Please STOP asking the same question over and over again!

Sorry, Stephan, I think Spring probably knows better than to doubly-define beans within its own factory. But the Bean Factory for JSF and the Bean Factory are two separate factories, both tied by the JSF/Spring bridge, so they're less likely to be understanding.

How do you override a bean in a spring boot?

Bean Overriding Spring beans are identified by their names within an ApplicationContext. Thus, bean overriding is a default behavior that happens when we define a bean within an ApplicationContext which has the same name as another bean. It works by simply replacing the former bean in case of a name conflict.

Can we define two beans with same name in spring?

Can I define spring bean twice with same name in different bean definition file? Yes. When the second bean definition file loads, it overrides the definition from the first file. The main objective of this behavior is to ovrrride the previously loaded bean definition.

Can we have 2 beans with same name?

There is no solution for same bean name. At run-time when you will get the autowired class then the primary true bean will get the preference for autowiring.
