项目场景：

在一些小程序中会涉及到一个表单中的一个数组对象中夹杂着另一个对象数据,这个被夹杂的数据是from表单内的一组单选或者双选这样的数据,前端转为json对象之后传到后端进行解析

问题描述

首先传进来的对象是这样的格式的

abc:{"a":"0","a":"1","a":"0","a":"0","a":"1","a":"0",abcd={"a":"0","a":"0","a":"0","a":"0"},"a":"0"}

他是对象套对象的格式,有两个需求第一个是内部里面的这个对象需要取出来根据指定名称进行拼接存入一个字段然后和整个对象一起存入到第一个a表内,然后遍历第二个对象根据名称进行业务处理之后依次存入第二个b表内

解决方案：

我采取的时迭代器和for循环实现的,迭代器晒出内部对象,然后放入map内,for循环遍历map进行业务处理,下面是具体的实现步骤

这是简化代码,下面是我具体的业务处理,用的都是比较常见的方法

JSONObject jsonInfo = new JSONObject();
jsonInfo.put("add", houseSafetyContents);

Map<String, Map<String, String>> map = new TreeMap<>(); // 使用TreeMap来存储键值对，保证按照键的自然顺序遍历
Iterator<String> keys = jsonInfo.keys();
while (keys.hasNext()) {
  String key = keys.next();
  JSONObject value = jsonInfo.getJSONObject(key);
  Map<String, String> innerMap = new HashMap<>();
  
  Iterator<String> innerKeys = value.keys();
  while (innerKeys.hasNext()) {
    String innerKey = innerKeys.next();
    String innerValue = value.getString(innerKey);
    System.out.println(innerValue);
    System.out.println(innerKey);
    innerMap.put(innerKey, innerValue);
  }
  
  map.put(key, innerMap);
}

// 按照键的自然顺序遍历键值对
for (Map.Entry<String, Map<String, String>> entry : map.entrySet()) {
  String key = entry.getKey();
  Map<String, String> innerMap = entry.getValue();
  System.out.println("Key: " + key);
  for (Map.Entry<String, String> innerEntry : innerMap.entrySet()) {
    String innerKey = innerEntry.getKey();
    String innerValue = innerEntry.getValue();
    System.out.println(innerKey + " - " + innerValue);
  }
}
