Spring Boot 2.5.4 应用程序中 JedisClient 初始化时出现 ClassNotFoundException

Mar*_*tin 11 java redis jedis spring-data-redis spring-boot

我有一个 Spring Boot 2.5.4 应用程序，我想在其中添加 Redis 并通过 Spring Data Redis 访问它。我当前的配置如下所示：

到目前为止，我已经尝试通过减少和增加来操纵redis.clients和版本，但总是会出现初始化问题。spring-boot-starter-data-redis我发现的每个教程都不包含新的 Spring Boot 应用程序版本的配置。我将不胜感激有关如何操作 pom.xml 版本redis.clients并使spring-boot-starter-data-redis应用程序重新启动的建议。

Joã*_*ias 25

spring-boot-starter-data-redis已经jedis作为依赖项包含在内，因此您不应将其添加到 pom.xml 中，其版本可能与您的spring-boot-starter-data-redis.

对于spring-boot-starter-data-redis版本 2.5.0，它包括jedis版本 3.6.3，但您可以使用版本 3.1.0 覆盖它，这可能与版本 2.5.0 不兼容spring-boot-starter-data-redis。

始终检查 Spring Boot Starters 中已包含的依赖项，因为不兼容正是他们试图避免的。

话虽如此，我并不完全确定这会解决问题，但这是一个很好的起点。

该spring-boot-starter-data-redis依赖pom.xml包括以下依赖：

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-redis</artifactId>
  <version>2.5.1</version>

这意味着您应该只将依赖项添加到您的版本中pom.xml，但不设置任何版本，以便spring-data-redis使用中设置的版本，如下所示：
