The use of Mybatis paging plugin PageHelper

public PageInfo<Goods> findByPage(Goods goods, Date createtimeStart, Date createtimeEnd, int pageNo, int pageSize) {
		PageHelper.startPage(pageNo, pageSize);
		Map m = ObjAnalysis.ConvertObjToMap(goods);
		List<Goods> goodsList = goodsMapper.getAll(m);

		PageInfo<Goods> PageInfGoods = new PageInfo<>(goodsList);

		return PageInfGoods;
	}

        @RequestParam(value = "size", defaultValue = "15") Integer size) {
    Sort sort = new Sort(Direction.DESC, "id");

Get the Pageable object directly

@RequestMapping(value = "", method=RequestMethod.GET)
public Page<Blog> getEntryByPageable(@PageableDefault(value = 15, sort = { "id" }, direction = Sort.Direction.DESC)
    Pageable pageable) {
    return blogRepository.findAll(pageable);
}	

Sort by multiple fields

Order order2 = new Order(Direction.DESC, "age");  
Order order3 = new Order(Direction.ASC, "pgrade");  
Order order = new Order(Direction.DESC, "dnum");
