简单测试步骤
1、导入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
我安装的是2.6.3的版本，该版本下默认的使用lettuce，而不是jedis，若想使用jedis，需要自己额外进行引用
2、配置文件
spring:
redis:
host: 127.0.0.1 # ip
port: 6379 # redis端口
password: # redis密码
3、测试

问题
?
１、nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘org.springframework.data.redis.core.RedisTemplate<java.lang.String, java.lang.Object>’ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
改成这个就可以使用了
