Spring Jdbc embedded database lifecycyle - spring

Question

I am using spring embedded jdbc database configuration in spring context file for Junit testing. I am using in memory database for testing. I am trying to unit test only DAO layer and for unit testing I am using spring container's in memory database.
When I am running Junit test case I am not seeing first test case values in second test case (testAddressCreate in testAddressUpdate test case). I am not using #Before or #After in my Junit for now. I am not sure how spring is creating in memory database and starting it. According to behavior it seems that it is creating or resetting before each test case. Does anyone know about it? Also how can we connect to spring created in memory database. Please suggest.
Spring Configuration is :
<jdbc:embedded-database id="dataSource" type="HSQL">
<jdbc:script location="classpath:createdb.sql" />
Junit test case is :
#ContextConfiguration(locations="classpath:test-context.xml")
#Transactional
public class GenericDaoImplTest extends AbstractTransactionalJUnit4SpringContextTests {
#Autowired
private GenericDao<Address, Long> addressDao;
#Test
public void testAddressCreate() {
Address address = new Address();
address.setAddress1("first address");
address.setCity("First City");
address.setCountry("First one");
address.setPostalCode("22222");
boolean result = addressDao.create(address);
Assert.assertEquals(true, result);
List<Address> listOfAddress = addressDao.findAll();
Assert.assertNotNull(listOfAddress);
for(Address addressTemp : listOfAddress){
System.out.println(addressTemp.getAddress1());
System.out.println(addressTemp.getAddressId());
}
}
#Test
public void testAddressUpdate(){
Address address = new Address();
address.setAddress1("second address");
address.setCity("Second City");
address.setCountry("Second one");
address.setPostalCode("11111");
boolean result = addressDao.create(address);
Assert.assertEquals(true, result);
address.setAddress1("Updated Second Address");
Assert.assertNotNull(addressDao.update(address));
List<Address> listOfAddress = addressDao.findAll();
Assert.assertNotNull(listOfAddress);
for(Address addressTemp : listOfAddress){
System.out.println(addressTemp.getAddress1());
System.out.println(addressTemp.getAddressId());
}
}
}

By default, a #Transactional test method will rollback any changes made to the database during the test method. If you want to change this behavior you need to annotate your method with #Rollback(false). I don't think the documentation is specific about the default behavior, but the Javadocs mentions this here:
Retrieves the TransactionConfigurationAttributes for the specified class which may optionally declare or inherit #TransactionConfiguration. If TransactionConfiguration is not present for the supplied class, the default values for attributes defined in TransactionConfiguration will be used instead.
And the default value defined in TransactionConfiguration for rollback is "true".
These being said, you need something like this to be able to keep the values from the first #Test method in the second one:
#Test
#Rollback(false)
public void testAddressCreate() {
Address address = new Address();
...
}
