Description:

The bean 'dataSource', defined in BeanDefinition defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

同学，问题解决了吗？建议你下载老师代码好好对比一下，应该是你配置哪里出错了

看着像你引入的数据库相关依赖版本冲突了，你保持和视频里一样的版本，如果还不行，push一下代码，回复我代码地址，我帮你看看。
