@CookieValue and @RequestHeaders

No more extra code required to get the Cookie value and Header values in spring 3...

Spring 3 introduced below annotations to get the cookie values and header values

1) @CookieValue
2) @RequestHeader

@CookieValue : It allows a method parameter to be bound to the value of an HTTP cookie.

Example :
Let's assume the cookie (mycookie) has been received with an http request, below is the code to get the cookie in controller

  
@RequestMapping(value = "/success.do",method = RequestMethod.POST)
public String submitForm(@CookieValue("mycookie") String cookie)  {
 System.out.println("my cookie"+cookie);
 ....................
} 

If you want to set the cookie in Http response, then you can use below code

  
@RequestMapping(method = RequestMethod.GET)
 public String registrationForm(ModelMap model, HttpServletResponse response) {
  Cookie myCookie = new Cookie("myCookie", "val");
  response.addCookie(myCookie);
   ...................
 }
