接口的使用达到了即用即设的效果，zhuanghua（）方法是一个底层方法，本人认为可以存放在，模型包中设为包级访问权限。功能：实现了通用的在规定的映射关系下，将两个模型互相转换。

zhuanhuaObject方法的功能：定义模型转化的映射关系，可将任何其他类型的模型转化为this对象，实现时机：在你需要将任意一个模型转化为本模型时可将此方法的实现写在改模型类中，并且实现映射关系zhuanhuaList方法的功能：定义模型转化的映射关系，可将两个给定的list类型的数据集合转换，实现时机：在你需要将任意一个模型转化为本模型时可将此方法的实现写在改模型类中，并且实现映射关系 zhuanhuaList的完善：达到可将任何其他类型的list集合数据转化为某对象的lit集合。
