是否可以在 JPA 中使用 window 函数？

Question

I need to use window functions within a Spring Data Repository, is this possible?

I am now using java spring maven and I have no knowledge about the entity table partition in JPA.

My SQL Query

select 
b.q_stop_id as q_stop_id,
b.q_work_day as q_work_day,
b.q_work_end as q_work_end,
