如何使用java读取多个json对象？

我有一个JSON响应，我想将每个元素存储在一个字符串中。由于我不熟悉JSON，因此很难找到解决方案。请给我一个解决方案。 下面是我的json响应

{
    "responseFlag": 1,
    "responseMsg": "Successfully retrieved data",
    "responseObj": [{
            "assets": {
                "asset_since": "",
                "asset_type": "",
                "comments": "",
                "estimated_value": "",
                "material_status": "SINGLE",
                "ownership_of_assets": "",
                "pep": "",
                "source_of_income": ""
            }
        },
        {
            "assets": {
                "asset_since": "",
                "asset_type": "",
                "comments": "",
                "estimated_value": "",
                "material_status": "SINGLE",
                "ownership_of_assets": "",
                "pep": "",
                "source_of_income": ""
            }
        }
    ]
}

我想将每个对象元素存储在一个数组中

我试过的代码如下

 package mytry;

 import java.util.Iterator;
 import org.json.simple.JSONArray;
 import org.json.simple.JSONObject;
 import org.json.simple.parser.JSONParser;
 import org.json.simple.parser.ParseException;


  public class Mytry {


   public static void main(String[] args) {
    // TODO code application logic here

    String response="{\n" +
    "  \"responseFlag\": 1,\n" +
    "  \"responseMsg\": \"Successfully retrieved data\",\n" +
    "  \"responseObj\": [\n" +
    "    {\n" +
    "      \"assets\": {\n" +
    "        \"asset_since\": \"\",\n" +
    "        \"asset_type\": \"\",\n" +
    "        \"comments\": \"\",\n" +
    "        \"estimated_value\": \"\",\n" +
    "        \"material_status\": \"SINGLE\",\n" +
    "        \"ownership_of_assets\": \"\",\n" +
    "        \"pep\": \"\",\n" +
    "        \"source_of_income\": \"\"\n" +
    "      }},\n" +
    "     {\n" +
    "      \"assets\": {\n" +
    "        \"asset_since\": \"\",\n" +
    "        \"asset_type\": \"\",\n" +
    "        \"comments\": \"\",\n" +
    "        \"estimated_value\": \"\",\n" +
    "        \"material_status\": \"SINGLE\",\n" +
    "        \"ownership_of_assets\": \"\",\n" +
    "        \"pep\": \"\",\n" +
    "        \"source_of_income\": \"\"\n" +
    "      }}]}";
    JSONParser parser = new JSONParser();
    try {
        Object obj = parser.parse(response);

        JSONObject jsonObject = (JSONObject) obj;
        //System.out.println(jsonObject.toString());
        System.out.println("json size=="+jsonObject.size());
        System.out.println("hghgfh"+jsonObject.keySet());
         Long sflag = (Long) jsonObject.get("responseFlag");
         String msg=(String) jsonObject.get("responseMsg");
         String resobj=(String) jsonObject.get("responseObj").toString();
        //jsonObject.

        System.out.println("sflag=="+sflag);
        System.out.println("msg=="+msg);
         System.out.println("msg=="+resobj);




  //             JSONArray msg = (JSONArray) jsonObject.get("responseFlag");
  //            Iterator<String> iterator = msg.iterator();
  //            while (iterator.hasNext()) {
  //                System.out.println(iterator.next());
  //            }

  //            for(Iterator iterator = jsonObject.keySet().iterator();     iterator.hasNext();) {
 //    String key = (String) iterator.next();
 //    System.out.println(jsonObject.get(key));
 //}

 //             String asset = (String) jsonObject.get("assets");
 //            System.out.println("session token"+asset);
         //sflag = (Long) jsonObject.get("responseFlag");
        //System.out.println("session sflag"+sflag);

