Getting Id of a child object-attribute of a BeanPropertySqlParameterSource

I have a Question Bean:

public class Question implements IHaveId, IAuditable {

private long id;
private QuestionType questionType;
private String questionText;
private String questionHint;
private RenderMode renderMode;

...
Normal Bean getters and setters here
...

}

and another Answer Bean, note the two extra getters and setters for the Question Attribute : getQuestionId and setQuestionId

public class Answer implements IHaveId, IAuditable {

    private long id; 
    private String answerValue;
    private DataType dataType = DataType.UNKNOWN;
    private Question question;

  ...
  javabean getters and setters here 
  ...

  //Kindly note these extra two getters and setters
  public Long getQuestionId() {

        return question == null ? null : question.getId();
    }

    public void setQuestionId(Long questionId) {
        if(questionId == null)return;
        question = new Question();
        question.setId(questionId);
    }
}

I am using the Answer Bean as a BeanPropertySqlParameterSource when calling a Stored procedure using SimpleJdbcCall.

Map m = pspCreate.execute(in) = new BeanPropertySqlParameterSource(answer);

The parameters of the Stored procedure are the primitive type properties of the Answer Object with the id of the Object type properties.

For instance if a have a question_id parameter, JavaBean Reflection uses getQuestionId

How do I avoid this avoid adding the getQuestionId because it kind of duplicates the question Attribute?
