Polymorphic Type Handling

[BenDol]

Is this different to using JsonTypeInfo?
I have this working for myself like so:

• Location -> DomainObject
• Site -> DomainObject
• Area -> DomainObject

@JsonTypeInfo( use = JsonTypeInfo.Id.CLASS )
public abstract class DomainObject implements Serializable, IsSerializable {

    public abstract int getId();

    public abstract void setId(int id);
}

So I can have the return type as DomainObject and it will be deserialized as whatever child object that is passed across the wire. Not 100% sure if this is what you are talking about here though.

 {
    "@class":"nz.co.doltech.ims.shared.domains.Location",
    "id":1,
    "name":"Mt Maunganui",
    "description":"Mt Maunganui description here!",
    "order":0,
    "removed":false,
    "sites":[

    ],
    "displayName":"Mt Maunganui",
    "orderValue":0
 }

As Ben said, @JsonTypeInfo is already supported.

Global default typing is not but you can achieve something almost similar by using mix in annotations and add @JsonTypeInfo directly to Object.

Nice. @JsonSubTypes is also supported? Like the pattern below:

@JsonTypeInfo(use=JsonTypeInfo.Id.NAME, include=JsonTypeInfo.As.PROPERTY, property="type")
@JsonSubTypes({
        @JsonSubTypes.Type(value=Dog.class, name="DOG"),
        @JsonSubTypes.Type(value=Cat.class, name="CAT"),
})
public interface Animal {
    ...
}
