Including Spring context from an external jar does not find services

Tags:

spring-boot

I am currently using Spring Boot and annotation-based configuration to manage my spring applications. The project is composed of a registration and an external library of services.

Service is composed of classes annotated with @Service and have a @Reposity injected into them.

Registration injects the @Service.

Project Structure (4 maven projects):

xelamitchell (Parent POM)
  +- domain
  +- service (Spring JPA)

registration (separate project with Spring Boot)

Registration has a maven dependecy to service.

PersonService:

package org.xelamitchell.service.person;

import org.xelamitchell.domain.person.Person;
import java.util.List;

/**
 * Manages {@link Person}s.
 * 
 * @author amitchell
 */
public interface PersonService {

    List<Person> list();

    Person get(Long id);

    Boolean exists(Long id);

    Person save(Person person);

    Boolean delete(Long id);

}

package org.xelamitchell.service.person;

import org.xelamitchell.domain.person.Person;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Service;

/**
 *
 * @author amitchell
 */
@Primary
@Service
public class DefaultPersonService implements PersonService {

    private PersonRepository repository;

    protected DefaultPersonService() {}

    @Autowired
    public DefaultPersonService(PersonRepository repository) {
        this.repository = repository;
    }

    @Override
    public List<Person> list() {
        return repository.findAll();
    }

    @Override
    public Person get(Long id) {
        return repository.findOne(id);
    }

    @Override
    public Boolean exists(Long id) {
        return repository.exists(id);
    }

    @Override
    public Person save(Person person) {
        return repository.save(person);
    }

    @Override
    public Boolean delete(Long id) {

        if(id != null) {
            repository.delete(id);
        }

        return repository.exists(id);
    }

}

PersonRepository:

package org.xelamitchell.service.person;

import org.xelamitchell.domain.person.Person;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

/**
 *
 * @author amitchell
 */
@Repository
public interface PersonRepository extends JpaRepository<Person, Long> {

}

Service Library configuration:

@Configuration
public class ServiceContext {
}

Application configuration:

@Configuration
@ComponentScan(basePackages = {"org.xelamitchell"})
@EnableAutoConfiguration
//@Import({WebContext.class, ServiceContext.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Spring boot is defined in the POM for Application.

The exception I keep getting is that the @Repository classes were not able to be injected into their respective @Service:

Edited after the discussion...

Add the "@EnableJpaRepositories" and "@EntityScan" on top of your Application class.

@EnableJpaRepositories("org.xelamitchell")
@EntityScan("org.xelamitchell")

HTH...
