Spring 3 MVC accessing HttpRequest from controller

Question

I would like to handle request and session attributes myself rather then leave it to spring  SessionAttributes  for login of cookies handling for example    I just cant figure out how could I access the HttpRequest from within a controller  I need a way to go a layer above the  RequestAttribute and access the HttpRequest itself  With Stripes in used to do this by implementing an ApplicationContext and calling getAttribute     Also  passing the HttpServletRequest as parameter seems not to be working    RequestMapping value      public String home HttpServletRequest request       System out println    request getSession   getCreationTime         return  home        The above method does not print anything   Do you have any advice on this

Spring MVC will give you the HttpRequest if you just add it to your controller method signature   For instance          Generate a PDF report         RequestMapping value     report  objectId    method   RequestMethod GET  public  ResponseBody void generateReport           PathVariable  objectId   Long objectId           HttpServletRequest request           HttpServletResponse response                       Here you can use the request and response objects like         response setContentType  application pdf           response getOutputStream   write            As you see  simply adding the HttpServletRequest and HttpServletResponse objects to the signature makes Spring MVC to pass those objects to your controller method  You ll want the HttpSession object too   EDIT  It seems that HttpServletRequest Response are not working for some people under Spring 3  Try using Spring WebRequest WebResponse objects as Eduardo Zola pointed out   I strongly recommend you to have a look at the list of supported arguments that Spring MVC is able to auto-magically inject to your handler methods

I know that is a old question  but     You can also use this in your class    Autowired private HttpServletRequest context    And this will provide the current instance of HttpServletRequest for you use on your method
