How to use Spring CrudRepository with composite key?

Question

SQL

The repository is auto-implemented from the view interface

@Repository
CrudRepository<Obj, ID>

parameterized by the actual object and key type. If I really don't want to introduce a surrogate long-key with auto-increment in the table, how can I make the repository work with a composite key of two Integer and String fields?
Is it possible to do something like your own key class

class Id {
Integer parent_id;
String name;
}

Are there any solution templates? The task is quite typical, but, apparently, because of my English, Google refuses to cooperate with me.
