Repository is declared with @Repository but bean is not recognized

Question

This has been happening ever since i moved from Spring Data MongoDB to Spring Data Couchbase but even deleting the project as a whole and recreating did not solve the problem.

Every time I start my application throws:

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

Description:

Parameter 0 of constructor in com.minerva.borrowings.services.BorrowingServiceImpl required a bean of type 'com.minerva.borrowings.repositories.BorrowingRepo' that could not be found.


Action:

Consider defining a bean of type 'com.minerva.borrowings.repositories.BorrowingRepo' in your configuration.


Process finished with exit code 0

But my file structure is:

 └───com
    └───minerva
        └───borrowings
            │   BorrowingsApplication.java
            │   
            ├───config
            │       LoggingConfig.java
            │       NotificationConfig.java
            │       
            ├───controllers

                    BorrowingService.java
                    BorrowingServiceImpl.java

And the repository file is as such:

package com.minerva.borrowings.repositories;

import com.minerva.borrowings.entities.Borrowing;
import org.springframework.data.couchbase.repository.CouchbaseRepository;
import org.springframework.stereotype.Repository;

@Repository
   public interface BorrowingRepo extends CouchbaseRepository<Borrowing, String> {
}

And my BorrowingApplication.java uses @SpringBootApplication and does not allow to use @ComponentScan or @EnableJpaRepository

My pom.xml file is as such:

I've tried using JpaRepository and CrudRepository but the problem remains

Answer 1

Try out the @EnableCouchbaseRepositories annotation, maybe even by specifying the basePackages . Add a configuration bean like this:

@Configuration
@EnableCouchbaseRepositories(basePackages = "com.minerva.borrowings.repositories")
class CouchbaseDbConfig {
}
