se.plushogskolan.jee.utils.domain.IdHolder
An interface for all entities that can return a long ID. This is supposed to be done by every JPA entity. By having this simple interface we can reuse functionality for all JPA entities. If a method returns an object of type IdHolder, we can cast that to whatever object we expect.


  @Test
  public void testFindById() {


    long id = getRepository().persist(getEntity1());
    IdHolder entity = getRepository().findById(id);
    assertNotNull("Entity is not null", entity);
    assertEquals("Id is correct", id, entity.getId());
  }
