Spring MVC Interceptor Documentation [SPR-5158]

[spring-projects-issues]

Stephen M. Wick opened SPR-5158 and commented

When I read section 13.4.3 "Intercepting requests - the HandlerInterceptor interface", I am left wondering, "Do the interceptors specified in the handler mapping bean get invoked for every request handled by the DisplatcherServlet, or do they just get invoked when a request matches one of the URL patterns specified in the mappings property of the handler mapping bean?"

I think it would be a good idea to answer this question in the Spring reference document under section 13.4.3.

Thanks! And, Great work! The Spring Framework project has been so helpful!

Stephen

This seems more a lack of understanding of the handler mapping itself. The doc seems reasonably clear that the interceptor is part of the handler mapping, and hence is only applied to requests which are handled by that mapping. However, I've expanded the text a bit to spell this out, particularly w.r.t. the sample code.
