使用java中的哈希表创建json数组

我对如何使用JSONObject（）或google的gson库从java中的哈希表构造关联数组有点困惑

在此感谢您的帮助

    JSONObject message = new JSONObject();
    Map<String,String> responseData = new Hashtable<String, String>();

[……]

结果:

{"submissions":{"vote1":"2","vote7":"1","vote25":"1","vote6":"1","vote13":"1","vote9":"1","vote11":"1"}}

预期结果：

{"submissions":[{"vote1":"2"},{"vote7":"1"},{"vote25":"1"},{"vote6":"1"},{"vote13":"1"},{"vote9":"1"},{"vote11":"1"}]}

想出来了

  JSONObject message = new JSONObject();
  ArrayList<Map<String,String>> responseData = new ArrayList<Map<String,String>>();
  User user = new User(request);

哦，好的，我看到了更新。正确，这是一个带有一个字段的对象列表，没有仔细阅读您的更新。

{"submissions":[{"vote1":"2"},{"vote7":"1"},{"vote25":"1"},{"vote6":"1"},{"vote13":"1"},{"vote9":"1"},{"vote11":"1"}]}

  JSONObject message = new JSONObject();
  ArrayList<Map<String,String>> responseData = new ArrayList<Map<String,String>>();
  User user = new User(request);

    while (results.next()) {
        Map<String,String> tmpdata = new Hashtable<String, String>();
        tmpdata.put("vote" + results.getString("submission_id"), results.getString("counter"));
        responseData.add(tmpdata);
    }

    message.put("submissions", responseData);
