Question

Suppose have following beach definition:

<bean id="singletonBean" class="...">
   <property name="instanceBean" ref="instanceBean"/>
</bean>

<bean id="instanceBean" class="..." scope="prototype"/>

When I call:

singletonBean = context.getBean("singletonBean");

...some code...

singletonBean = context.getBean("singletonBean");

Would property instanceBean of singletonBean be initialized again or it would just use already created singleton?

Answer 1

Would just use already created singleton.

A prototyped inner bean of a singleton won’t be recreated each time you get the singleton from context. The singleton and all is references are created one for all.

But context.getBean("instanceBean"); would give you a new since scope is ‘prototype’.
