Develop the Data Access Tier

Explore how to develop the data access tier by implementing and testing Hibernate data operations including retrieval, insertion, update, and deletion of entities in a one-to-many unidirectional relationship. Understand how to write test cases and use Hibernate Session methods to manage persistent data effectively.

We'll cover the following...

Next, we will look at the data access tier. We will start with the test case for the get all records formula.

Find all records operation

Java
@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration( locations = { "classpath:context.xml" } )
@TransactionConfiguration( defaultRollback = true )
@Transactional
public class PersonDaoImplTest {
	@Autowired
	private PersonDao dao ;
	@Test
	public void testGetAll() {
		Assert.assertEquals(0L, dao.getAll().size());
	}
}

Note how to write the imitating data access operation for the test directly above. The Hibernate 4 Session.createQuery method is used with SQL to retrieve all records ...
