我使用的是Spring Data Redis示例。在本例中，只需尝试连接到redisDB。运行主方法，我得到以下错误。
Spring Boot使用的版本是v2.0.3。RELEASE&Redis版本是2.4.5。
代码参考取自：http://javasampleapproach.com/spring-framework/spring-data/spring-data-redis-example-spring-boot-redis-example和https://docs.spring.io/spring-session/docs/current/reference/html5/guides/boot-redis.html.有人能告诉我这里出了什么问题吗？

您的示例引用了使用Jedis的引导1.5.X，默认情况下，在引导2.0中使用lettuce。如果要使用Jedis，则需要手动添加依赖项。此外，您可以看到Jedis不在类路径中，而lettuce在.中
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
您可能需要指定依赖项版本。或者，您可以通过lettuce配置您正在尝试的内容。
