@Autowired cant find repository bean identified with @Repository

Question

If you cant find the bug at least say yes or no that i have carried out all the correct steps, that way at least I a can think that there is another error in my context xml file

The error is as follows

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [net.com.htts.transaction.service.mapping.FundService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

I have a Junit test which cant load the a repository bean.

1) I created a interface FundRepository view plaincopy to clipboardprint? Note: Text content in the code blocks is automatically word-wrapped package net.com.htts.transaction.data.repository;

import org.springframework.stereotype.Repository;   
import net.com.htts.transaction.data.entity.Fund;   

@Repository  
public interface FundRepository {    
public void createFund(Fund fund);   
}  

package net.com.htts.transaction.data.repository;

import org.springframework.stereotype.Repository;
import net.com.htts.transaction.data.entity.Fund;

@Repository
public interface FundRepository { 
public void createFund(Fund fund);
} 

The interface has the @Repository

2) I created the FundRepositoryImpl which implements my interface

view plaincopy to clipboardprint? Note: Text content in the code blocks is automatically word-wrapped package net.com.htts.transaction.data.repository;

import java.util.List;   

import net.com.htts.transaction.data.entity.Fund;   

import javax.persistence.EntityManager;   
import javax.persistence.PersistenceContext;   
import javax.persistence.PersistenceContextType;   

public class FundRepositoryImpl implements FundRepository{   

@PersistenceContext(type = PersistenceContextType.EXTENDED)   
private EntityManager entityManager;   

public void createFund(Fund fund) {   
    entityManager.persist(fund);   
}   
     }  
    package net.com.htts.transaction.data.repository;
import java.util.List;

import net.com.htts.transaction.data.entity.Fund;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.PersistenceContextType;

public class FundRepositoryImpl implements FundRepository{

@PersistenceContext(type = PersistenceContextType.EXTENDED)
private EntityManager entityManager;

public void createFund(Fund fund) {
    entityManager.persist(fund);
}
}

Created the spring data context

in this context i added the following

view plaincopy to clipboardprint? Note: Text content in the code blocks is automatically word-wrapped

           <!-- Scan the repositories -->   
<jpa:repositories base-package="net.com.htts.transaction.data.repository" />  
           <!-- Scan the data layer -->
<context:component-scan base-package="net.com.htts.transaction.data" />

           <!-- Scan the repositories -->
<jpa:repositories base-package="net.com.htts.transaction.data.repository" />

According to everything i have read this should be enough to allow me to @Autowired in FundRepository.

The Junit is as follows

@RunWith(SpringJUnit4ClassRunner.class)   
@ContextConfiguration("classpath:/spring/fund-test-data.xml")   
public class FundRepositoryTest {   

@Autowired    
 private FundRepository repository;   



@Test  
public void createFund(){   
}   

}

The context is as follows

 class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">   
    <property name="dataSource" ref="dataSource" />   
    <property name="packagesToScan">

</beans>   

Answer 1

1) From your log snippet No matching bean of type [net.com.htts.transaction.service.mapping.FundService] indicates that the problem is with a definition of FundService somewhere in your project which I did not see anywhere in the presented sources.

Double check that you are indeed having problems with the repo and attach the appropriate log, or take a look at that service

2) If you want to simplify your code and avoid rewriting again the data access layer, you can take advantage of spring data repositories

Answer 2

annotation do not inherited, you should use annotation in class that implemented interface. if you have to implementation you must use @Qualifire

Answer 3

Afaik the @Repository annotation must be present on the concrete implementation, not the interface. Spring will not find and instantiate your FundRepositoryImpl, as it is not marked with any of the component annotations. In general, annotations in java are not inherited. Some frameworks allow annotation inheritance through other means. See also this question.
