一、添加pom

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

二、配置RedisConfig

package com.example.redismqdemo;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
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.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import java.net.UnknownHostException;

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory)
            throws UnknownHostException {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(factory);
        //  Json序列化配置
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        // 指定要序列化的域，field,get和set,以及修饰符范围，ANY是都有,包括private和public
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        // 指定序列化输入的类型，类必须是非final修饰的，final修饰的类，比如String,Integer等会抛出异常
        //om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);  //@Deprecated 已过时
        jackson2JsonRedisSerializer.setObjectMapper(om);

        //配置具体的序列化方式
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        //key采用String的序列化方式
        template.setKeySerializer(stringRedisSerializer);

        //hash的key也采用String的序列化方式
        template.setHashKeySerializer(stringRedisSerializer);

        //value序列化采用jackson
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();

        return template;
    }
}

三、配置消费端

package com.example.redismqdemo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

@Component
public class Receiver {
    @Autowired
    private RedisTemplate<String,Object> redisTemplate;

    public void onMsg(String msg){
        System.out.println("hhhhhhhhhhh");
        System.out.println("get msg:::"+msg.toString());
    }

}

四、配置RedisMessageListenerContainer

package com.example.redismqdemo;

import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.listener.PatternTopic;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.data.redis.listener.adapter.MessageListenerAdapter;

@Configuration
@AutoConfigureAfter(Receiver.class)
public class SubscribeConfig {

    @Bean
    public MessageListenerAdapter myMsgAdpater(Receiver receiver) {
        return new MessageListenerAdapter(receiver, "onMsg");
    }

    @Bean
    public RedisMessageListenerContainer myRedisMsgListenerContainer(RedisConnectionFactory redisConnectionFactory,MessageListenerAdapter myMsgAdpater){
        RedisMessageListenerContainer redisMessageListenerContainer = new RedisMessageListenerContainer();
        redisMessageListenerContainer.setConnectionFactory(redisConnectionFactory);
        redisMessageListenerContainer.addMessageListener(myMsgAdpater,new PatternTopic("topic"));
        return redisMessageListenerContainer;
    }
}

PS：可以订阅多个topic，创建不同的MessageListenerAdapter即可，通过Adapter绑定消费方法。

五、测试（生产端）

@SpringBootTest
class RedisMqDemoApplicationTests {

    @Autowired
    RedisTemplate<String,Object> redisTemplate;

    @Test
    void contextLoads() {
        String channel = "topic";
        redisTemplate.convertAndSend(channel, "hello world");
    }

}
