spring-data-rest, обычный настраиваемый метод для всех репозиториев

Я пытаюсь создать базовую функциональность для всех репозиториев хранения данных с пружинными данными, но настойчивую проблему.spring-data-rest, обычный настраиваемый метод для всех репозиториев

Версия весны - 4.2.4, у меня есть UserRepository, привязанный к относительной пользовательской сущности, а также UserController, управляющий логикой, связанной с несколькими репо.

Я хочу добавить собственный метод sharedCustomMethod ко всем моим репозиториям, включая UserRepository.

Я BaseRepositoryRelated классы и интерфейсы:

@NoRepositoryBean 
public interface BaseRepository <T, E extends Serializable> 
extends PagingAndSortingRepository<T, E>, BaseRepositoryCustom<T, Serializable> { 

    @Override 
    @Query("select e from #{#entityName} e where e.enabled=1 and e.id=?1") 
    T findOne(E primaryKey); 

    @Override 
    @Query("select e from #{#entityName} e where e.enabled=1") 
    Iterable<T> findAll(); 

    @Override 
    @Query("select count(*) from #{#entityName} e where e.enabled=1") 
    long count(); 

    @Override 
    @Query("update #{#entityName} e set e.enabled=0 where e.id=?1") 
    @Modifying 
    void delete(E primaryKey); 
}

пользовательского интерфейса:

package com.eolcum.repository.base; 

import java.io.Serializable; 

import org.springframework.data.repository.NoRepositoryBean; 

@NoRepositoryBean 
public interface BaseRepositoryCustom <T, E extends Serializable> { 

    void sharedCustomMethod(E id); 
}

Пользовательские Impl:

package com.eolcum.repository.base; 

import java.io.Serializable; 

import javax.persistence.EntityManager; 

import org.springframework.data.jpa.repository.support.SimpleJpaRepository; 
import org.springframework.transaction.annotation.Transactional; 

public class BaseRepositoryImpl<T, ID extends Serializable> 
    extends SimpleJpaRepository<T, Serializable> 
    implements BaseRepository<T, Serializable> { 

    private final EntityManager entityManager; 

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

    @Override 
    @Transactional 
    public void sharedCustomMethod(Serializable id) { 
     System.out.println("done!"); 

    } 

}

BaseRepo Factory Bean:

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

     private final EntityManager em; 

     public BaseRepositoryFactory(EntityManager em) { 
      super(em); 
      this.em = em; 
     } 

     @Override

       EntityManager entityManager) {

     } 

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

PersistenceContext: package com.eolcum.repository.base;

import org.springframework.context.annotation.Configuration; 
import org.springframework.data.jpa.repository.config.EnableJpaRepositories; 
import org.springframework.transaction.annotation.EnableTransactionManagement; 

import com.eolcum.controller.UserController; 

@Configuration 
@EnableJpaRepositories(basePackages = {"com.eolcum.repository.base"}, 
     repositoryFactoryBeanClass = BaseRepositoryFactoryBean.class) 
@EnableTransactionManagement 
public class PersistenceContext { 

}

Когда я пытаюсь запустить приложение с пружинным ботинке я получаю следующее сообщение об ошибке:

Благодарим за помощь заранее.

  1. Создать базовый интерфейс с @NoRepository аннотацию, как показано ниже:

    @NoRepositoryBean 
public interface BaseRepository<T extends BaseModel, ID extends Serializable> 
     extends PagingAndSortingRepository<T, ID> { 

    T checkAsDeleted(T t); 

}

  2. Создать базовый класс и расширить базовый интерфейс

    @Transactional(readOnly = false) 
public class BaseRepositoryImpl<T extends BaseModel, ID extends Serializable> 
    extends SimpleJpaRepository<T, ID> 
    implements BaseRepository<T, ID> { 

    public BaseRepositoryImpl(JpaEntityInformation<T, ?> entityInformation, EntityManager entityManager) { 
     super(entityInformation, entityManager); 
    } 

    public BaseRepositoryImpl(Class<T> domainClass, EntityManager em) { 
     super(domainClass, em); 
    } 

    @Override 
    public T checkAsDeleted(T t) { 
     t.setIsDeleted(true); 
     return this.save(t); 
    } 

    @Override 
    public <S extends T> S save(S entity) { 
     Date now = new Date(); 
     if (entity.getId() == null) { 
      entity.setCreationDate(now); 
     } 
     entity.setModifiedDate(now); 
     return super.save(entity); 
    } 
}

  3. Расширьте хранилище интерфейс с базовым интерфейсом

    @Repository 
public interface QuestionRepository extends BaseRepository<Question, Long> { 

    List<Question> findByisDeleted(boolean isDeleted); 

    List<Question> findAll(); 

}

  4. Пусть знают это базовый класс для приложения

    @SpringBootApplication 
@EnableJpaRepositories(repositoryBaseClass = BaseRepositoryImpl.class) 
@EnableSpringDataWebSupport 
public class Application { 

    public static void main(String[] args) { 
     SpringApplication.run(Application.class, args); 
    } 
}

Теперь у вас есть checkAsDeleted() метод везде!

Все коды работают в реальном проекте
