在有多种组合的情况下，如何最好地使用Spring JPA findByXXX？

public class DynamicQuery {

    public static Specification<MyEntity> buildQuery(String param1, String param2) {
        return (root, query, builder) -> {
            List<Predicate> predicates = new ArrayList<>();

            if (param1 != null) {
                predicates.add(builder.equal(root.get("param1"), param1));
            }

            if (param2 != null) {
                predicates.add(builder.equal(root.get("param2"), param2));
            }

            return builder.and(predicates.toArray(new Predicate[0]));
        };
    }
}

@Repository
public interface MyEntityRepository extends JpaRepository<MyEntity, Long> {

    List<MyEntity> findByParams(String param1, String param2, ...);

    default List<MyEntity> findByParams(String param1, String param2) {
        return findAll(DynamicQuery.buildQuery(param1, param2));
    }
}

@Service
public class MyEntityService {

    @Autowired
    private MyEntityRepository myEntityRepository;

    public List<MyEntity> getByParams(String param1, String param2) {
        return myEntityRepository.findByParams(param1, param2);
    }
}