    } catch (ParseException ex) {
       System.out.println(ex);
    }
    }

    }

我需要将每个资产值存储在一个数组中

这是一个伪代码。您可以在此代码中填充缺少的部分

       String json = "{"responseFlag":1,"responseMsg":"Successfully retrieved data","responseObj":[{"assets":{"asset_since":"","asset_type":"","comments":"","estimated_value":"","material_status":"SINGLE","ownership_of_assets":"","pep":"","source_of_income":""}},{"assets":{"asset_since":"","asset_type":"","comments":"","estimated_value":"","material_status":"SINGLE","ownership_of_assets":"","pep":"","source_of_income":""}}]}";

        JSONObject jsonObject = new JSONObject(json); 
        JSONArray jsonArray = jsonObject.getJSONArray("responseObj");


        for(int i=0; i<jsonArray.length(); i++) 
        {
            JSONObject arrayJsonObject  = jsonArray.getJSONObject(i);   
            //insert into your list or array 
        }

String json=“{responseFlag]：1，“responseMsg:”成功检索数据“，”responseObj:“{”资产“：”资产类型“：”注释“：”估计值“：”材料状态“：”单一“，”资产所有权“：”pep“，”收入来源“：”}，{”资产“：{”资产“：”资产类型“：”注释“，”估计值“：”材料状态：“单一”、“资产所有权”：“政治公众人物”：“收入来源”：“}}]}”；
JSONObject JSONObject=新的JSONObject（json）；
JSONArray JSONArray=jsonObject.getJSONArray（“responseObj”）；
如果您使用的是json-simple-1.1.1 jar，则为（int i=0；i）

        JSONParser parser = new JSONParser();
        try {
            Object obj = parser.parse(response);
            JSONObject jsonObject = (JSONObject) obj;
            //System.out.println(jsonObject.toString());
            System.out.println("json size==" + jsonObject.size());
            System.out.println("hghgfh" + jsonObject.keySet());
            JSONArray jsonArray = (JSONArray)jsonObject.get("responseObj");
            for(int i=0; i<jsonArray.size(); i++)
            {
                JSONObject arrayJsonObject  = (JSONObject) jsonArray.get(i);
                JSONObject assets = (JSONObject) arrayJsonObject.get("assets");
                // read the assets to store
            }
        }catch (Exception e){

        }

JSONParser=newjsonparser（）；
试一试{
objectobj=parser.parse（响应）；
JSONObject JSONObject=（JSONObject）对象；
//System.out.println（jsonObject.toString（））；
System.out.println（“json大小=”+jsonObject.size（））；
System.out.println（“hghgfh”+jsonObject.keySet（））；
JSONArray JSONArray=（JSONArray）jsonObject.get（“responseObj”）；
对于（int i=0；i实际的问题是什么？有需要是很好的，但这本身并不是一个有效的问题。“资产”：{“资产自”：“资产类型”：“评论”：“估计价值”：“材料状态”：“单一”，“资产所有权”：“pep”：，“收入来源”：“}}，{“资产”：“{”资产自“：”资产类型“：”注释“：”估计价值“：”材料状态“：”单一“，”资产所有权“：”pep“：”收入来源“：”}我希望此响应对象存储在arrayHi Praveen中，我使用json-simple-1.1.1 jar。我需要更改jar吗？如果是json simple jar，请按照下面的Jaycee回答。我使用json.jarWelcome。但是总体概念是相同的。从jsonObject获取jsonArray并迭代它。
        JSONParser parser = new JSONParser();
        try {
            Object obj = parser.parse(response);
            JSONObject jsonObject = (JSONObject) obj;
            //System.out.println(jsonObject.toString());
            System.out.println("json size==" + jsonObject.size());
            System.out.println("hghgfh" + jsonObject.keySet());
            JSONArray jsonArray = (JSONArray)jsonObject.get("responseObj");
            for(int i=0; i<jsonArray.size(); i++)
            {
                JSONObject arrayJsonObject  = (JSONObject) jsonArray.get(i);
                JSONObject assets = (JSONObject) arrayJsonObject.get("assets");
                // read the assets to store
            }
        }catch (Exception e){

        }
