Answer 1

You can perform DI on any instance, whether Spring managed or created with new.

To do so, use the following code...

AutowireCapableBeanFactory awcbf = applicationContext.getAutowireCapableBeanFactory();
awcbf.autowireBean(yourInstanceCreatedWithNew);

This is also a great way to introduce Spring into an application that was developed originally without Spring - as it allows you to use Spring where you want it without having to convert every class in the application into a Spring bean (because typically, you can't use a Spring bean without a Spring bean).
