怎么獲取HttpServletResponse response
@RequestMapping(value?=?"/logincheck"?,?method?=?RequestMethod.POST)
public?String?login(HttpServletResponse?response,
????????????????????@RequestParam(value?=?"UserName",required?=?true)?String?UserName,
????????????????????@RequestParam(value?=?"PassWord",required?=?true)?String?PassWord){
????System.out.println(response.getHeaderNames()+"hhhh");
????UserDemo?userDemo?=?new?UserDemo();
????userDemo.setUserName(UserName);
????userDemo.setPassWord(PassWord);
????if(loginService.login(userDemo,response).equals("SUCCESS")){
????????return?"UserOne";
????}
????return?"login";
}里面response為什么是空值

response里沒有這個方法? ?head是你的請求方http協議的請求頭發過來的? 肯定是封裝在request對象里啊? response是你把要回復的信息封裝到這個對象里? 他只能獲得所有和回復有關的信息。所以你得調用request的getheadername方法拿到請求信息
