JPA enum mapping by explicit getId()

for enum type you can choose EnumType.ORDINAL or EnumType.STRING. Going for string is definetely better because ordinal mandates that you never ever change the order of definition of the enum-types. On the other hand string also makes the DB entry bigger as necessary (taking the constant name, which can be quite long).

So I want to use an explicit mapping (that JPA uses getId() method).

How or is it possible with JPA to define a custom method of an java enum type?

It is sorta covered in the JavaRanch Style Guide.
