リポジトリファクトリBeanによって作成されたリポジトリを自動配線しようとしています。特定のリポジトリのsave（）メソッドをカスタムコードでオーバーライドする必要があります。Spring Dataの紹介で、ファクトリBeanの例に従いました。
しかし、私が何をするにしても、私は得ていNoSuchBeanDefinitionExceptionます。
一方、「インターフェースのみのリポジトリ」は問題なく作成され、注入されます。
どこかでばかげた間違いをしている可能性が非常に高いです。これはSpringData101であると想定されているためです。
誰かが私にそれを機能させるために他に何をしようとしているのかについての手がかりを教えてもらえますか？

リポジトリファクトリ
エンティティのタイプがBarの場合、別のリポジトリを返します。それ以外の場合は、デフォルトの動作が適用されます。
public class RepositoryFactoryBean<R extends JpaRepository<T, I>, T, I extends Serializable> extends JpaRepositoryFactoryBean<R, T, I> {
protected RepositoryFactorySupport createRepositoryFactory(EntityManager entityManager) {
return new MyRepositoryFactory(entityManager);
}
private static class MyRepositoryFactory<T, I extends Serializable> extends JpaRepositoryFactory {
private EntityManager entityManager;
public MyRepositoryFactory(final EntityManager entityManager) {
super(entityManager);
this.entityManager = entityManager;
}
protected Object getTargetRepository(final RepositoryMetadata metadata) {
if (metadata.getDomainType().equals(Bar.class)) {
return new BarDaoImpl((Class<Bar>) metadata.getDomainType(), entityManager);
}
return super.getTargetRepository(metadata);
}
protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
if (metadata.getDomainType().equals(Bar.class)) {
return BarDao.class;
}
return super.getRepositoryBaseClass(metadata);
}
}
}
リポジトリクラスとインターフェイス
package com.bar.persistence.dao;
@NoRepositoryBean
public interface BarDao extends JpaRepository<Bar, Long> {
// no methods - because I want to override save()
}
package com.bar.persistence.dao;
public class BarDaoImpl extends SimpleJpaRepository<Bar, Long> implements BarDao {
public BarDaoImpl(final Class<Bar> domainClass, final EntityManager em) {
super(domainClass, em);
}
@Override
public <S extends Bar> S save(final S entity) {
// some code to perform before actually saving the entity
entity.setName("intercepted save !");
// do the save
return super.save(entity);
}
}
リポジトリを挿入するテスト
注入するタイプBarDaoのBeanが見つからないため、テストは失敗します。
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/persistence-beans.xml")
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
@TransactionConfiguration
public class SpringDataLearningTest {
@Autowired
private BarDao barDao;
@Transactional
@Test
public void testModifiedSave() throws Exception {
final Bar original = createRandomBar();
final Bar saved = barDao.save(original);
assertNotNull("No id was assigned to the saved entity", saved.getId());
assertEquals("intercepted save !", saved.getName());
}
private static Bar createRandomBar() {...}
}
