如何将java继承与 lombok 与 final （不可变数据类型）和 Gson ?

@ToString
@Getter
@EqualsAndHashCode(callSuper = false)
public abstract class AbstractContext {
  protected final String applicationUuid;
  protected final String userUuid;
  protected final String accountUuid;

  public AbstractContext(
      String applicationUuid, String userUuid, String accountUuid) {
    this.applicationUuid = applicationUuid;
    this.accountUuid = accountUuid;
    this.userUuid = userUuid;
  }

@ToString
@Getter
@EqualsAndHashCode(callSuper = true)
public class ChildContext extends AbstractContext {
  private final String foobar;

  public ChildContext(
      String applicationUuid, String userUuid, String accountUuid, String foobar) {
    super(applicationUuid, userUuid, accountUuid);
    this.foobar = foobar;
  }
}

Gson gson = new Gson();
ChildContext inputB =
        gson.fromJson(
            "{\"application_uuid\":\"deadbeef\",\"user_uuid\":\"aaabbb_4958\",\"foobar\":\"abc\"}",
            ChildContext.class);

但是，我得到的结果是其他父类字段为空

foobar=abc, application_uuid=null, user_uuid=null, account_uuid=null

我试着从 lombok ，但仍然是相同的结果
