Defining the same Spring bean twice with same name

Question

Is having two definition for a bean (with same name and class) valid in Spring IOC ?

I am having two bean definition files included in web.xml. See the sample below.

Answer 1

From Spring Boot version 2.1 it is disabled by default. (link)

Bean Overriding: Bean overriding has been disabled by default to prevent a bean being accidentally overridden. If you are relying on overriding, you will need to set spring.main.allow-bean-definition-overriding to true.
