الترقيم (Pagination)

في هذا الدرس

return lists in pages.

الموضوعات المخطط لها

• An unbounded list grows until it breaks the server and the client.
• Use page (starting at 0 or 1; pick one) and size query parameters.
• Cap the size: if the client asks for 10,000, return at most your maximum (for example 100).
• Return the page items plus metadata: page, size, total elements, total pages.
• Spring Data offers Pageable; with the in-memory repository now, implement it by hand and swap later (JNR-P4).
