I have a quick comment and a question. First, the question: Will there be a way of configuring factory beans using annotations, or is there a way of doing so already that I am simply too dense to realize? As I understand it, currently the only way to specify a factory method is through the XML configuration. Now, the comment: I was surprised to read about your thought process in determining whether or not to include a way of configuring a bean's scope via an annotation. Certainly, the argument that a bean's scope should be a deployment-level configuration item is valid. However, most of us using Spring in our day-to-day development are constantly striking a balance between doing the "right" thing and doing the rapid thing. While a scope annotation breaches the separation of deployment description from bean description, in many cases a bean will only ever live in one scope, and there is a considerable benefit in convenience gained from having all of a bean's configuration specified right there in the source. Additionally, the Spring developers, it seems to me, have always championed choice and flexibility over proscription and rigidity, so I was very glad to see the introduction of the @Scope annotation. Thanks for providing such a valuable framework. Spring rocks, and your continued dedication to flexibility will make Spring 2.1 rock even harder!
