一、后台代码:
1.1 controller层代码
@RequestMapping("/xxxxxx") public String showInformationCode(String pageNum ,Model model,HttpServletRequest request){ String id = (String)request.getSession().getAttribute("Id"); if(pageNum == null){ pageNum="1"; } int parseInt = Integer.parseInt(pageNum); if (StringUtils.isBlank(id)) { return null; } Page<Test> selectTestListById = informationService.selectTestListById(id ,parseInt);//jpa的分页查询,parseInt(第几页) model.addAttribute("selectTestListById ",selectTestListById ); return "test"; }
1.2 service层代码
public static final int PAGE_SIZE = 10; //全局变量PAGE_SIZE(每页显示的数据条数) /** * 分页查询 * @param csdbId * @param pageable * @return */ public Page<Test> selectTestListByCsdbId(String id ,int pageNumber) { PageRequest buildPageRequest = BuildPageRequest(pageNumber, PAGE_SIZE); Page<Test> findById = testMapper.findById(id, buildPageRequest); return findById ; } public static PageRequest buildPageRequest(int pageNumber, int pagzSize){ return new PageRequest(pageNumber - 1, pagzSize, null); }
1.3 mapper层代码
public interface CsdbSetDmInformationCodeMapper extends JpaRepository<CsdbSetDmInformationCode, String>{ /** * 分页 */ Page<Test> findById(String id ,Pageable pageable); //批量删除 @Transactional @Modifying @Query(value="delete from tablre where id in ?1 ",nativeQuery=true) int deleteByPrimaryKeys(List<String> ids); }
这样传入前台的数据就只有10条,直到下一次请求的到来,在根据传入的pageNum(页数)来确定传入前台的数据(eg:每页的条数我是通过全局变量写死了的,可以自行修改)
二、前台使用layui的layPage插件来实现分页
2.1 首先要在页面上引入layui的js和css(也可直接引用layPage.js),layui的下载地址:http://res.layui.com/download/layui/layui-v2.0.2.zip
2.2 前台test.html页面
