Can't retrieve the spring application context in a multimodule springboot project / EntityManagerFactory can not be found

Question

I have a multimodule springboot project. Here is the architecture:

The class annotated with @SpringBootApplication is in the top module (webservice). When I run integration test from this top module using @SpringBootTestin my test classes, it works fine.

But now I'd like to run integration test from the business module. @SpringBootTest only doesn't work anymore because no config class can be found in the business module. So I created a config class in the business module:

package com.berthoud.p7.webserviceapp.business.config;

import org.springframework.boot.SpringBootConfiguration;
import org.springframework.context.annotation.ComponentScan;

@SpringBootConfiguration
@ComponentScan(basePackages = "com.berthoud.p7")
public class TestContextConfiguration {
}

And in my test classes, I pointed to this config class, like this :

@RunWith(SpringRunner.class)
@SpringBootTest(classes = TestContextConfiguration.class)
public class BookResearchIT {
//my tests...
}

Doing so, I was hopping that Spring would add to the context all the beans declared in the package com.berthoud.p7 and its subfolders. Indeed, when I autowire spring beans in my test classes it now looks fine (IntelliJ doesnt tell anymore that the @autowiredbeans cannot be autowired):

But nevertheless, when I run my tests, Spring fails to load the application context :

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

Description:

Field bookReferenceDAO in com.berthoud.p7.webserviceapp.business.BookResearchManager required a bean of type 'com.berthoud.p7.webserviceapp.consumer.contract.BookReferenceDAO' 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.berthoud.p7.webserviceapp.consumer.contract.BookReferenceDAO' in your configuration.

I don't understand this. Here is how I declared the beans concerned :

package com.berthoud.p7.webserviceapp.business;

@Service
public class BookResearchManager {

    @Autowired
    BookReferenceDAO bookReferenceDAO;

    @Autowired
    LibrairyDAO librairyDAO;

    @Autowired
    BookDAO bookDAO;

package com.berthoud.p7.webserviceapp.consumer.contract;

public interface BookReferenceDAO {
// method signatures
}

package com.berthoud.p7.webserviceapp.consumer.repositories.SpringDataJPA;

public interface BookReferenceRepository extends CrudRepository<BookReference, Integer>, BookReferenceDAO {

What did I do wrong?

EDIT: after changing my config class like this :

package com.berthoud.p7.webserviceapp.business.config;

import org.springframework.boot.SpringBootConfiguration;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;


@SpringBootConfiguration
@ComponentScan(basePackages = "com.berthoud.p7.webserviceapp")
@EnableJpaRepositories(basePackages = "com.berthoud.p7.webserviceapp.consumer")
@EntityScan(basePackages = "com.berthoud.p7.webserviceapp")
public class TestContextConfiguration {
}

I now have a different error :

Field bookReferenceDAO in com.berthoud.p7.webserviceapp.business.BookResearchManager required a bean named 'entityManagerFactory' that could not be found.

Does the application run at all? I would say you need to annotate your BookResearchManager with @Component — Cwrwhaf, Sep 06 '19 at 10:57
the application runs perfectly, and as I wrote I can run the tests from the top module. — Julien Berthoud, Sep 06 '19 at 10:58
Edit : BookResearchManager was always annotated with @service in my code — Julien Berthoud, Sep 06 '19 at 11:05
