@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

<bean id="entityManagerFactory" 
 class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">   
    <property name="dataSource" ref="dataSource" />   
    <property name="packagesToScan">   
        <list>   
            <value>net.com.htts.transaction.data</value>   
            <value>net.com.htts.transaction.data.repository</value>   
        </list>   
    </property>

</beans>   

Answer 1

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 .

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

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
