1、redis依赖

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

2、测试类

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTest {
    @Autowired
    private RedisTemplate<String,String> redisTemplate;

    @Test
    public void set(){
        redisTemplate.opsForValue().set("myKey","myValue");
        System.out.println(redisTemplate.opsForValue().get("myKey"));
    }
}
