springboot+mybatisplus+pagehelper

虽然mybatisplus具有分页功能，但是更习惯使用PageHelper这个分页插件

Pom文件

Pom中引用了MyBatis的启动器，因此在pageHelp的依赖中应该排除  mybtais和mybatis-spring，以免jar包冲突。

完成Pom配置后，再配置pagehelper的属性文件

pagehelper.helper-dialect=mysql
pagehelper.reasonable=true
pagehelper.support-methods-arguments=true
pagehelper.pageSizeZero=true
pagehelper.params=count=countSql

至此，配置完成，即可以使用mybatisplus自带的分页，也可使用pagehelper的分页功能
