Restful Path Parameters in Spring MVC 3

Question

Is it possible to: set a URI template in the mvc:view-controller element of the *-servlet.xml file or in a controller method and then use/get that path parameter in a js

Answer 1

The Map of resolved path variables is exposed as an attirubte with name specifed by HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE. So, the solution is

<c:if test="${not empty requestScope['org.springframework.web.servlet.HandlerMapping.uriTemplateVariables']['error']}">

But accessing it this way is probably not a best idea, Affe's solution is cleaner.

Answer 2

If you want access to it in the jsp, return it as an attribute from the controller:

@RequestMapping("/home/{error}")
public void handleError(@PathVariable String error, ModelMap model) {
    //your regular stuff

    model.addAttribute("error", error);
}

-

<c:if test="${not empty error}">
<span class="error">You have an error...</span>
</c:if>
