Question

I\'m trying to setup some code that will behave one way if spring\'s request scope is available, and another way if said scope is not available.

Answer 1

You can use the if check described here

SPRING - Get current scope

if (RequestContextHolder.getRequestAttributes() != null) 
    // request thread

instead of catching exceptions. Sometimes that looks like the simplest solution.

Answer 2

You can inject a Provider<MyRequestScopedBean> and catch the exception when calling the get method but you should rethink your design. If you feel strongly about it you should probably have two beans with different qualifier

Edit

On second thought, if you are using java configuration, @Scope("prototype") your @Bean method and make your decision there, you can get a handle on request context via RequestContextHolder if available. But I strongly recommend you rethink your design
