orm是怎么配置比如菜单资源的上下级的名称的？上下级都是同一个类。

上级是多对一

下级是一对多

里面的名称默认都是类名开头变小写的。

那像这种情况要怎么设置不同名称给他们呢？

有个alias可以指定别名,

orm.single({"departmentId","id"},"Department",{"alias":"myDepartment"})

不过BeetlSQL只支持简单的ORM查询，我不清楚如何完成Hibernate那样的层层映射

也许使用俩个SQL语句，通过orm.single,orm.lazy,可以实现,类似这种，俩个sql互相引用

selectUser
===
    select * from user where user_id=#userId#
    @if(isNotEmpty(departmentId){
          departmentId=#departmentID#
    @}
    @ orm.single({"departmentId":"id"},"selectDepartment","Department");
  

selectDepartment
===
    select * from department  where id=#id#
    @ orm.Many({"id":"department},"selectUser","Department");
