java中对cookie的简单处理

class

{

public ActionForward index(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response) {

Cookie[] cookies = request.getCookies();

if (null == request.getSession().getAttribute("userMsg")) {

if (cookies != null) {

boolean cookie = false;

String userName = "";

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

if (cookies[i].getName().equals("boyin")) {

userName = cookies[i].getValue();

cookie = true;

break;

}

}

if (cookie = true) {

//业务处理

}

}

}

return mapping.findForward("builderIndex");

}

}

//写cookie

Cookie newcookie = new Cookie("name", userName1);

newcookie.setDomain("boyincn.com");

newcookie.setMaxAge(60 * 60);

response.addCookie(newcookie);
