Question

I need to call public methods of the rubberStampService from inside the RubberStampServiceImpl class.

To reference the rubberStampService from inside itself, can I make a self-referential bean declaration like this:

<beans:bean id="rubberStampService" class="com.rubberly.RubberStampServiceImpl">
    <beans:property name="rubberStampService" ref="rubberStampService" />
</beans:bean>

Sounds like an infinitely recursive, out of memory error waiting to happen. Why not just have the service call its own method and be done with it? You don’t need a new reference, just “this”.

public interface FooService()
{
    void foo();
    void bar();
}

public class FooServiceImpl implements FooService
{
    public void foo() { System.out.println("calling foo"); }
    public void bar()
    {
        this.foo(); // just call your own method.
    }
}
