我能用jackson序列化基于外部键的子类吗？

public class ParentClass {
    private String id;
    private ChildClass child;

    // getters and setters
}

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.EXTERNAL_PROPERTY, property = "type")
@JsonSubTypes({
    @JsonSubTypes.Type(value = ChildClass1.class, name = "child1"),
    @JsonSubTypes.Type(value = ChildClass2.class, name = "child2")
})
public abstract class ChildClass {
    // common properties and methods
}

public class ChildClass1 extends ChildClass {
    // additional properties and methods specific to ChildClass1
}

public class ChildClass2 extends ChildClass {
    // additional properties and methods specific to ChildClass2
}

ObjectMapper mapper = new ObjectMapper();
String json = mapper.writeValueAsString(parentObject);

String json = "{\"id\":\"123\",\"type\":\"child1\",\"child\":{\"property\":\"value\"}}";
ParentClass parentObject = mapper.readValue(json, ParentClass.class);
