addCookie时中文出错
Cookie   userCookie   =   new   Cookie(ContextConfigure.USER_COOKIE_NAME,user.getLoginname());
                userCookie.setMaxAge(   60   *   60   *   24   *   30   );

                userCookie.setPath( "/ ");
.WSAY_DOMAIN   );
                passwordCookie.setPath( "/ ");
                response.addCookie(   userCookie   );//userCookie中包含中文时怎么会出错误呢？
错误信息为：
