JAVA JSONObject在数组中添加新元素（JSONArray）

我需要在JSONArray中添加一个元素，但是“append”方法会创建多个元素 数组改为添加一个元素

最简单的方法是什么

我使用JUnit创建了以下示例代码，只是为了隔离我的问题

import org.codehaus.jettison.json.JSONArray;
import org.codehaus.jettison.json.JSONException;
import org.codehaus.jettison.json.JSONObject;
import org.junit.Before;
import org.junit.Test;

public class JettisonJSONOperations {

   JSONObject jsonObject = new JSONObject();

   @Before
   public void preCreateJsonObject (){

       try {

           jsonObject.put("groupName","administrators");

           JSONArray members = new JSONArray();
           members.put("edward");
           members.put("richard");
           members.put("john");

           jsonObject.put("members", members);

       } catch (JSONException e) {
           e.printStackTrace();
       }

       System.out.println(jsonObject.toString());
   }

   @Test
   public void addingElementToJSONArray (){

       try {

           jsonObject.append("members", "batman");

       } catch (JSONException e) {
           e.printStackTrace();
       }

       System.out.println(jsonObject.toString());
   }
}

输出：

{"groupName":"administrators","members":["edward","richard","john"]}
{"groupName":"administrators","members":[["edward","richard","john"],"batman"]}

Process finished with exit code 0

在阅读了大量关于抛弃问题的评论之后，我决定将抛弃JSONObject库更改为org.json

发件人：

输出：

{"groupName":"administrators","members":["edward","richard","john"]}
{"groupName":"administrators","members":["edward","richard","john","batman"]}

而不是

jsonObject。附加（“成员”、“蝙蝠侠”）它应该是
jsonObject。getJSONArray（“成员”）.put（“蝙蝠侠”）您正在附加到JSONObject；）啊好。。我还需要一步。。这很有效，谢谢@pyerwin！然而，在我的具体案例中，我发现了一些关于抛弃的问题，比如使用Camel和CXF的JsonProvider，所以我决定将其从org.json更改为Jackson和JSONObject。
