>
 * Company:skycomm.com.cn
 * </p>
 * <p>
 * Author:lishuangjiang
 * </p>
 * <p>
 * Date:2018/4/18 13:47
 * </p>
 */
@Component
public class RedisMsgSub{

    /**
     * 接收消息的方法
     * @param message 訂閱消息
     */
    public void receiveMessage(String message){
        System.out.println(message);
    }
}

5.redis消息多個訂閱不同的實現  代碼改造

    

    5.1添加redis訂閱消息接口

/**
 * <p>
 * Title:RedisMsg
 * </p>
 * <p>
 * Description:TODO
 * </p>
 * <p>
 * Copyright:Copyright(c)2005
 * </p>
 * <p>
 * Company:skycomm.com.cn
 * </p>
 * <p>
 * Author:lishuangjiang
 * </p>
 * <p>
 * Date:2018/4/18 17:18
 * </p>
 */
@Component
public interface RedisMsg {

    public void receiveMessage(String message);
}

    5.2實現消息接口

/**
 * <p>
 * Title:RedisPmpSub
 * </p>
 * <p>
 * Description:自定義消息接收類
 * </p>
 * <p>
 * Copyright:Copyright(c)2005
 * </p>
 * <p>
 * Company:skycomm.com.cn
 * </p>
 * <p>
 * Author:lishuangjiang
 * </p>
 * <p>
 * Date:2018/4/18 13:47
 * </p>
 */
public class RedisPmpSub implements RedisMsg{

    /**
     * 接收消息的方法
     * @param message 訂閱消息
     */
    public void receiveMessage(String message){
        System.out.println(message);
    }
}

5.2配置redis監聽容器

/**
 * <p>
 * Title:RedisConfig
 * </p>
 * <p>

 * </p>

 * Date:2018/4/18 13:47
 * </p>
 */
@Configuration
@EnableCaching
public class RedisConfig{
	/**
	 * Redis消息監聽器容器
	 * @param connectionFactory
	 * @return
	 */
	@Bean
	RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory) {

		RedisMessageListenerContainer container = new RedisMessageListenerContainer();
		container.setConnectionFactory(connectionFactory);
		//訂閱了一個叫pmp 的通道
		container.addMessageListener(listenerAdapter(new RedisPmpSub()),new PatternTopic("pmp"));
		container.addMessageListener(listenerAdapter(new RedisChannelSub()),new PatternTopic("channel"));
		//這個container 可以添加多個 messageListener
		return container;
	}

	/**
	 * 配置消息接收處理類
	 * @param redisMsg  自定義消息接收類
	 * @return
	 */
	@Bean()
	@Scope("prototype")
	MessageListenerAdapter listenerAdapter(RedisMsg redisMsg) {
		//這個地方 是給messageListenerAdapter 傳入一個消息接受的處理器，利用反射的方法調用“receiveMessage”
		//也有好幾個重載方法，這邊默認調用處理器的方法 叫handleMessage 可以自己到源碼裏面看
		return new MessageListenerAdapter(redisMsg, "receiveMessage");
	}
