What does mappedInterceptors do in SimpleUrlHandlerMapping

Question

I have an application running on SpringFramework version 3.0, it uses SimpleUrlHandlerMapping bean to map the requests to controllers. It has the following properties set [ order, mappings, interceptors, mappedInterceptors ].

I understand that interceptors can be used for pre/post handling of the requests. But i dont understand the purpose of mappedInterceptors. I could not find any documentation explaining this. The Spring-3.0.x doc doesnt explain on this either (http://tinyurl.com/kcuwp8h ). SimpleUrlHandlerMapping in Spring 3.1 doesnt even have this property.

Can someone pls tell me what is it used for? and How is it achieved in Spring 3.1 ? Thanks.

Answer 1

In Spring 3.1 SimpleUrlHandlerMapping inherits the property from AbstractHandlerMapping.

MappedInterceptor is just a wrapper for HandlerInterceptor and can be used to restrict the execution of an interceptor to a certain request path.

I don't know if Spring currently uses this feature at all. The source code does not show any usage. That would explain the lack of documentation.
