The above is the code of the jsp page. Because it is a pure plug-in test, you can directly copy the code used in the past.

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);
    }</ztree>

 List<ztree> getMenusById(Ztree ztree)  Exception;
//接口</ztree>

"ztreeService"  ZtreeServiceImpl  List queryList(Ztree ztree) =" from Ztree where 1=1 "<string> params =  HashMap<string>(ztree.getId()!=+=" and id = :id ""id" List<ztree> getMenusById(Ztree ztree) =" from Ztree where 1=1 "<string> params= HashMap<string>(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> params= HashMap<string>"id"<ztree> queryZtree =(queryZtree!=&&queryZtree.size()>0=</ztree></string></string></ztree></ztree></ztree></string></string></ztree></string></string>

There is no need to write the dao layer, it is just a query. I will attach the ztree table fields below

I hope it can help everyone. This is the test code when I learn the ztree plug-in again, the annotated version of the ssh framework. I haven’t tried it in other frameworks, but after understanding how to use it, it should be fine. , I believe you are all much better than me. Not a master, just sharing. God, don’t squirt~~~~~~~~~~
