Spring Data - no transaction is in progress - spring

Question

I'm trying to configure a custom Spring Data Repository to replace some funcionality of spring.
Everything works fine in #Repository interfaces, but in the #Repository implementations, I got no transaction.
Error:
javax.persistence.TransactionRequiredException: no transaction is in progress
Here is my Configuration File:
#Configuration
#ComponentScan ({"com.app.core.authentication", "com.app.core.service","com.app.core.repository"})
#EnableTransactionManagement
#EnableJpaRepositories(basePackages = {"com.app.core.repository"})
public class AppCoreConfiguration implements TransactionManagementConfigurer {
#Bean
public DataSource dataSource() {
DataSource dataSource = null;
try {
Context ctx = new InitialContext();
dataSource = (DataSource) ctx.lookup("java:jboss/postgresDS");
} catch (NamingException e) {
e.printStackTrace();
}
return dataSource;
}
#Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(true);
vendorAdapter.setShowSql(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setPackagesToScan("com.app.core.entity");
factory.setDataSource(dataSource());
factory.afterPropertiesSet();
return factory.getObject();
}
#Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory());
txManager.setDataSource(dataSource());
return txManager;
}
#Bean
public HibernateExceptionTranslator hibernateExceptionTranslator(){
return new HibernateExceptionTranslator();
}
#Bean
public EntityManager entityManger () {
return entityManagerFactory().createEntityManager();
}
#Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return transactionManager();
}
}
And my repository class:
#Repository
public class ClientRepository extends JPABaseRepository<String, Client> implements IClientRepository {
#Autowired
public ClienteRepository (EntityManager em) {
super(Cliente.class, em);
}
#Override
#Transactional
public Cliente save(Client client) {
return saveAndFlush(client);
}
}
And the interface:
#NoRepositoryBean
public interface IClientRepository extends IJPABaseRepository<String, Client> {
...
}
Did someone know why this custom #Repository class didn't get the transaction manager?
This is strange, because all interfaces not implemented works fine...
I already tried to put #Transaction's annotation everywhere... including change from RESOURCE_LOCAL to JTA and so on...

Answer 1

When using custom JPA Repositories which extend Spring Data JPA you need a factory to create instances of those repositories. As mentioned in the Spring Data JPA documentation.
The problem with your current approach is the fact that you are creating a, non-spring-managed, instance of an EntityManager.
#Bean
public EntityManager entityManger () {
return entityManagerFactory().createEntityManager();
}
Normally Spring creates a transaction aware proxy for the EntityManager but in your case (due to the #Bean method) your custom implementation gets a plain EntityManager. Creating a factory (as mentioned above) will solve this.
