原因是我们的 Redis 使用了线程池的缘故，从 https://start.spring.io/ 创建的项目少了线程池相关的包
修复方法
如果你是用的是 maven 作为依赖管理工具，那么请添加
<dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-pool2</artifactId> <version>2.6.2</version> </dependency>
如果使用的是 Gradle ，比如我，哈哈，那么添加下面的东西到 `build.gradle
implementation 'org.apache.commons:commons-pool2:2.6.2'
目前尚无回复
