Firebase java object serialization and Inheritance [duplicate]

问题

This question already has answers here:

How to deserialise a subclass in Firebase using getValue(Subclass.class) (4 answers)

Closed 3 years ago.

Does it also serialize inherited properties?

@IgnoreExtraProperties
public class Item extend BaseObservable {
    private String foo;

    public Item() { }

    @Bindable
    public String getFoo() {
        return this.foo;
    }
}

I just ran into the same issue and found your question. While I could not find a definitive answer elsewhere, some experimentation revealed that neither public fields nor getters are inherited.

Since my base class is abstract, I just made the fields protected and implemented getters to return them in each subclass. The repetition isn't ideal, but my objects are now saving in Firebase with the inherited fields.
