详解jeefast和Mybatis实现二级联动的问题

//	二级联动
@RequestMapping("/all/{gid}")
@RequiresPermissions("platform:classes:all")
public R list1(@PathVariable("gid") int gid){
		Mapmap=new HashMap<>();
		map.put("gid",gid);
	List list1 = classesService.selectByMap(map);
	return R.ok().put("classes", list1);
}

//二级联动
	@RequestMapping("/all")
	@RequiresPermissions("platform:grade:all")
	public R list(){
		Map map = new HashMap<>();
		List list = gradeService.selectByMap(map);
		return R.ok().put("grade", list);
	}
