响应Cookie默认返回 SameSite=Lax

作用:不能携带cookie进行跨域post访问

所以导致 浏览器的Cookie-session 机制失效，服务端每次访问都创建新的session

解决方式

@Bean
    public CookieSerializer httpSessionIdResolver()
    {
        DefaultCookieSerializer cookieSerializer = new DefaultCookieSerializer();

        cookieSerializer.setCookieName("SESSION");

        cookieSerializer.setUseHttpOnlyCookie(false);

        cookieSerializer.setSameSite(null);

        return cookieSerializer;
    }
