I am trying to use Spring Data JPA 1.8 with the Java 8 Date/Time API JSR-310.
Everything seems to work, until I try to get all Vehicles between two LocalDateTimes.
The number of Entities returned seems to only have a loose correlation with the number it should.
Entity
@Repository
public interface VehicleRepository extends JpaRepository<Vehicle, Long> {
List<Vehicle> findByDateTimeBetween(LocalDateTime begin, LocalDateTime end);
}
Repository
@Entity
@Table(name = "VEHICLE")
public class Vehicle implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name = "IDX", nullable = false, unique = true)
@GeneratedValue(strategy = GenerationType.AUTO)
private long vehicleId;
@Column(name = "DATE_TIME", nullable = false)
private LocalDateTime dateTime = LocalDateTime.now();
// Getters and Setters
}

Failing Test Example
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath*:applicationContextTesting.xml"})
@Transactional
public class VehicleRepositoryTest {
@Autowired
private VehicleRepository vehicleRepository;
@Test
public void testVehicleBetween() {
// Given
Vehicle vehicleMarch1Twelve = new Vehicle();
Vehicle vehicleMarch1Eighteen = new Vehicle();
Vehicle vehicleMarch2Five = new Vehicle();
Vehicle vehicleMarch2Six = new Vehicle();
LocalDateTime march1Twelve = LocalDateTime.of(2015, Month.MARCH, 1, 12, 0);
LocalDateTime march1Eighteen = LocalDateTime.of(2015, Month.MARCH, 1, 18, 0);
LocalDateTime march2Five = LocalDateTime.of(2015, Month.MARCH, 2, 5, 0);
LocalDateTime march2Six = LocalDateTime.of(2015, Month.MARCH, 2, 6, 0);
vehicleMarch1Twelve.setDateTime(march1Twelve);
vehicleMarch1Eighteen.setDateTime(march1Eighteen);
vehicleMarch2Five.setDateTime(march2Five);
vehicleMarch2Six.setDateTime(march2Six);
vehicleRepository.save(vehicleMarch1Twelve);
vehicleRepository.save(vehicleMarch1Eighteen);
vehicleRepository.save(vehicleMarch2Five);
vehicleRepository.save(vehicleMarch2Six);
vehicleRepository.flush();
// when
List<Vehicle> allVehicles = vehicleRepository.findByDateTimeBetween(
march1Twelve,
march2Six);
List<Vehicle> allVehicles2 = vehicleRepository.findByDateTimeBetween(
march1Twelve.minusMinutes(2),
march2Six.plusMinutes(2));
List<Vehicle> threeVehicles = vehicleRepository.findByDateTimeBetween(
march1Twelve.plusMinutes(2),
march2Six);
List<Vehicle> twoVehicles = vehicleRepository.findByDateTimeBetween(
march1Twelve.plusMinutes(2),
march2Six.minusMinutes(2));
List<Vehicle> oneVehicles = vehicleRepository.findByDateTimeBetween(
march1Twelve.plusMinutes(2),
march2Six.minusHours(3));
// then
Assert.assertTrue("size was " + allVehicles.size(), allVehicles.size() == 4);
Assert.assertTrue("size was " + allVehicles2.size(), allVehicles2.size() == 4);
Assert.assertTrue("size was " + threeVehicles.size(), threeVehicles.size() == 3);
Assert.assertTrue("size was " + twoVehicles.size(), twoVehicles.size() == 2);
Assert.assertTrue("size was " + oneVehicles.size(), oneVehicles.size() == 1);
Assert.assertTrue(oneVehicles.get(0).getDateTime().equals(march1Eighteen));
}
}
The first List contains 2 elements (should be 4). All other List contain 0 elements!
Given the second request is for a greater timespan than the first.
Can someone tell me what I am doing wrong?
Edit
Thank you @Oliver Gierke for the quick answer.
I was able to fix the issue by adding "org.springframework.data.jpa.convert.threeten" to the packagesToScan property. Now it seems to work properly.
