Question

I have one abstract class and two implementations. Let’s call them ParentAbstract, ParentA and ParentB. ParentAbstract has a property of type BeanAbstract: bean. There are two implementations of this abstract class: BeanA and BeanB.

Is is possible to use Spring so that it will inject BeanA in ParentA and BeanB in ParentB?

Note that I cannot use ParentA and ParentB as Spring beans because they are Wicket pages.

Answer 1

In your ParentAbstract add an abstract method

abstract setBean(BeanAbstract bean);

Then in the subclasses, overrride them and annotate:

@Override
@Autowired
@Qualifier("name") // or @Resource("name")
setBean(BeanAbstract bean) {
    this.bean=bean;
}
