ssm框架+PageHelper插件實(shí)現(xiàn)分頁查詢功能
更新時(shí)間：2021年06月09日 16:10:05 作者：姜飛祥
今天小編教大家如何通過ssm框架+PageHelper插件實(shí)現(xiàn)分頁查詢功能，首先大家需要新建一個(gè)maven工程引入jar包，本文通過實(shí)例代碼給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友參考下吧
通過搭建ssm框架，然后通過mybatis的分頁插件pagehelp進(jìn)行分頁查詢。
源碼：https://gitee.com/smfx1314/pagehelper
看一下項(xiàng)目結(jié)構(gòu)：
首先創(chuàng)建一個(gè)maven工程，pom中引入相關(guān)jar包

pom.xml中引入page分頁的jar包

jar包這里就引入完了。下面引入配置文件
