Disable MySQL Foreign Key During JUnit Test

Sometimes in our integration tests, we don't want the foreign keys constraints, how to address this? look at my test for example:

@RunWith(SpringTestRunner.class)
@DataLoader(filePaths = { "fixture/bdbslipUpdates.xls" }, loaderType = LoaderType.EXCEL)
@ContextConfiguration(locations = "classpath*:applicationContext.xml")
@ActiveProfiles("test")
@TransactionConfiguration(transactionManager = "transactionManager")
@Transactional
public class DefaultBdbslipUpdaterTest {

	@Autowired
	private DefaultBdbslipUpdater bdbslipUpdater;

	@Autowired
	private IBasSyncDao sdao;
	
	/**
	 * Concern: performance.
	 */
	@Before
	public void disableForeignKey(){
		Session session = sdao.currentSession();
		session.doWork(new Work(){
			@Override
			public void execute(Connection connection) throws SQLException {
				Statement s = connection.createStatement();
				s.execute("SET @@foreign_key_checks = 0;");
				s.close();
			}
		});
	}
	
	@After
	public void enableForeignKey(){
		Session session = sdao.currentSession();
		session.doWork(new Work(){
			@Override
			public void execute(Connection connection) throws SQLException {
				Statement s = connection.createStatement();
				s.execute("SET @@foreign_key_checks = 1;");
				s.close();
			}
		});
	}

Note that 

(1) we use easy test framework and hibernate in this test, pay attention to how we get the JDBC Connection via Hibernate Session.

(2) Different databases have different syntax to disable/enable REFERENTIAL INTEGRITY, our example is FOR MYSQL ONLY.
