使用Gson如何将变量名称添加为REST调用的json的顶级参数(Using Gson how to add variable name as top level parameter for json of a REST call)

 我正在尝试调用REST服务并使用gson我得到以下java pojo的以下json。 
 
 POJO 
 
public class AlphaParameters {
private  int one;
private int two;
private int three;

//getter setters
//constructors
}
 
 JSON 
 
{"one":4,
"two":5,
"three":10
}
 
 我使用以下代码 
 
Gson gson = new Gson()
AlphaParameters alphaParameters = new AlphaParameters(one,two,three);
gson.toJson(alphaParameters );
 
 之前这段代码曾经工作过，但现在看来.net上的服务器端改变了它们的实现，现在他们期望以下格式的json。 一切都是一样的，但现在看来他们想要在json中使用顶级变量名。 
 
{"alphaParameters":
    {"one":4,
    "two":5,
    "three":10
    }
}
 
 问题 ：是否有一个特定的Gson API，我可以使用它来生成上面的json而不重构我的代码？ 或者编写包装类以包含alphaParameters将是一种更好的方法。 （我将不得不为后者编写很多样板代码）。 
 
 谢谢你的帮助。 

I am trying call a REST service and using gson I am getting the following json for the following java pojo.
 
pojo
 
public class AlphaParameters {
private  int one;
private int two;
private int three;

//getter setters
//constructors
}
 
Json
 
{"one":4,
"two":5,
"three":10
}
 
I am using the following code
 
Gson gson = new Gson()
AlphaParameters alphaParameters = new AlphaParameters(one,two,three);
gson.toJson(alphaParameters );
 
Earlier this code used to work, but now seems the server side which is on .net changed their implementation and now they are expecting the json in the following format. Everything is same but seems now they want the toplevel variable name in the json.
 
{"alphaParameters":
    {"one":4,
    "two":5,
    "three":10
    }
}
 
Question : Is there a specific api of Gson which I can use to generate the above json without refactoring my code ? Or writing a wrapper class to include alphaParameters will be a better approach . ( I will have to write a lot of boilerplate code for latter ).
 
Thanks for your help.
