根和子应用程序上下文中具有相同名称的Bean？

Question

If I create bean with same name in Root Application context and Child Application context
( as in Root Application Context and dispatcher servlet context )
will child application context override the bean definition ?
What will be the behavior please explain ?
Also explain what will be the behavior In Java Config if I include other Configuration Class and both contain bean with same name.
Will two beans be created ? Or one will override the other.

Answer 1

As per my Experimentation

In the parent and child Application Context new Bean is created for each Application Context irrespective whether Bean name is same or not .

Any call made from ( autowired by ) parent application context refers to Bean in Parent Application Context .
Any call made from ( autowired by ) child application context refers to Bean in Child Application Context .

And In Java Config importing other configuration which contains bean with same name does not create a new Bean and Bean Definition is Overridden. This effect is same as Importing bean of same name from XML.
