How to override @JsonProperty(value = "id", access = JsonProperty.Access.READ_ONLY) on object mapper

I've a model class which I can't change its source, it is annotated with

public class Announce {

   @JsonProperty(value = "id", access = JsonProperty.Access.READ_ONLY)
   @Id
   @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "announce_sequence")
   @SequenceGenerator(name = "announce_sequence", sequenceName = "announce_id_sequence", allocationSize = 100)
   @Setter(AccessLevel.NONE)
   private Long id;
}

Due that access = JsonProperty.Access.READ_ONLY ObjectMapper won't deserialize the id that comes in the json response I get.

Is there a way to force it ignore JUST THAT ANNOTATION [override it]?

my status:

• I cant change original pojo
• I cant .disable(MapperFeature.USE_ANNOTATIONS) because this pojo is long and complex and the annotations are necessary for many other properties [46 properties in total]
• I really wouldn't like to write a whole new DTO
• I've been trying to use mixIn to override such annotation but either i'm doing something wrong or it doesn't work
• I thought about writing a custom deserializer and manually setting that specific field, but couldn't find a way to get the default deserializer to deserialize the whole object and give me just the missing property

Does anyone have any idea what I can do?

anyone with real experience with mixIn can tell me they should work?

I'm still hopping someone can teach me how to do that with mixIns or some small tweaks in the ObjectMapper configurations but I'm posting my current solution so other people can have an idea

@Configuration
public class ObjectMapperConfiguration {
   @SneakyThrows
   @Autowired
   public void configureObjectMapper(@NonNull final ObjectMapper objectMapper) {
      objectMapper.registerModule(new SimpleModule().addDeserializer(Announce.class, new JsonDeserializer<Announce>() {
         private final Field field = Announce.class.getDeclaredField("id");

         @Override
         public Announce deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JacksonException {
            final InnerAnnounce result = objectMapper.readValue(p, InnerAnnounce.class);
            ReflectionUtils.setField(field, result, result.innerId);
            return result;
         }
      }));
   }


   @Setter
   private static final class InnerAnnounce extends Announce {
      @JsonAlias({"id"})
      private Long innerId;
   }
}

The origial ObjectMapper bean is crated in another class so i get it, add a new deserializer that will deserialize into a child class, which was custom made to have the minimum possible modifications, and later I set the extra field by reflection

It is a really small workaround but I not a fan of using reflection in my own code like this
