REST异常需要构造函数

我有一个休息的Web服务，它返回一个 FoodItem 类的对象，它没有't have public empty constructor. However, It contains another constructors which aren't空参数 .

我得到了这个例外

当我在 FoodItem 类中创建公共空参数构造函数时，异常解决了，我得到了确切的结果 .

My question: 如何在不添加空构造函数的情况下解决该异常？在我的业务逻辑中不可能有空构造函数 .

提前致谢

Edit 我的类实现了一个接口，也许这些信息可以帮到你 .

Edit2 如果你想要我的 web.xml ，我的课程，我的界面或我的网络服务的代码，我准备好了

Edit3

这是Web服务中的代码

@GET
    @Produces(MediaType.TEXT_XML)
    public FoodItem getRestarantsFordBrowser() {
        return FoodItemImpl.getInstance(1);
    }

如你所见，我正在调用静态方法 .

静态方法的代码是：

public static FoodItem getInstance(int ID) {
        return new FoodItemImpl(ID);
    }

and this constructor is PRIVATE, so I don't need a public constructor to create objects and in my web service I am calling method static so I don't have to create object explicity.
