Generic entity deserialization exception #249

well, looks like JaVers thinks that type of id is Serializable, but in fact it is Integer. I will check what we can do about it. |
|
I've tried to reproduce this exception but without success, could you push failing test which would reproduce this issue? |

Maybe you were using InMemoryRepository? I have the same bug when using the JaversSqlRepository: public abstract class AbstractEntity<T extends Serializable> {
@Id
protected T id;
public abstract T getId();
public abstract void setId(final T id);
}@Entity
public class Account extends AbstractEntity<String> {
@Override
public String getId() {
return id;
}
@Override
public void setId(final String id) {
this.id = id;
}
}Configuring Javers and reproducing the bug using SqlRepository (on MSSQL Server): public static void main(final String[] args) {
final Javers javers = JaversBuilder.javers().
registerJaversRepository(SqlRepositoryBuilder.sqlRepository().
withConnectionProvider(() -> DriverManager.getConnection(
dbUrl, dbUser, dbPw)).
withDialect(DialectName.MSSQL).
build()).
build();
final Account acc = new Account();
acc.setId("1");
javers.commit("User", acc);
javers.commit("User", acc);
}The exception does not occur on the first commit. The entity needs to be present in the snapshot-table. Does not happen with InMemoryRepository. Happens with MappingStyle FIELD and BEAN. |

Hi all,
I'm having the following generic base class:
and an implementation
I get the following exception when saving a
Fooentity:Any idea why it can figure out the type it has to deserialize into?
