Java中的JsonObject

Question

原始问题：已解决

我使用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： "headers":{"Status":"","Submission Date":"","Organization Name":"","ID":""}

相反，我需要将输出作为：

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

这可能吗？请指教。请注意我可以将JSON作为javascript变量，如果这更容易吗？

修改

我需要在JSON输出中进行一个更简单的更改。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");

这会生成JSON输出：

{"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

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 );

Answer 2

organizationsHJ.put（“headers”，headers.keySet（））;
