java - Single table per class hierarchy without discriminator column -

-

i have existing table without discriminator column , need map single table hierarchy, how map this? here table

vehicle ======== vehicle_id manufacturer load_capacity passenger_capacity

i have 3 classes 

vehicle.java vehicleid; manufacturer;  transportationvehicle.java loadcapacity;  passengervehicle.java passengercapacity;

one way use @mappedsuperclass on vehicle class , map transportationvehicle , passengervehicle same table.

this way inherit mapped fields vehicle without having map entity.
