Polymorphic list elements in Spring configuration?

Question

Is there an easy way to have polymorphic list elements in a configuration? E.g. for the following application.yaml:

Vehicles:
  one:
    type: Bicycle
    id: 4711
    bell: ringring
  two:
    type: Car
    id: 4712
    horn: toot

I'd like Spring to create Java objects of these classes (grossly simplified):

List<Vehicle>
class Vehicle { int id; }
class Bicycle extends Vehicle { String bell; }
class Car extends Vehicle { String horn; }

The solutions I have seen require duplication of the classes' attributes in another class, which I'd like to avoid:

• The Builder approach is five years old, so maybe it's not the best answer anymore?
• It may be possible to use a Converter approach that works on whatever Spring's representation of a non-String property is. I haven't found a working example yet, though. I know I could make something happen by writing a Converter, but any changes in the Vehicle subclasses would then require matching changes in the Converter so I don't like that; but is there a simpler way?

I know Spring's configuration annotations and what their purpose is, but I don't have full mastery of what they do exactly and how they interact, so please give me enough details to piece working code together, thanks ;-)
