将数据添加到JSONObject

为了得到这个结果：

{"aoColumnDefs":[{"aTargets":[0],"aDataSort":[0,1]},{"aTargets":[1],"aDataSort":[1,0]},{"aTargets":[2],"aDataSort":[2,3,4]}]}

拥有与以下相同的数据：

  {    "aoColumnDefs": [     { "aDataSort": [ 0, 1 ], "aTargets": [ 0 ] },     { "aDataSort": [ 1, 0 ], "aTargets": [ 1 ] },     { "aDataSort": [ 2, 3, 4 ], "aTargets": [ 2 ] }   ]  }

您可以使用以下代码：

    JSonObject jo = new JSonObject();    Collection<JSONObject> items = new ArrayList<JSONObject>();    JSonObject item1 = new JSonObject();    item1.put("aDataSort", new JSonArray(0, 1));    item1.put("aTargets", new JSonArray(0));    items.add(item1);    JSonObject item2 = new JSonObject();    item2.put("aDataSort", new JSonArray(1, 0));    item2.put("aTargets", new JSonArray(1));    items.add(item2);    JSonObject item3 = new JSonObject();    item3.put("aDataSort", new JSonArray(2, 3, 4));    item3.put("aTargets", new JSonArray(2));    items.add(item3);    jo.put("aoColumnDefs", new JSonArray(items));    System.out.println(jo.toString());
