Allow annotated methods on a Controller to be marked as exception handlers [SPR-4677]

[spring-projects-issues]

Kenny MacLeod opened SPR-4677 and commented

In some cases, I would like to be able to more tightly bind a controller's exception handling to the controller itself. I am imagining an @ExceptionHandler annotation which can be added to a controller's methods, which would be invoked by the framework if the @RequestMapping-annotated handler methods throw an exception. These annotated methods would be used in preference to the context-wide ExceptionResolvers.

This would be particularly useful in controllers with multiple @RequestMapping methods, all of which have related exception handling requirements, but which are specific to the controller. Handling this sort of complex exception handling logic in a context-wide ExceptionResolver is decoupling things too much from the source of the exceptions.

Thoughts?

We plan some general enhancements around annotated controllers in Spring 3.0, so I'm scheduling this for 3.0 M2.
