In Restlet 1.2, SpringBeanRouter has been updated to pass the application context to the finders it creates, if an application context is available. It makes sense to use the same mechanism for SpringBeanFinder directly. New issue: http://restlet.tigris.org/issues/show_bug.cgi?id=751 > 2.

My suggestion would be to use SpringBeanRouter if you want Spring- managed resource beans, unless you need to map multiple routes to the same resource. A static map with refs (such as that used by SpringRouter) wouldn't work for spring-managed resources, since they need to be non-singletons. You could write your own map-based router that uses ApplicationContextAware (as you suggest) and attaches SpringBeanFinders for each bean name / URL pattern pattern pair. I don't think that modifying SpringRouter to achieve this is the right way to go -- it would make SpringRouter complex and branching in a way that isn't justified by the amount of code that would be shared between the variants. If you do write your own router, I'm sure Jerome would be willing to consider adding it to the spring extension. > Well sorry for lot of text probabaly not well written :) > Will be appreciate for any response. > > Maybe i havent found related open issues in issue tracking > or in case you need any help on better spring integration or idea i > will > be glad to help Rhett ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=1263762
