How to make an objects implements Serializable through Reflection dynamically?

I have to add implements Serializable dynamically in an object(different classes as Object) to as Spring requires some functionality. I found workarounds but it does not fit because the adapter pattern is not compatible with with "dynamically" term. I found Proxy.newProxyInstance() but it creates only a new instance of interface or class and doesn't make a class implement an interface. And I didn't find any methods that I might use in getClass()

Do you know how to do this?
