1、pom依赖

com.github.pagehelper

pagehelper-spring-boot-starter

1.2.3

2、分页配置application.properties

pagehelper.helper-dialect=mysql

pagehelper.reasonable=true

pagehelper.support-methods-arguments=true

pagehelper.params=count=countSql

1)其中pagehelper.reasonable这个属性含义是分页参数合理化，3.3.0以上版本可用

当启用合理化时，如果pageNum>pageSize,默认会查询最后一页的数据。禁用合理化后，当pageNum>pageSize会返回空数据

2)pagehelper.support-methods-arguments

支持通过 Mapper 接口参数来传递分页参数,在开启分页时直接将实体类传入，pageHelper会自动根据 pagehelper.params中设定的参数来进行开启分页的参数映射，例如设置pagehelper.params=pageNum=start;pageSize=limit 则将对象传入startPage(Object o)中时，会自动配置pageNum为start，pageSize为limit

3)pagehelper.params=count=countSql

支持上述的配置的参数配置

3、在原有查询前加一行

PageHelper.startPage(0 , 1); 两个参数类似mysql的limit

@RequestMapping("findByMedicalIDAndRecordType")

public PageInfo> findByMedicalIDAndRecordType(@RequestParam Map map){

PageHelper.startPage(0 , 1);

List> list=checkApplyService.findByMedicalIDAndRecordType(map);

//得到分页的结果对象

PageInfo> personPageInfo = new PageInfo<>(list);

return personPageInfo;

}

4、测试：
