Can a Spring MVC controller return both a HttpServletResponse and a view?

My existing code is like:

String myController(@PathVariable someId, ModelMap map){
....
return "myViewName";
}

Now I want to set a cookie in some cases, so I need to get hold of a HttpServletResponse obj. Can I just add such a response obj to the list of params and operate on it in the controller? If so, I wonder how my own response is kind of reconciled with the response generated by the JSP that resolves the "myViewName".

Solution

  • Yes.

    @RequestMapping
public String myController(@PathVariable someId, ModelMap map, HttpServletResponse response) {
    // Do what you need to do on the response, like set a cookie
    return "myViewName";
}
