// Create a cookie

public void setCookie(HttpServletResponse res,String value){

    Cookie cookie = new Cookie("Cookies I want to create ID", value); // 

Create a cookie by naming it( key, value )

    cookie.setMaxAge(60*60*24); // Cookie expiration date: set to one day(60seconds * 60minute * 24

hour)

    cookie.setPath("/"); // Make it accessible from all paths

    res.addCookie(cookie); //response에 Cookie add

}

​// Get Cookies

public String getCookie(HttpServletRequest req){

    Cookie[] cookies=req.getCookies(); // Get all cookies

    if(cookies!=null){

        for (Cookie c : cookies) {

            String name = c.getName(); // Get cookie name

            String value = c.getValue(); // Get cookie value

            if (name.equals("Cookies I'm Looking For ID")) {

                return value;

            }

        }

    }

    return null;

}

​// Remove specific cookies

public void deleteCookie(HttpServletResponse res){

    Cookie cookie = new Cookie("Cookies you want to delete ID", null); // Set the value for the cookie to be deleted to null

    cookie.setMaxAge(0); // Set the valid time to 0 to expire immediately.

    res.addCookie(cookie); // Add to response to make it go away

}

​

// remove all cookies

public void deleteAllCookies(HttpServletRequest req,HttpServletResponse res) {

    Cookie[] cookies = req.getCookies(); // Store information of all cookies in cookies

    if (cookies != null) { // Execute if there is at least one cookie

        for (int i = 0; i < cookies.length; i++) {

            cookies[i].setMaxAge(0); // set valid time to 0

            res.addCookie(cookies[i]); // Add to response to expire.

        }

    }

}
