java - 如何测试 json object1 是 json object2 的子集

Question

我正在寻找一个 JSON 配对库，它支持比较两个 JSON 对象(忽略子顺序)，检查第一个对象是否是另一个对象的子集

Answer 1

我找不到任何答案，所以我编写了自己的算法

public boolean checksubsetobject(JSONObject outputjson,JSONObject inputjson) 抛出 JSONException {

     Iterator<String> inputjsonkeys = inputjson.keys();
    while(inputjsonkeys.hasNext())
    {

     String key = inputjsonkeys.next();
      String val = null;
        try{
             JSONObject inputvalue = inputjson.getJSONObject(key);

             if(outputjson.has(key))
             {
                 try{
                    JSONObject outputvalue = outputjson.getJSONObject(key);
                    if( checksubsetobject(outputvalue,inputvalue) == false)
                        {
                          return false;
                        }
                    }
                 catch(Exception e)
                 {
                     return false;
                 }

             }
             else
             {
                 return false;
             }
        }catch(Exception e){
            val =inputjson.get(key).toString();


        }

        if(val != null){
        if (checksubsetstring(outputjson,key,val)==false)
            {
              return false;
            }
        }

    }

    return true;

}
