我想创建一个json数据来解析服务为字符串，例如http://xyzabc.com/pos/getstatus?parse=mystring
该字符串必须包含以下数据。我在arraylist中将这些数据作为同名。

请有人帮我解决这个问题。

创建包含您发布的数据的对象。像这样：
public class MyData {
private String ticket;
private long saleID;
// ...
private List<MyProduct> products;
// constructor, getters and setters...
}
public class MyProduct {
private int menuItemId;
private int qty;
// ...
}
当您收到上面的JSON-Data-String时，您可以在GSON的帮助下将数据解析到您的对象中：
import com.google.gson.Gson;
final String jsonDataString = receive();
final MyData myData = new Gson().fromJson(jsonDataString, MyData.class);
当您在对象中收集数据并希望发送JSON-Data-String时，您也可以使用GSON：
final MyData myData = collectData();
final String jsonDataString = new Gson().toJson(myData);
send(jsonDataString);

我建议你创建一个setter和getter类，它具有与上面提到的json字符串相同的变量名。还要在该类中使用关联（继承）。在json内容中，在每个开始和结束花括号下，所有值都类似于java类的字段。
创建整个setter和getter类后，使用setter为每个变量设置值。然后创建一个像JSONObject类的Object。
public class JsonSimpleExample {
public static void main(String[] args) {
JSONObject obj = new JSONObject();
obj.put("name", "Sample");
obj.put("age", new Integer(100));
JSONArray list = new JSONArray();
list.add("msg 1");
list.add("msg 2");
list.add("msg 3");
obj.put("messages", list);
try {
FileWriter file = new FileWriter("c:\\test.json");
file.write(obj.toJSONString());
file.flush();
file.close();
} catch (IOException e) {
e.printStackTrace();
}
System.out.print(obj);
}
}
