Answer 1

to do this you need to have a application-context.xml in place under the META-INF folder, apart from this you need to define your beans in xml file using tag, you need to inject your dependency in beans using either constructor injection or setter injection. and then you can use these beans.

I would suggest you to keep it annotation based its more readability while using annotation, You can find xml based configuration here in this example

XML Based Controller Configuration further more refer to spring documentation. Also you need to include these configuration file in your web.xml as well.
