[FIXED] Issue in defining a bean of type

Issue

I tried to Create Interface by extending the CRUD Repository with annotation @Repository. Also I tried to use the interface function in Service class using Auto wired annotation. But I am facing the issue given below

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

Description:

Field bookRepository in com.example.service.BookService required a bean of type 'com.example.repo.BookRepository' 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 'com.example.repo.BookRepository' in your configuration.

Project Structure are given below:

Solution

The problem is with your project structure. Try replacing all other packages under:

com.example.learn 

package

Folowing above you won't need @ComponentScan and @Repository as @SpringBootApplication will take care of it.
