* JPA support is fully tested against Oracle TopLink Essentials v2 b16 as well as Hibernate EntityManager 3.2.0 CR4 * removed ORM support for Apache OJB from the Spring core distribution. OJB support EXTENDED anymore * fixed JpaDaoSupport's "setEntityManager" method to accept an EntityManager instead of an EntityManagerFactory * removed "getEntityManager()"/"getEntityManagerFactory()" removed "allowCreate" flag from JpaTemplate, always allowing creation (analogous to shared EntityManager) * added "exceptionConversionEnabled" flag to HibernateInterceptor, TopLinkInterceptor

Background Bootstrapping ..... 172 5.4.2. Implementing DAOs Based on JPA: EntityManagerFactory and EntityManager ..... 173 5.4.3. Spring-driven JPA transactions ..... 176 5.4.4. Understanding JpaDialect JDBC-based repository needs access to a JDBC DataSource, and a JPA-based repository needs access to an EntityManager. The easiest way to accomplish this is to have this resource dependency injected by using one @PersistenceContext private EntityManager entityManager; // ... } Kotlin @Repository class JpaMovieFinder : MovieFinder { @PersistenceContext private lateinit var entityManager: EntityManager } If you use

args) { EntityManagerFactory emf = Persistence .createEntityManagerFactory("shop"); EntityManager em = null; try { em = emf.createEntityManager(); em.getTransaction().begin(); SpringJpaProductRepository implements ProductRepository { @PersistenceContext private EntityManager em; AOP proxy around EntityManagerFactory id); Spring Data JPA. Repositories JPA Project Task @PersistenceContext private EntityManager em; ProjectMember ProjectConfig ProjectHistory Create a repository for each aggregated root

The following example shows matching methods for JPA: Java // ... @PersistenceContext EntityManager entityManager; @Transactional @Test // no expected exception! public void falsePositive() { upd updateEntityInJpaPersistenceContext(); // False positive: an exception will be thrown once the JPA // EntityManager is finally flushed (i.e., in production code) } @Transactional @Test(expected = ...) public void flush is required to avoid false positive in test entityManager.flush(); } // ... // ... @PersistenceContext lateinit var entityManager:EntityManager @Transactional @Test // no expected exception! fun
