Java 中的 JsonObject

Question

原问题：已解决

我正在使用 JsonObject/JsonArray 从控制器生成 Json:

    JSONObject headers = new JSONObject();
    headers.put("ID", "");
    headers.put("Organization Name", "");
    headers.put("Submission Date", "");
    headers.put("Status", "");

    JSONObject organizationsHJ = new JSONObject();
    organizationsHJ.put("headers", headers);

    array.add(organizationsHJ );

这会产生 JSON 作为： "headers":{"Status":"","Submission Date":"","Organization Name":"","ID":""}

相反，我需要得到如下输出：

"headers":[  "ID",  "Organization Name",  "Submission Date",  "Status"  ]

这可能吗？请指教。请注意，我也可以将 JSON 作为 javascript 变量，如果这样更容易吗？

编辑：

我需要对 JSON 输出进行更简单的更改。这是我的代码：

JSONObject notifications = new JSONObject();
notifications.put("id", "1");
notifications.put("description", "Notification 1");
notifications.put("createdTimestamp", "2015-05-12T18:15:28.237Z");
notifications.put("startTimestamp", "2015-05-25T18:30:28.237Z");
notifications.put("endTimestamp", "2015-06-13T12:30:30.237Z");
notifications.put("active", "true");

这生成 JSON 输出为：

{"data":{"id":"1","createdTimestamp":"2015-05-12T18:15:28.237Z","description":"Notification 1","startTimestamp":"2015-05-25T18:30:28.237Z","active":"true","createdId":"251","endTimestamp":"2015-06-13T12:30:30.237Z"}}

相反，我希望它生成为：

{"data":["id":"1","createdTimestamp":"2015-05-12T18:15:28.237Z","description":"Notification 1","startTimestamp":"2015-05-25T18:30:28.237Z","active":"true","createdId":"251","endTimestamp":"2015-06-13T12:30:30.237Z"]}

Answer 1

organizationsHJ.put("headers", headers.keySet());

Answer 2

headers 应该是 JSONArray，而不是 JSONObject。对象是一组名称到值的映射，数组是线性集合。

JSONArray headers = new JSONObject();
headers.add("ID");
headers.add("Organization Name");
headers.add("Submission Date");
headers.add("Status");

JSONObject organizationsHJ = new JSONObject();
organizationsHJ.put("headers", headers);

array.add(organizationsHJ );
