ProGuard可以使子类的字段名称与超类不同

Question

Suppose I have these classes:

public class Superclass {
    private int intValue;
}

public class Subclass extends Superclass {
    private String stringValue;
}

ProGuard may obfuscate them to be:

public class A {
    private int a;
}

public class B extends A {
    private String a;
}

Can I make Ba become another name not exists in its superclass, eg Bb ? My classes are about to be used in serialization (JSON), stored locally so that I don't need the original field name, just need them to be different.

Answer 1

As far as I know, you should keep the classes used in serialization. Processing serializable classes suggests that you should write something like:

 -keepclassmembers class * implements java.io.Serializable { 
 private static final java.io.ObjectStreamField[] serialPersistentFields; 
 private void writeObject(java.io.ObjectOutputStream); 
 private void readObject(java.io.ObjectInputStream); 
 java.lang.Object writeReplace(); 
 java.lang.Object readResolve(); 
}
