Examples of org.springframework.orm.jpa.EntityManagerProxy

org.springframework.orm.jpa.EntityManagerProxy
Subinterface of {@link javax.persistence.EntityManager} to be implemented byEntityManager proxies. Allows access to the underlying target EntityManager.
This interface is mainly intended for framework usage. Application code should prefer the use of the {@link javax.persistence.EntityManager#getDelegate()}method to access native functionality of the underlying resource. @author Juergen Hoeller @since 2.5

    EntityManager proxy = (EntityManager) proxyFactoryBean.getObject();
    assertSame(proxy, proxyFactoryBean.getObject());
    assertFalse(proxy.contains(o));


    assertTrue(proxy instanceof EntityManagerProxy);
    EntityManagerProxy emProxy = (EntityManagerProxy) proxy;
    try {
      emProxy.getTargetEntityManager();
      fail("Should have thrown IllegalStateException outside of transaction");
    }
    catch (IllegalStateException ex) {
      // expected
    }


    TransactionSynchronizationManager.bindResource(mockEmf, new EntityManagerHolder(mockEm));
    try {
      assertSame(mockEm, emProxy.getTargetEntityManager());
    }
    finally {
      TransactionSynchronizationManager.unbindResource(mockEmf);
    }
