struts中Cookie实现记住密码

HttpServletRequest request = ServletActionContext.getRequest();
	        Cookie[] cookies = request.getCookies();
		if(number.equals("")==false) {
			//创建Cookie
			 Cookie cookie = new Cookie("Number", number);
			 //设置Cookie的生命周期
			 cookie.setMaxAge(60*60*24*365);
			 ServletActionContext.getResponse().addCookie(cookie);
		}
		else if(cookies!=null){
			for(int i=0; i<cookies.length; i++) {
	        	if(cookies[i].getName().equals("Number"))
	        		number=cookies[i].getValue().toString();
	        }
		}
		if(password.equals("")==false) {
			//创建Cookie
			 Cookie cookie = new Cookie("Password", password);
			 //设置Cookie的生命周期
			 cookie.setMaxAge(60*60*24*365);
			 ServletActionContext.getResponse().addCookie(cookie);
		}
		else if(cookies!=null){
			for(int i=0; i<cookies.length; i++) {
	        	if(cookies[i].getName().equals("Password"))	
	        		password=cookies[i].getValue().toString();
	        }
		}
