上面呢,是jsp页面的代码,因为是纯插件测试,可以直接复制过去使用的,

action层代码,可以直接复制使用
    public void getMenusById(){
        List<Ztree> list=null;try {
            list=ztreeService.getMenusById(ztree);
        } catch (Exception e) {
            e.printStackTrace();
        }super.writeJson(list);
    }
 List<Ztree> getMenusById(Ztree ztree)  Exception;
//接口
"ztreeService"  ZtreeServiceImpl  List queryList(Ztree ztree) =" from Ztree where 1=1 "<String, Object> params =  HashMap<String, Object>(ztree.getId()!=+=" and id = :id ""id" List<Ztree> getMenusById(Ztree ztree) =" from Ztree where 1=1 "<String,Object> params= HashMap<String,Object>(ztree.getId()==||ztree.getId().equals(""+=" and pid is null "+= " and pid = :id ""id"<Ztree> queryZtree =<Ztree> list= ArrayList<Ztree>"true"  queryBoolean(Ztree ztree)  flag== " from Ztree where pid = :id "<String,Object> params= HashMap<String,Object>"id"<Ztree> queryZtree =(queryZtree!=&&queryZtree.size()>0=

dao层就不用写了吧,只是一个查询,下面我把ztree的表字段附上

希望可以帮到大家,这就是我再学习ztree插件时的测试代码,ssh框架注解版,在其他框架里还没有试过,但是了解了使用方法,应该都没问题,我相信你们都比我强的多。不是大神,只是分享一下。大神勿喷~~~~~~~~~~
