使用MongoDB CustomRepository和嵌套数据访问的Spring Boot

Question

我正在尝试通过创建User接口从WorkDate和CustomUserWorkdateRepository存储库中构建CustomRepository。我明确只想从WorkTime访问用户特定的WorkDate。因此，我想创建一个查询，在其中为WorkDate的属性year，month，day指定一个属性，并仅返回WorkTime对象（例如Graphql ）。那有可能吗？那么CustomUserWorkDateRepository会是什么样子？

public interface CustomUserWorkdateRepository extends MongoRepository<User, String> {
    ...?
}

public interface WorkDateRepository extends MongoRepository<WorkDate, Integer> {
    public List<WorkDate> findByYear(User user, Integer year);
    public List<WorkDate> findByYearAndMonth(User user, Integer year, Integer month);
}

public class WorkDate {
    public int year;
    public int month;
    public int day;
    public WorkTime workTime;
}

public class WorkTime {
    public Date startTime;
    public Date endTime;
    public Date workTime;
    public Date pauseTime;
}

public interface UserRepository extends MongoRepository<User, String> {
    public User findByFirstName(String firstName);
    public List<User> findByLastName(String lastName);
}

public class User {
    @Id
    public String id;
    public String firstName;
    public String lastName;
...

}
