request scoped beans in spring testing

Question

I would like to make use of request scoped beans in my app. I use JUnit4 for testing. If I try to create one in a test like this:

@RunWith(SpringJUnit4Clas

NOT reading the docs sometimes drives one crazy. Almost.

If you are using shorter-lived beans (request scope for example), you most likely also need to change your lazy init default! Otherwise the WebAppContext will fail to load and tell you something about missing request scope, which is of course missing, because the context is still loading!

http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/beans.html#beans-factory-lazy-init

The Spring guys should definitely put that hint into their exception message...

If you don't want to change the default, there is also the annotation way: put "@Lazy(true)" after @Component etc. to make singletons initialize lazy and avoid instantiating request-scoped beans too early.
