How can I inject a bean into an ApplicationContext before it loads from a file?

Question

I have a FileSystemXmlApplicationContext and I would like the beans defined in the XML to take as a constructor argument a bean which is not declared in Spring

Answer 1

As I had trouble solving this with an AnnotationConfigApplicationContext, I found the following alternative:

DefaultListableBeanFactory beanFactory = new DefaultListableBeanFactory();
beanFactory.registerSingleton("customBean", new CustomBean());
context = new AnnotationConfigApplicationContext(beanFactory);
context.register(ContextConfiguration.class);
context.refresh();
