序列化字段类别

Question

I need to pass java.lang.reflect.Field from one process to another using RMI, but Field does not implement Serializable interface. how can I overcome this problem?

Answer 1

It doesn't make sense to pass a Field via RMI. A Field instance is really a dependent object of a java.lang.Class instance, and Class objects are not transmissible either. (And the reason that a Class is not transmissible is that it would present all sorts of nasty type checking problems ... considering that a Class instance actually denotes a reference type.)

You will need to declare the relevant Field field as transient . If you want to transmit the Field information, you are probably going to need to pass it in the form of a field name / class name, and then reconstruct the Field at the other end in a custom readObject method.
