谷粒学院35——教师模块实现分页查询功能

下面实现分页功能。

(1)在EduConfig中配置分页插件

/**
* 分页插件
*/
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor();
}

(2)在EduTeacherController中编写分页功能

    @ApiOperation("分页查询")
    @GetMapping("/pageList/{page}/{limit}")
    public R pageList(@ApiParam(name = "page", value = "当前页码", required = true) @PathVariable Long page,
                      @ApiParam(name = "limit", value = "每页记录数", required = true) @PathVariable Long limit) {
        Page<EduTeacher> teacherPage = new Page<>(page, limit);
        // mp会把结果封装到eduTeacherService中
        eduTeacherService.page(teacherPage, null);
        Long total = teacherPage.getTotal();
        List<EduTeacher> records = teacherPage.getRecords();
        Map map = new HashMap<>();
        map.put("total", total);
        map.put("records", records);
        return R.ok().data(map);
    }
