Spring MVC Controller configuration - mixing annotations and XML @PathVariable

I am developing a web app using the Spring MVC framework (v3).

Currently I have several controller classes defined - I have created them by extending the MultiActionController and then in my web mvc XML config defined the beans and the URL mappings:

QuestionController.java:

public class QuestionController extends MultiActionController implements InitializingBean 
{

webmvc-config.XML

<bean id="questionController" class="com.tmm.enterprise.microblog.controller.QuestionController"></bean>
...
    <bean id="fullHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="alwaysUseFullPath开发者_如何学Go" value="true" />
        <property name="mappings">
            <props>
                <prop key="/question/**">questionController</prop>
            </props>
        </property>
    </bean>  

This works fine, I define methods in my controller matching the URLs being called and everything works correctly (for example, I have a list(..) method, that gets correctly executed when I browse to /question/list).

However, for this particular controller I want to make use of the @PathVariable option in Spring to allow for variable URLs (e.g. i want a details(..) method, that when I call /question/detail/9999 - where 9999 is a question ID the method is executed). I have tried to use this as follows:

QuestionController.java:

@RequestMapping("/detail/{questionId}")
public ModelAndView detail(@PathVariable("questionId") long questionId, HttpServletRequest request, HttpServletResponse response) throws Exception{

However, I get an error when I run the above and get:

Could not find @PathVariable [questionId] in @RequestMapping

Has anyone come across this before? Is it ok to mix RequestMapping annotations with the existing XML configured URL mapping?

This is the comment from DefaultAnnotationHandlerMapping class, If i am reading the comment right, If you add @RequestMapping at the top of your QuestionController.java, It might resolve your problem

Annotated controllers are usually marked with the {@link Controller} stereotype at the type level. This is not strictly necessary when {@link RequestMapping} is applied at the type level (since such a handler usually implements the {@link org.springframework.web.servlet.mvc.Controller} interface). However, {@link Controller} is required for detecting {@link RequestMapping} annotations at the method level if {@link RequestMapping} is not present at the type level.

EDIT

You can do some thing like this, move the /question part of the uri to the top and leave the detail part at the method level

@RequestMapping("/question")
public class QuestionController
{
  @RequestMapping("/detail/{questionId}")
  public ModelAndView detail(@PathVariable("questionId") long questionId,    HttpServletRequest request, HttpServletResponse response) throws Exception{

}
