Query with composite PK collection via spring data (Hibernate JPA)

I have entity class User with composite key via @IdClass annotation

@Entity
@IdClass(UserId.class)
public class User {

    @Id
    private String name;

    @Id
    private String surname;

    private boolean active;

}

Composite key:

@Data
public class UserId implements Serializable {
    private String name;
    private String surname;
}

I use Spring Data with hibernate JPA under hood. Therefore I have repo interface:

public interface UserRepo extends JpaRepository<User, UserId> {

}

And I'd like to get all active users from db by list of concrete names and surnames. E.g. I'd like to use method like this

List<User> findAllByActiveTrue(List<UserId> ids);

How can I do query for this requirement via Spring Data or JPQL?

You can use @Embeddable & @EmbeddedId for composite primary key

@Embeddable
public class UserId implements Serializable {
    private String name;
    private String surname;
}

@Entity
public class User {

    @EmbeddedId
    private UserId userId;
    ...
}

Then query like 

List<User> findByUserIdInAndActiveTrue(List<UserId> ids);

A good tutorial about @Embeddable & @EmbeddedId here
