In the previous section, we have written a custom page tag and referenced it in JSP: PM is actually a paging model, which includes the current page number (pageno), the number of records to be displayed per page (pagesize), and the total number of records (recordcount) and data that meets the paging conditions ). The paging model is as follows: Pagemodel. Java /*** Classname: pagemodel. java * created on 2011 * copyrights 2011 hi.csdn.net/tjcyjd All Rights Reserved. * site: http://hi.csdn.net
