[2.0.3] Register Entity Classes

[Андрей Гришин]

Hello!

I little bit confused while trying to register my entities classes.

I have my POJOs structure, which i need to bind, like this:

public class SliderEntity extends OEntity {

private double min;

private double max;

private double value;

private String style;

private transient BigDecimal trans;

...

}

public class ODateSignature {

private Date datetime;

...

}

@Entity

public abstract class OEntity {

private String name;

@Embedded

private ODateSignature signature;

@Embedded

private List<OEntity> versions;

@OVersion

private Object version;

...

}

Next step i connected to database and tried to:

database.setAutomaticSchemaGeneration(true);

database.getEntityManager().registerEntityClass(SliderEntity.class);

...and then, when i tried to save my object, i've got error:

com.orientechnologies.orient.core.exception.OSerializationException: Linked type [class org.orient.store.object.ODateSignature:23.02.15 12:16] cannot be serialized because is not part of registered entities. To fix this error register this class

As i inderstood next, i can try to do:

database.setAutomaticSchemaGeneration(true);

database.getEntityManager().registerEntityClasses(SliderEntity.class, true); // register my entities recursively

but after this, apart from error above, saving my object occurs in issue, where i have database scheme structure like this:

So, i saw that transient field "trans" was registered, which i really do not need to store in database, and also my ODataSignature still was not registered for binding.

Please, tell me, am I understand something wrong or this are bugs?

Thanks,

Andrey
