This article introduces the relevant knowledge of "what is the configuration mode of Spring Boot Jpa paging query". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations.

This is an abandoned interface.

Sort sort = new Sort (Sort.Direction.DESC, "Fields in bean Class"); / / descending sort of creation time Pageable pageable = new PageRequest (pageNumber,pageSize,sort)

The above usage is no longer supported in the latest SpringBoot. Here is a simple paging query demo

Persistence layer configuration

Public interface OrderDao extends JpaRepository {/ / order database persistence Page findByOrderstatus (String status,Pageable pageable);}

Controller layer writing method

@ RequestMapping (value = "/ test1") public Stream findAllOrder (@ RequestParam ("status") String status, @ RequestParam ("page") Integer page) {/ / Jpa paging query Sort sort = Sort.by (Sort.Direction.DESC, "orderdate"); / / sort by order date. Orderdate is a variable in OrderBean, not a field (*) Pageable pageable = PageRequest.of (page,3,sort) in the database. / / page starts at 0. 3 refers to the size of each page, which means to sort paging queries by order date, querying three data return orderDao.findByOrderstatus (status,pageable) .get ();} at a time.
