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
