1，RedisConfigContainer类读取redis配置信息 初始化StringRedisTemplate

import org.springframework.beans.factory.annotation.Value;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.data.redis.listener.ChannelTopic;
    import org.springframework.data.redis.listener.RedisMessageListenerContainer;
    import org.springframework.data.redis.listener.adapter.MessageListenerAdapter;
    import com.game.redis.container.MsgListener;
    
    /**
     * 配置默认Redis操作实例 到Spring中
     *
     */
    //@Component
    //@PropertySource("classpath:application-test.yml")
    //
    @Configuration
    @EnableCaching
    public class RedisConfigContainer extends RedisConfig {
    
    	@Value("${spring.redis.redis-container.database}")
    	private int dbIndex;
    
    	@Value("${spring.redis.redis-container.host}")
    	private String host;
    
    	@Value("${spring.redis.redis-container.port}")
    	private int port;
    
    	@Value("${spring.redis.redis-container.password}")
    	private String password;
    
    	@Value("${spring.redis.redis-container.timeout}")
    	private int timeout;
    
    	/**
    	 * 配置redis连接工厂
    	 *
    	 * @return
    	 */
    	public RedisConnectionFactory defaultRedisConnectionFactory() {
    		return createJedisConnectionFactory(dbIndex, host, port, password, timeout);
    	}
    
    	/**
    	 * 配置redisTemplate 注入方式使用@Resource(name="") 方式注入
    	 *
    	 * @return
    	 */
    	@Bean(name = "redisTemplateContainer")
    	public StringRedisTemplate defaultRedisTemplate() {
    		StringRedisTemplate template = new StringRedisTemplate();
    		template.setConnectionFactory(defaultRedisConnectionFactory());
    
    		template.afterPropertiesSet();
           
    		return template;
    	}
    	/**
    	 * 配置redis监听key消失
    	 * @return
    	 */
    	@Bean
    	public RedisMessageListenerContainer container() {
    		RedisMessageListenerContainer container = new RedisMessageListenerContainer();
    		container.setConnectionFactory(defaultRedisConnectionFactory());
    		container.addMessageListener(messageListener(), new ChannelTopic("czd_setting_1"));//配置redis订阅
    		return container;
    	}
    	/**
    	 * 配置redis订阅
    	 * @return
    	 */
    	@Bean
        MessageListenerAdapter messageListener() {
            return new MessageListenerAdapter( new MsgListener() );//MsgListener需要自己创建
        }
     
      
    }

2 新建MsgListener 用户接受订阅信息

import org.apache.log4j.Logger;
    import org.springframework.data.redis.connection.Message;
    import org.springframework.data.redis.connection.MessageListener;
    import org.springframework.stereotype.Component;
    
    import com.game.monopoly.service.dare.czd.robot.CzdRobotService;
    import com.game.msg.entity.SocketMessage;
    import com.game.util.JsonTool;
    
    @Component
    public class MsgListener implements MessageListener {
    	protected final static Logger logger = Logger.getLogger(MsgListener.class);
    	/**
    	 * 读取订阅消息
    	 */
        @Override
        public void onMessage(Message message, byte[] pattern) {
        	logger.info( "Message received: " + message.toString() );//打印信息
        }
    }

3 新建RedisSendMsg类用于发送信息

import javax.annotation.Resource;
    
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.stereotype.Component;
    
    import com.game.msg.entity.SocketMessage;
    import com.game.util.SpringManager;
    
    @Component("redisSendMsg")
    public class RedisSendMsg {
    
    	@Resource(name = "redisTemplateContainer")
    	private StringRedisTemplate redisTemplate;
    	public static RedisSendMsg util() {
    		return SpringManager.getBean(RedisSendMsg.class);
    	}
    	/**
    	 * 发送订阅消息
    	 * @param type
    	 */
    	public void sendMsg() {
    		redisTemplate.convertAndSend("czd_setting_1", "haha");
    	}
    	
    
    }

4 yml配置

redis:
      pool:
       max-active: -1
       max-wait: -1
       max-idle: 8
       min-idle: 0
      redis-container:
       database: 3
       host:ip
       port: 6379
       password: pwd
       timeout: 0
