后台讲师管理模块-分页查询
讲师分页功能
1.配置mp分页插件(分页插件不能少，只有有了插件，分页效果才会有)
/**
*分页插件
*/
@Bean
public Paginationalnterceptor
paginationlnterceptor() {
return new Paginationlnterceptor();
}
2.编写讲师分页查询接口的方法
@GetMapping( "pageTeacher/{current}/{limit}" ) → current代表当前页, limit代表每页记录数
public R pageListTeacher(@PathVariable long current,
@PathVariable long limit) {
//创建page对象
Page<Eduteacher> pageTeacher = new Page<>( current, limit) → 1代表当前页, 3.代表每页的记录数
/调用方法实现分页
//调用方法的时候，底层封装，把分页所有数据封装到pageTeacher对象里面
teacherService. page(pageTeacher, wrapper: null) :
long total = pageTeacher. getTotal(): //总数记录
List<Eduteacher> records = pageTeacher. getRecords() : //数据list集合
// Map map = new HashMap () :
// map. put ( "total" , total ) :
// map. put ( "rows" , records) :
// return R. ok(). date(map)
return R. ok() . date( "total" , total) . date( "rows" , records) :
}
//刷新，点击方法
/eduservice/teacher/pageTeacher/{current}/{limit} ,其中俩个参数当前页current
1 , 每页limit 2 ,然后最后点击Try it out！
