jparepository not autowired in service

Question

I am trying to autowire a repository in a service but I keep getting the following error

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'articleService': Unsatisfied dependency expressed through field 'articleRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.mvc.stock.repository.ArticleRepository' available: expected at least 1 bean which qualifies as autowire candidate.

Here is my configuration

    <property name="entityManagerFactory" ref="entityManagerFactory"></property>
</bean>

<context:component-scan base-package="com.mvc.stock" />

here is my code

@Service
@Transactional
public class ArticleService {

    @Autowired
    private ArticleRepository articleRepository;
}

and the repository

 @Repository
 public interface ArticleRepository extends JpaRepository<ArticleRepository, Long>{

}

Answer 1

You didn’t instruct Spring to generate the repositories. This is done via:

<jpa:repositories base-package="foo.bar" />

You probably also want to enable annotation driven transaction management:

<tx:annotation-driven />

See How to configure Spring Data JPA using XML

Answer 2

Error says:

org.springframework.beans.factory.UnsatisfiedDependencyException: 
Error creating bean with name 'articleService': Unsatisfied dependency expressed through field 'articleRepository'; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'com.mvc.stock.repository.ArticleRepository' available: 
expected at least 1 bean which qualifies as autowire candidate. 
Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

UnsatisfiedDependencyException due to nested Exception NoSuchBeanDefinitionException in ArticleRepository.

Most of the time it comes due to absence of @Repository. But in your case check ArticleRepository interface you have used JpaRepository<ArticleRepository, Long> instead of JpaRepository< Article, Long>

ArticleRepository:

@Repository
public interface ArticleRepository extends JpaRepository< Article, Integer> {

}

ArticleService

    @Service
    class articleService{

    @Autowired
    ArticleRepository articleRepository;
    //other fields 

    }
