Description

See the following test:

package org.apache.johnzon.jsonb.polymorphism;

import jakarta.json.bind.annotation.JsonbSubtype;
import jakarta.json.bind.annotation.JsonbTypeInfo;
import org.apache.johnzon.jsonb.test.JsonbRule;
import org.junit.Rule;
import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class JsonbNestedPolymorphismTest {
    @Rule public JsonbRule jsonb = new JsonbRule();

    @Test
    public void test()
    {
        Wrapper wrapper = new Wrapper();
        wrapper.something = new ConcreteSomething();

        assertEquals("{\"something\":{\"@type\":\"concrete\",\"value\":\"asdf\"}}", jsonb.toJson(wrapper));
    }

    @JsonbTypeInfo({
            @JsonbSubtype(alias = "concrete", type = ConcreteSomething.class)
    })
    public static class AbstractSomething {

    }

    public static class ConcreteSomething extends AbstractSomething {
        public String value = "asdf";
    }

    public static class Wrapper {
        public AbstractSomething something;
    }
}
 

 

Test result:

org.junit.ComparisonFailure: 
Expected :{"something":{"@type":"concrete","value":"asdf"}}
Actual   :{"something":{"value":"asdf"}}
