RequestMapping not working with multi-level URLs - spring

Question

I have a scenario where I'm making a simple get request through a link and my #RequestMapping configuration is not behaving as I'd expect.
Within an anchor tag I reference a url with the following pattern '/action-plan/export/pdf?token=xxx&taskId=1111&taskId=2222...'
Within my controller class I have this mapping at the class level:
#RequestMapping("/action-plan/export")
And this mapping at the method level
#RequestMapping(value="/pdf", method=RequestMethod.GET)
public String exportToPdf(#RequestParam("taskId") String[] taskIds,
#RequestParam("token") String[] encryptedEmplId, ModelMap model)
But every time I try this I get a 404 page not found error and the following Spring exception:
org.springframework.web.servlet.mvc.multiaction.NoSuchRequestHandlingMethodException: No matching handler method found for servlet request: path '/pdf', method 'GET', parameters map['taskId' -> array['1962326', '1962264', '1962317', '1962328', '1962324', '1962427', '1962325', '1962323', '1963147', '1962327', '1962318', '1962329', '1962330'], 'token' -> array['xxxx']]
I've noticed that when I remove the "/pdf?" portion of the link and remove 'value="/pdf"' from the method #RequestMapping it works fine. For the life of me I don't understand why adding /pdf to the url and RequestMapping is not working.

Answer 1

I think danny.lesnik's answer was pretty close but I'm writing my own answer so I can be more verbose.
I was working on a different project and figured out why the above doesn't work. In reference to my original question here is the relevant web.xml servlet mapping:
<servlet-mapping>
<servlet-name>spring-dispatcherServlet</servlet-name>
<url-pattern>/action-plan/export/*</url-pattern>
</servlet-mapping>
I noticed that whatever portion of the path I included in the of web.xml was not being included in the evaluation of RequestMapping values. I would have thought this bean configuration would have prevented that scenario (note the "alwaysUseFullPath" property):
<bean id="annotationHandlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="order" value="2"/>
<property name="alwaysUseFullPath" value="true"/>
</bean>
Maybe someone can shed some light on this detail for me.
In any case, thanks danny.lesnik

I recreated your problem and solved it by mapping servlet using .action extentions.
For example:
#Controller
#RequestMapping(value="/test")
public class DefaultController {
#RequestMapping(value="/pdf.action", method=RequestMethod.GET)
public ModelAndView indexView(#RequestParam("taskId") String[] taskIds,
#RequestParam("token") String[] encryptedEmplId){
ModelAndView mv = new ModelAndView("index");
return mv;
}
Spring XML mapping:
<context:annotation-config />
<context:component-scan base-package="com.vanilla.controllers" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
and this web.xml servlet mapping
<display-name>SpringMvcServlet</display-name>
<servlet>
<servlet-name>SpringMvcServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringMvcServlet</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
This code resolves this url
/test/pdf.action?token=3&token=4&taskId=4
flawless.
