My DB is postgres, how can I contribute/replace de PostgresPkGenerator with my
own implementation to genera UUID's as PK's:
public class PcExpressPosUUIDPkGenerator extends PostgresPkGenerator {
public PcExpressPosUUIDPkGenerator(@Inject PostgresAdapter adapter) {
super(adapter);
}
@Override
public Object generatePk(DataNode arg0, DbAttribute attribute) throws
Exception {
if ( attribute.getType() == java.sql.Types.OTHER)
return java.util.UUID.randomUUID();
else if (attribute.getType() == java.sql.Types.VARCHAR)
return java.util.UUID.randomUUID().toString();
else
return super.generatePk(arg0, attribute);
}
}
I tryied this in a new Module:
ServerModule.contributePkGenerators(binder).put(PostgresAdapter.class.getName(),
PcExpressPosUUIDPkGenerator.class);
But when trying to create my first context get this error:
org.apache.cayenne.di.DIRuntimeException: DI container has no binding for key
<BindingKey: org.apache.cayenne.dba.postgres.PostgresAdapter>
