添加cookie

cookie phone；

phone = new Cookie("userHp", hp);
  phone.setMaxAge(60 * 60 * 24 * 365);
  phone.setPath("/");
  ServletActionContext.getResponse().addCookie(phone);

获取cookie

public String getCookieValue(Cookie[] cookies, String str) {
  String result = null;
  for (Cookie cookie : cookies) {
   if (cookie.getName().equals(str)) {
    result = cookie.getValue();
    break;
   }
  }
  return result;
 }

通过请求获取页面上的cookie，分别读取cookie值
// 删除cookie   
        public Cookie delCookie(HttpServletRequest request) {  
             request = ServletActionContext.getRequest();   
           Cookie[] cookies = request.getCookies();  
           if (cookies != null) {  
               for(int   i=0;i<cookies.length;i++)   
               {
                   if("userName".equals(cookies[i].getName()) ||"userHp".equals(cookies[i].getName()) || "password".equals(cookies[i].getName())) {
                        Cookie cookie = new Cookie(cookies[i].getName(), "");
                        cookie.setMaxAge(0);
                        cookie.setPath("/");
                       ServletActionContext.getResponse().addCookie(cookie);
                       //return cookie;
                   }
                   
               }
            }  
            return null;  
        }  
然后获取session调用删除cookie的方法就可以删除
HttpSession session = ServletActionContext.getRequest().getSession();
           if (session != null) 
               session.removeAttribute("userName");
                    session.removeAttribute("userHp"); 
                    delCookie(this.getRequest());

if(password.trim().matches("^[\u4e00-\u9fa5]+$")&&!password.trim().matches("^[[email protected]]+$")){
   this.addActionError("请重新输入密码,不能用特殊符号和中文！");
   return ERROR;
  }

if(!hp.trim().matches("1[3458][0-9]{9}")){
   this.addActionError("手机号有问题，请重新输入！");
   return ERROR;
}

if(!name.trim().matches("^[a-zA-Z0-9_\u4e00-\u9fa5]+$")){
   this.addActionError("用户名不能用特殊符号！");
   return  ERROR;
 }
