public Object queryDiseaseDisCode() {List<Map<String,Object>> treeList =new ArrayList<Map<String,Object>>();//查询第一级分类,即:最顶层节点List<Disease> doseaseList = diseaseDao.selectDisCode();for (int i = 0; i
查找全部节点: 查找具体节点的子节点,孙子节点: 上面的图是用java递归树结构运行的效果,和预测的结果相同。接下来是代码实现: import java.util.*;public class LookWord {private ArrayList<TreeBean> treeList = new ArrayList<TreeBean>(); //初始public stat
1、首先需要安装django-mptt python manger.py Django-mptt 2、models.py如下: from django.db import models from mptt.models import MPTTModel class Area(MPTTModel): name = models.
