Nested transaction in Spring app with JPA (postgres)

Question

Is it possible to have PROPAGATION_NESTED in @Transactional() with JPA using postgres? I am getting:

org.springframework.transaction.NestedTransactionNotSupportedException:
JpaDialect does not support savepoints - check your JPA provider's capabilities

I tried:

@Bean
public PlatformTransactionManager transactionManager() {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory()
                .getObject());
    transactionManager.setNestedTransactionAllowed(true);
    return transactionManager;
}

But with no success.

Answer 1

I am assuming that you are using Hibernate. NESTED transactions is not possible with Hibernate.

In the following code excerpt, spring sets savePointManager. But there is no class implementing SavepointManager in Hibernate.
