How to display data in tree shape?

 　　 　　                                String createTreeJson(List<Resource>         JSONArray rootArray =                        (resource.getParentid() ==                  JSONObject rootObj =                                       JSONObject createBranch(List<Resource>         JSONObject currentObj =         JSONArray childArray =                        (newNode.getParentid() !=  && newNode.getParentid().compareTo(currentNode.getId()) == 0                     JSONObject childObj =             (!             currentObj.put("children"               }


　//2、使用ztree实现树形数据简单无需用递归组装，简单方便

            dep.dep_code,          dep.dep_name,           dep2.dep_code AS parent_Code,                     on dep.pdep_id =   主要返回的对应ztree的id、pId、name,其它属性可自定义，ztree会自动识别组装树形节点的数据；
　　还有就是实体bean中的属性除了定义数据库中的列属性之外，还应该把ztree中的节点属性也定义上
