Getting " No matching bean of type [..] found for dependency" using spring-data-jpa

[tomcatlee]

I am using spring-mvc 3.1.0.RELEASE,recently I want to add spring-data-jpa 1.0.3.RELEASE in my web project, but failed. I got error:
No matching bean of type [..] found for dependency, expected at least 1 bean which qualifies as autowire candidate for this dependency

I have a post in stackoverflow.

I am wondering how to get rid of this error. I am also curious about how spring creating a instance of my repository interface. And is there any special configuration?

Hello

Next time use code tags, and post here the complete error stack trace. The error is obvious, a missing bean dependency, I hope you have a correct configuration to scan the packages and get the annotated beans

Read the Spring Reference documentation for more details, there are many examples too

Thanks for the reply. I put my code here:

My configuration:

	<!-- Activate Spring Data JPA repository support -->
  	<jpa:repositories base-package="com.mypackage.repository" />
</beans>

My repository:

package com.mypackage.repository;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;
import com.mypackage.pbo.PSubject;
public interface SubjectRepository extends JpaRepository<PSubject, String>{
	public Page<PSubject> findByType(String title, Pageable pageable);
	public Page<PSubject> findByType(String title);
	public Page<PSubject> findByMacaddress(String macaddress, Pageable pageable);
	public Page<PSubject> findByMacaddress(String macaddress);
	public Page<PSubject> findByUri(String uri);
}

My service:

....
@Transactional
@Service("subjectService")
public class SubjectServiceImpl implements SubjectService
{
	private final SubjectRepository subjectRepository;
	@Autowired
	public SubjectServiceImpl(SubjectRepository subjectRepository){
		this.subjectRepository = subjectRepository;
	}

It seems everything just like the example of spring site except I integrate it into my spring mvc project. But when starting my project, I got error:

org.springframework.beans.factory.NoSuchBeanDefini tionException: No matching bean of type [com.mypa.repository.SubjectRepository] found for dependency

Hello

org.springframework.beans.factory.NoSuchBeanDefini tionException: 
No matching bean of type [com.mypa.repository.SubjectRepository] found for dependency

OK

I am not an expert with Spring Data but according with

        private final SubjectRepository subjectRepository;

	@Autowired
	public SubjectServiceImpl(SubjectRepository subjectRepository){
		this.subjectRepository = subjectRepository;
	}

1) why you are using final?
2) Where you have defined a class annotated with @Repository to be scanned and be used within the application context and It class implements the interface SubjectRepository?

Hi, I removed "final",nothing changed. For your doubt 2： Where you have defined a class annotated with @Repository to be scanned and be used within the application context

There are two kinds of repositories in Spring data jpa, what you said is a classic one. And in the tutorial of spring data jpa, it said you can just extends a interface of spring data jpa, no need to implement this interface, and no annotation needed.
