redis集群springboot集成方式

pom

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

		<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>2.9.0</version>
		</dependency>

我的项目中，spring boot是 用的2.1.8版本.

spring-boot-starter-redis在springboot 1.4.7版本后,

改为了spring-boot-starter-data-redis,

所以如果想集成redis,

应该引用spring-boot-starter-data-redis.

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-redis</artifactId>
            <version>1.4.7.RELEASE</version>
        </dependency>
