Question

I’m trying ot write an integration test for one of my methods, that handles a form submission.
The problem is that i use @PathVariable int id in the @RequestMapping of my controller.
I get the following error message when my test method reaches the .handle() part.

nested exception is java.lang.IllegalStateException: Could not find @PathVariable [id] in @RequestMapping

So the controller cant reach the id. I’m using request.setRequestURI("/url-" + s.getId()); But appareantly its not helping with setting up @PathVariable.
Is there any way to set up the @PathVariable of my Mock object?

Update:

Yeah, im useing MockHttpServletRequest and annotationMethodHandlerAdapter.handle in my test class.

The Controller:

@RequestMapping(method = RequestMethod.POST, params = {"edit" })    
public String onSubmit(@ModelAttribute("sceneryEditForm") SceneryEditForm s,
            @PathVariable int id, Model model) {
       // some code that useing id
}

The test method:

@Test
public void testEditButton() throws Exception {
        MyObject s = new MyObject();
        request.setMethod("POST");
        request.setRequestURI("/edit-" + s.getId());
        request.setParameter("edit", "set");
        final ModelAndView mav = new AnnotationMethodHandlerAdapter()
                                       .handle(request, response, controller);  
        assertViewName(mav, "redirect:/view-" + s.getId()); 
    }

The error is correct: there is no path variable id

You need to add the path expression with an placeholder id

@RequestMapping(value = "/something/{id}",
                method = RequestMethod.POST,
                params = {"edit" })
public String onSubmit(@ModelAttribute("sceneryEditForm") SceneryEditForm s,
        @PathVariable int id, Model model) {
   // some code that useing id
}
