一、场景介绍
在工作过程中，需要去调另一个系统的接口，获取机构数据，在得到机构数据之后，需要对数据进行遍历然后根据条件获得自己想要的数据，下面我们看代码。
二、代码示例
我们先通过postman来看一下返回的数据结构,可以看出数据关系是父子级,父级有一个children属性,但是最低级没有children属性,通过这个关系我们可以对其遍历,上代码

三、代码实现
private List<Map<String, Object>> getDataList(List<Map<String, Object>> data, List<Map<String, Object>> list) {
//0102 0103 0104 开始遍历
for (int i = 0; i < data.size(); i++) {
//先筛选条件 符合添加到list里面
if (data.get(i).get("deptType").equals(regionTypeUtil.QXQ_LEVEL) ||
data.get(i).get("deptType").equals(regionTypeUtil.SQZBM_LEVEL)) {
Map map = new HashMap<String, Object>();
map.put("orgCode", data.get(i).get("orgCode"));
map.put("orgName", data.get(i).get("label"));
list.add(map);
}
//如果children不为空,递归调用
if (data.get(i).get("children") != null) {
List<Map<String, Object>> datac = (List<Map<String, Object>>) data.get(i).get("children");
getDataList(datac,list);
}
}
return list;
}
