Support for Custom Simple Value Types for @Id

[josephearl]

As a developer
I would like to be able to encapsulate the currently supported ID types like Integer, Long, String etc inside a custom simple value type
So that I can use a domain type for the ID

For instance suppose a products table with a primary key of product ID, where product IDs are strings which must follow a specific format of - for instance - two letters followed by two numbers.

Instead of passing a string around my program as the ID type, I would like to be able to create a ProductId class which enforces the validity of the IDs, and use the ProductId as the ID type in my entity.

Would possible be solved by #574

That really should work with custom conversion. Can you check / provide a reproducer, that it doesn't work?

Thank you that does work. Perhaps the documentation around IDs could be updated to make this clearer and point to the custom conversion docs.
