Several issues with "adding custom behaviour to all repositories" in spring data jpa

**balteo** · Jul 19th, 2012, 05:28 AM

Hello,

I use Spring data jpa and I am trying to add custom behaviour to all repositories as described here:
http://static.springsource.org/sprin...l-repositories

I encountered several issues:

-First, there is no such method as getDomainClass in the RepositoryMetadata class as described in the Spring documentation (see below):

Code:

protected Object getTargetRepository(RepositoryMetadata metadata) {
      return new MyRepositoryImpl<T, I>((Class<T>) metadata.getDomainClass(), entityManager);
}

I used the following method instead: getDomainType()

Is this right?

-Second my application throws exceptions when tomcat starts. Here is the full stack trace:

Code:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'globalRepositoryImpl' defined in file [E:\users\jumartin\dev_sts\.metadata\.plugins\org.eclipse.wst.server.core\
tmp0\wtpwebapps\SuiviTRC\WEB-INF\classes\trc\suivi\repository\GlobalRepositoryImpl.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could
 not instantiate bean class [trc.suivi.repository.GlobalRepositoryImpl]: No default constructor found; nested exception is java.lang.NoSuchMethodException: trc.suivi.repository.GlobalRepositoryImpl.<i
nit>()

Here is my custom global repository code:

Code:

public class GlobalRepositoryImpl<T, ID extends Serializable> extends SimpleJpaRepository<T, ID> implements GlobalRepository<T, ID> {

	private EntityManager em;

	public GlobalRepositoryImpl(Class<T> domainClass, EntityManager em) {
		super(domainClass, em);
		this.em = em;
	}

	public void sharedCustomMethod(ID id) {
		
	}

}

Here is my xml config:

Code:

<repositories base-package="trc.suivi.repository" factory-class="trc.suivi.repository.GlobalRepositoryFactoryBean">
		<repository id="pliRepository" />
		<repository id="globalRepository" />
	</repositories>

I was not able to find any other sample on the web. Can anyone please help?

Regards,

J.

That is the correct method.

This configuration does not match the one given in the reference documentation. Spring Data JPA will find your repositories automatically as long as the base-package is correct. Try changing your XML configuration to:

Code:

<repositories base-package="trc.suivi.repository" factory-class="trc.suivi.repository.GlobalRepositoryFactoryBean"/>

Hello Loke,

Thanks for taking the time to reply.

I altered the XML config as you advised to this:

Code:

	<repositories base-package="trc.suivi.repository" factory-class="trc.suivi.repository.GlobalRepositoryFactoryBean">
	</repositories>

Here is what I get:

Hi,

could you add the source code of the GlobalRepositoryFactoryBean class? Also, are you using Spring Data JPA 1.0.X or 1.1?

**balteo** · Jul 20th, 2012, 05:59 AM

Here is the code for GlobalRepositoryFactoryBean:

Code:

package trc.suivi.repository;

import java.io.Serializable;

import javax.persistence.EntityManager;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.support.JpaRepositoryFactory;
import org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean;
import org.springframework.data.repository.core.RepositoryMetadata;
import org.springframework.data.repository.core.support.RepositoryFactorySupport;

public class GlobalRepositoryFactoryBean<R extends JpaRepository<T, I>, T, I extends Serializable> extends JpaRepositoryFactoryBean<R, T, I> {

	protected RepositoryFactorySupport createRepositoryFactory(EntityManager entityManager) {
		return new GlobalRepositoryFactory(entityManager);
	}

	private static class GlobalRepositoryFactory<T, I extends Serializable> extends JpaRepositoryFactory {

		private EntityManager entityManager;

		public GlobalRepositoryFactory(EntityManager entityManager) {
			super(entityManager);
			this.entityManager = entityManager;
		}

		protected Object getTargetRepository(RepositoryMetadata metadata) {
			return new GlobalRepositoryImpl<T, I>((Class<T>) metadata.getDomainType(), entityManager);
		}

		protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
			return GlobalRepository.class;
		}
	}
}

I use: Spring data jpa: 1.1.0 & Spring data common: 1.3.0

Regards,

J.

**Loke** · Jul 20th, 2012, 06:12 AM

I found one problem from your repository factory bean. The method getRepositoryBaseClass returns the type of your base repository interface. It should return the type of your base repository implementation. Try changing this method to:

Code:

protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
	return GlobalRepositoryImpl.class;
}

Let me know if this did the trick.

**balteo** · Jul 20th, 2012, 06:33 AM

No luck...

I changed to GlobalRepositoryImpl.class but it still gives me the following exception:

I forgot to include the code for GlobalRepositoryImpl:

Here it is:

Code:

package trc.suivi.repository;

import java.io.Serializable;

import javax.persistence.EntityManager;

import org.springframework.data.jpa.repository.support.SimpleJpaRepository;

public class GlobalRepositoryImpl<T, ID extends Serializable> extends SimpleJpaRepository<T, ID> implements GlobalRepository<T, ID> {

	private EntityManager em;

	public GlobalRepositoryImpl(Class<T> domainClass, EntityManager em) {
		super(domainClass, em);
		this.em = em;
	}

	public void sharedCustomMethod(ID id) {
		
	}

}

**Loke** · Jul 20th, 2012, 06:49 AM

I am running out of ideas here. The only difference between your code and the code that is working for me is that I am using different constructor in my generic base repository. My constructor looks following:

Code:

public GenericBaseRepository(JpaEntityInformation<T, ID> entityMetadata, EntityManager entityManager) {
        super(entityMetadata, entityManager);
}

Here is the getTargetRepository() method of my repository factory bean.

Code:

@Override
protected Object getTargetRepository(RepositoryMetadata metadata) {
            return new GenericBaseRepository<T, I>((JpaEntityInformation<T,I>) getEntityInformation(metadata.getDomainType()), entityManager);
}

If does this does not help, you could add your application context configuration here. It might have some other clues about the problem.

**balteo** · Jul 20th, 2012, 06:59 AM

Here is my the changed code:

Code:

	public GlobalRepositoryImpl(JpaEntityInformation<T, ID> entityMetadata, EntityManager entityManager) {
		super(entityMetadata, entityManager);
	}

Code:

	@Override
		protected Object getTargetRepository(RepositoryMetadata metadata) {
		            return new GlobalRepositoryImpl<T, I>((JpaEntityInformation<T,I>) getEntityInformation(metadata.getDomainType()), entityManager);
		}

and the resulting exception:
