spring-mvc when to use @CookieValue

Question

In a controller when should you use @CookieValue ?
Only when you know that you are sure that the cookie will be present ?

I have this controller:

@Controller
@RequestMapping("my")
public class MyController {


    @RequestMapping("")
    public ModelAndView index(@CookieValue("myCookie") String cookie,
                        Map<String, Object> model){

     log.info("My cookie {}", cookie);

     (...)
}

When the cookie is set, no problem the method is called, but when the cookie is not set the method is not called and I think I can not have another method in my controller mapped to the same path.

(my version of Spring: 3.2.3)

Answer 1

Answered by Kal in the comment,I put the answer to mark the question as answered/closed.

@CookieValue has a required parameter which is set on true by default.

So,

@CookieValue(value="myCookie", required=false)

solved my problem.

I suppose you also can use attribute "defaultValue". It's look like:

@CookieValue(value="name", defaultValue="someValue")
