1、添加依赖

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

2、配置文件

# redis
spring.redis.host=localhost
spring.redis.database=0
spring.redis.port=6379
spring.redis.password=

3、配置类

package com.shenmazong.send.config;

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.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @author 军哥
 * @version 1.0
 * @description: 配置自定义redisTemplate
 * @date 2022/2/9 11:23
 */

@Configuration
@EnableCaching
public class RedisConfig {
    /**
     * 配置自定义redisTemplate
     * @return
     */
    @Bean
    RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {

        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        // 设置值（value）的序列化采用Jackson2JsonRedisSerializer。
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // 设置键（key）的序列化采用StringRedisSerializer。
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());

        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

4、测试类

package com.shenmazong.send;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;

import java.util.ArrayList;
import java.util.concurrent.TimeUnit;

@SpringBootTest
class ServerShopSendApplicationTests {

    @Autowired
    RedisTemplate redisTemplate;

    @Test
    void testRedis() {
        ArrayList<String> names = new ArrayList<>();
        names.add("zhangsan");
        names.add("李四");
        redisTemplate.opsForValue().set("hello", names, 60, TimeUnit.MINUTES);

        //
        Object hello = redisTemplate.opsForValue().get("hello");
        System.out.println(hello);
    }
}
