扩展可序列化的类时的警告

Question

I have a class A implementing Serializable and another class B extends A , but I want to use class B for XML binding, not for serialization.

Is there anything I should worry about?

Answer 1

Assuming you've implemented all of the Serializable methods in A , nope. You won't need to worry about implementing them, since that's already done. If there are any naming conflicts between XML binding and serialization, you can define the method in B and your XML binding library will call the methods for B , not those of A (ie polymorphism ).

The only potential worry is a method that takes an argument of type Serializable -- if B , for whatever reason, shouldn't be (de)serialized, this is a problem. I doubt that this is a problem for you, if only because there are so few cases when it would apply.
