I am developing a Spring Boot app and I am faced with the following situation:

I have x and y entities, but the fields of these entities are exactly the same, and because of this they both use the same DTO (the only difference is that they have different names and both have their own database tables). This situation results that I currently have two identical controllers.

For business reasons, they have to be two separate entities, even though they are the same fields.

What is the correct procedure in this case?

Even though it is code duplication, do I keep both controllers so that one controller can be responsible for only one entity?

Or can I somehow make it so that I can use one controller for both entities, with a dynamic path, and by highlighting the entity type in the path, I can differentiate which service implementation it uses (because the service interface is the same, the two implementations differ in a few details, and one goes to table x and the other to the table y)?
