Spring Data Neo4J @Indexed(unique = true) not working
- by Markus Lamm
I'm new to Neo4J and I have, probably an easy question.
There're NodeEntitys in my application, a property (name) is annotated with @Indexed(unique = true) to achieve the uniqueness like I do in JPA with @Column(unique = true).
My problem is, that when I persist an entity with a name that already exists in my graph, it works fine anyway.
But I expected some kind of exception here...?!
Here' s an overview over basic my code:
@NodeEntity
public abstract class BaseEntity implements Identifiable
{
@GraphId
private Long entityId;
...
}
public class Role extends BaseEntity
{
@Indexed(unique = true)
private String name;
...
}
public interface RoleRepository extends GraphRepository<Role>
{
Role findByName(String name);
}
@Service
public class RoleServiceImpl extends BaseEntityServiceImpl<Role> implements
{
private RoleRepository repository;
@Override
@Transactional
public T save(final T entity) {
return getRepository().save(entity);
}
}
And this is my test:
@Test
public void testNameUniqueIndex() {
final List<Role> roles = Lists.newLinkedList(service.findAll());
final String existingName = roles.get(0).getName();
Role newRole = new Role.Builder(existingName).build();
newRole = service.save(newRole);
}
That's the point where I expect something to go wrong!
How can I ensure the uniqueness of a property, without checking it for myself??
THANKS IN ADVANCE FOR ANY IDEAS!!
P.S.: I'm using neo4j 1.8.M07, spring-data-neo4j 2.1.0.BUILD-SNAPSHOT and Spring 3.1.2.RELEASE.
