Lombok @SuperBuilder example with json annotations

Sebastian Thees :

can someone please provide me a working example with the lombok @SuperBuilder experimental annotation?

I can't get it running and there is no code example as documentation available.

Currently my code looks like this:

Superclass:

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.EXISTING_PROPERTY, property = "type")
@JsonSubTypes({
  @JsonSubTypes.Type(value = SubA.class),
  @JsonSubTypes.Type(value = AnotherSub.class)
})
@Getter
@Accessors(fluent = true, chain = true)
@SuperBuilder
public abstract class AbstractA {

    @JsonProperty
    protected final String superProperty;
}

And the subclass:

@Getter
@EqualsAndHashCode(callSuper = true)
@Accessors(fluent = true, chain = true)
@SuperBuilder
@JsonDeserialize(builder = SubA.SubABuilder.class) // class not found?
@JsonTypeName("SubA")
public class SubA extends AbstractA {

    @JsonProperty
    private final String fieldA;
}

Thanks

A working solution in Eclipse, note that the Lombok IntelliJ integration is not supporting all features, therefore the code compiles fine in Eclipse and with javac but IntelliJ thinks it's broken but executes the code without an issue.

public static ObjectMapper createObjectMapper() {

    final ObjectMapper mapper = new ObjectMapper();
    mapper.setAnnotationIntrospector(new JacksonAnnotationIntrospector() {

        @Override
        public JsonPOJOBuilder.Value findPOJOBuilderConfig(final AnnotatedClass ac) {
            if (ac.hasAnnotation(JsonPOJOBuilder.class)) {
                return super.findPOJOBuilderConfig(ac);
            }
            return new JsonPOJOBuilder.Value("build", "");
        }
    });

    return mapper;
}

public static void main(final String[] args) throws Exception {
    final ObjectMapper objectMapper = createObjectMapper();

    final String serializedForm = objectMapper.writeValueAsString(SubA.builder().build());
    System.out.println(serializedForm);
    final SubA anA = objectMapper.readValue(serializedForm, SubA.class);
    System.out.println(anA);
}


@Getter
@EqualsAndHashCode(callSuper = true)
@Accessors(fluent = true, chain = true)
@SuperBuilder
@JsonDeserialize(builder = SubA.SubABuilderImpl.class)
@JsonTypeName("SubA")
public static class SubA extends AbstractA {

    @JsonProperty
    private final String fieldA;
}


@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, property = "type")
@JsonSubTypes({
    @JsonSubTypes.Type(value = SubA.class)
})
@Getter
@Accessors(fluent = true, chain = true)
@SuperBuilder
public static abstract class AbstractA {

    @JsonProperty
    protected final String superProperty;
}
