Is there any annotation for Spring data JPA to not return the entire entity in JSON? (Rest API (SQL))

Code: (It's simple)

@GetMapping("/{id}")
public Optional<Person> getOne(@PathVariable Long id){
    return personRepository.findById(id);
}

Example:

{
   "id": 1,
   "name": "Will",
   "character": {
   "id": 1,
   "name": "Batman",
   "power": 100
    }
 }

Example of how I would like it:
(Only the entity id, without all fields.)

{
   "id": 1,
   "name": "Will",
   "character": {
   "id": 1
    }
 }

For that you can mark those fields as @Transient in entity. Those fields will neither be persisted nor be serialized, de-serialized..
