文章描述了一位开发者在使用SpringBoot应用时遇到的错误，Redis服务未开启导致Bean初始化失败，表现为BeanCreationException，错误信息指出连接本地主机6379端口失败。解决方法是确保Redis服务已启动并检查网络连接。

解决方案

Redis服务没开，天天错，天天忘

可以看到报错信息中，ERROR的下一行，BeanCreationException为Bean注入错误，末尾写了Unable to connect to localhost:6379，6379就是redis服务常用的端口

如果你的电脑已经配置了redis的环境，在cmd中使用如下指令开启服务

redis-server

详细报错信息

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
