    List<Employee> findCustomEmployees(String firstName, Sort sort);

}

Spring Data JPA will turn this custom query into a JPA query when provided not just with a criteria (firstName) but also a custom sort via findCustomEmployees("Alice", Sort.by("lastName"))…

Here's some inside baseball for you: the Spring teams do their level-headed best to be cohesive, to align on core themes, and to make Spring better than the sum of its parts.
