</div>
</body>
</html>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~~~~~~~~~~
