一、导入依赖
<dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.4.1</version>--> </dependency>
二、查询前后增加PageHelper和PageInfo
@Override public AjaxResult selectPageList(Integer currentPage, Integer pageSize) { //增加PageHelper PageHelper.startPage(currentPage,pageSize); List<SysDept> sysDepts = sysDeptMapper.selectPageList(); //增加PageInfo PageInfo<SysDept> info=new PageInfo<>(sysDepts); return AjaxResult.success(info); }
三、返回结果
调用接口
http://localhost:10200/admin/dept/slelectpage?currentPage=2&pageSize=1
