Spring mvc 3 : How to get path variable in an interceptor?

问题

In Spring MVC controller, I can get path variable using @PathVariable to get the value of a variable defined in @RequestMapping. How can I get the value of the variable in an interceptor?

Thank you very much!

回答1:

The thread linked to by Pao worked a treat for me

In the preHandle() method you can extract the various PathVariables by running the following code

Map pathVariables = (Map) request.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);

There is a thread in the Spring forums, where someone says, there is no "easy way", so i suppose you would have to parse the URL to get it.

Almost 1 year too late, but:

         String[] requestMappingParams = ((HandlerMethod)handler).getMethodAnnotation(RequestMapping.class).params()

         for (String value : requestMappingParams) {...

should help
