java - 为什么Spring Boot时找不到bean？

Question

我以更方便的方式重新配置了 DAO(通过使用 JpaRepository)，而不是手动执行所有样板代码。但现在每次我启动 Spring 应用程序时都会出现以下错误:

APPLICATION FAILED TO START  
Description:  
Field userRepository in DAO.UserDAOService required a bean of type 'DAO.UserRepository' that could not be found.
    
The injection point has the following annotations:
        - @org.springframework.beans.factory.annotation.Autowired(required=true)
    
Action:
Consider defining a bean of type 'DAO.UserRepository' in your configuration.
Process finished with exit code 1
    

Answer 1

解决方案:只需在 Spring 应用程序所在的同一包中创建子包即可。
