Я пытаюсь десериализация «OnClick» события, содержащееся в «модуле» объект, представленный следующей JSON:десериализация родительского объекта на основе идентификатора
{
"parent": {
"id": 0,
"children": [{
"child": {
"id": 1,
"description": "A",
"parent": 0,
"events": [{
"onclick": {
"source": 1
}
}]
}
}]
}
}
Классовая структура очень проста:
View (Interface)
+- AbstractView
+- Parent
+- Child
Event (Interface)
+- AbstractEvent
+- OnClick
AbstractEvent:
public abstract class AbstractEvent implements Event {
private View source;
protected AbstractEvent() {}
protected AbstractEvent(View source) {
this.source = source;
}
@Override
public View getSource() {
return source;
}
@Override
public void setSource(View source) {
this.source = source;
}
}
Я использую Примеси, как модель используется betwee n несколько различных проектов.
ViewMixIn:
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT, property = "type")
@JsonSubTypes({
@Type(value = Parent.class, name = "parent"),
@Type(value = Child.class, name = "child")
})
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public abstract class ViewMixIn {
}
EventMixIn:
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT, property = "class")
@JsonSubTypes({
@Type(value = OnClick.class, name = "onclick")
})
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "source")
public abstract class EventMixIn {
}
SimplifiedModule:
@Override
public void setupModule(SetupContext context) {
super.setupModule(context);
context.setMixInAnnotations(AbstractView.class, ViewMixIn.class);
context.setMixInAnnotations(AbstractEvent.class, EventMixIn.class);
}
конфигурации ObjectMapper:
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new SimplifiedModule())
.setSerializationInclusion(NON_NULL)
.setSerializationInclusion(NON_EMPTY)
.enableDefaultTyping()
.enableDefaultTyping(NON_FINAL, As.WRAPPER_OBJECT)
.setVisibilityChecker(
mapper.getSerializationConfig().getDefaultVisibilityChecker()
.withFieldVisibility(JsonAutoDetect.Visibility.ANY)
.withGetterVisibility(JsonAutoDetect.Visibility.NONE)
.withSetterVisibility(JsonAutoDetect.Visibility.NONE)
.withCreatorVisibility(JsonAutoDetect.Visibility.NONE));
Как видно, модель сериализация правильно, но при десериализации я получаю следующее сообщение об ошибке:
WARN 11:46:04:949 br.com.pdcore.appmaker.middleware.simplified.SimplifiedModelTest - Could not deserialise Parent. com.fasterxml.jackson.databind.JsonMappingException: Unexpected token (VALUE_NUMBER_INT), expected START_OBJECT: need JSON Object to contain As.WRAPPER_OBJECT type information for class br.com.pdcore.appmaker.middleware.simplified.model.view.View at [Source: {"parent":{"id":0,"children":{"java.util.ArrayList":[{"child":{"id":1,"description":"A","parent":0,"events":{"java.util.ArrayList":[{"onclick":{"source":1}}]}}},{"child":{"id":2,"description":"B","parent":0,"events":{"java.util.ArrayList":[{"onclick":{"source":2}}]}}},{"child":{"id":3,"description":"C","parent":0,"events":{"java.util.ArrayList":[{"onclick":{"source":3}}]}}},{"child":{"id":4,"description":"D","parent":0,"events":{"java.util.ArrayList":[{"onclick":{"source":4}}]}}},{"child":{"id":5,"description":"E","parent":0,"events":{"java.util.ArrayList":[{"onclick":{"source":5}}]}}}]}}}; line: 1, column: 145] (through reference chain: br.com.pdcore.appmaker.middleware.simplified.model.view.Parent["children"]->java.util.ArrayList[0]->br.com.pdcore.appmaker.middleware.simplified.model.view.Child["events"]->java.util.ArrayList[0]->br.com.pdcore.appmaker.middleware.simplified.model.event.OnClick["source"])
Как будто не понимая, что «источник» идентификатор относится к дочернему объекту оберточного узла OnClick.
Если я изменяю Смешение определений из:
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.WRAPPER_OBJECT, property = "name")
к:
@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "type")
Я все еще получаю подобную ошибку:
