I have a simple test as below
public class TestDS extends TestCase{
private final LocalServiceTestHelper helper =
new LocalServiceTestHelper(new
LocalDatastoreServiceTestConfig());
@Before
public void setUp() {
helper.setUp();
}
@After
public void tearDown() throws Exception{
Thread.sleep(100);
helper.tearDown();
}
public void testWithoutTransaction() throws Exception{
DatastoreService ds =
DatastoreServiceFactory.getDatastoreService();
doTest(ds, null);
}
public void testWithTransaction() throws Exception{
DatastoreService ds =
DatastoreServiceFactory.getDatastoreService();
Transaction txn = ds.beginTransaction();
doTest(ds, txn);
txn.commit();
}
public void doTest(DatastoreService ds, Transaction txn) throws
Exception{
Key parentKey = KeyFactory.createKey("parent", "default");
Entity entity = new Entity("Entity01", parentKey);
entity.setProperty("prop01", "Property 01");
Key key = ds.put(txn, entity);
Entity entity2 = ds.get(txn, key);
System.out.println(entity2.getProperty("prop01"));
}
}
For the test testWithoutTransaction, it run successful.
However, the test testWithTransaction, exception
EntityNotFoundException is raised at line
Entity entity2 = ds.get(txn, key);
Why we can not get the entity we just put into datastore within a
transaction?
Please help.
Thanks in advance.
