spring-4

With Spring 4 and Hibernate 4, I was able to use Reflection to get the Hibernate Configuration object from the current environment, using this code: @Autowired LocalContainerEntityManagerFactoryBean lcemfb; EntityManagerFactoryImpl emf = (EntityManagerFactoryImpl) lcemfb.getNativeEntityManagerFactory(); SessionFactoryImpl sf = emf.getSessionFactory(); SessionFactoryServiceRegistryImpl serviceRegistry = (SessionFactoryServiceRegistryImpl) sf.getServiceRegistry(); Configuration cfg = null; try { Field field = SessionFactoryServiceRegistryImpl.class.getDeclaredField("configuration"); field
