Java com.example.RedisApplication中方法存储库的参数0需要找不到类型的bean

我在Spring Boot+Spring Data Redis上做POC，参考并简单地遵循教程，使用Spring Boot版本

2.1.0。RELEASE

而不是

2.0.0。RELEASE

我只是将Redis缓存更新到DB中，并得到以下错误

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of method repositories in com.example.RedisApplication required a bean of type 'com.example.RedisApplication$LineItemRepository' that could not be found.


Action:

Consider defining a bean of type 'com.example.RedisApplication$LineItemRepository' in your configuration.

我能够解决这个问题。不知何故，订单和行项目的存储库引用不可用。所以我只是将POJO和Repository类从main方法中移出
