我正在使用 Spring Data Redis 示例。在此示例中，只是尝试连接到 redis 数据库。运行主要方法，出现以下错误。

Spring Boot 使用的版本是 v 2.0.3.RELEASE & Redis version 是 2.4.5。

代码引用取自: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 .任何人都可以建议这里有什么问题吗？

最佳答案

您的示例引用了使用 Jedis 的 boot 1.5.X，默认情况下 lettuce 在 Boot 2.0 中使用> 如果你想使用 Jedis 你需要手动添加依赖。此外，您可以看到 Jedis 不在您的类路径中，而 lettuce 在。

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

您可能需要指定依赖版本。或者，您可以通过 lettuce 配置您正在尝试的内容。

关于spring - 由: java. lang.BootstrapMethodError : java. lang.NoClassDefFoundError: redis/clients/jedis/Tuple引起 - Redis Spring Boot，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51332154/
