MongoRepository same methods with diferent @Query

Using spring data mongo repository class, how can I do this? I need the same method twice but in one I need to exclude a field.

public interface Person extends MongoRepository<Person, String>{
        
    Optional<Person> findById(String id);

    @Query(fields="{ 'company': 0 }")
    Optional<Person> findById(String id);
}

This doesn't work because I can't have the same method twice, is there a way to do it?

The problem arises when you want to call the method. It would be ambiguous which method is being called.

If you want to use method overloading to have a same name for both of your methods, it is only possible if they have different parameters.

here is an example:

public interface Person extends MongoRepository<Person, String>{
        
    Optional<Person> findById(String id);

    @Query(fields="{ 'company': 0 }")
    Optional<Person> findById(String id, Boolean exclude);
}
