SpringBoot与PageHelper的整合示例详解
1.PageHelper简介
PageHelper官网地址:
https://pagehelper.github.io/
摘要:com.github.pagehelper.PageHelper是一款好用的开源免费的Mybatis第三方物理分页插件。
PageHelper是一款好用的开源免费的Mybatis第三方物理分页插件，其实我并不想加上好用两个字，但是为了表扬插件作者开源免费的崇高精神，我毫不犹豫的加上了好用一词作为赞美。
原本以为分页插件，应该是很简单的，然而PageHelper比我想象的要复杂许多，它做的很强大，也很彻底，强大到使用者可能并不需要这么多功能，彻底到一参可以两用。但是，我认为，作为分页插件，完成物理分页任务是根本，其它的很多智能并不是必要的，保持它够傻够憨，专业术语叫stupid，简单就是美。
我们将简单介绍PageHelper的基本使用和配置参数的含义，重点分析PageHelper作为Mybatis分页插件的实现原理。
