spring security+sso 认证通过后跳转原始路径

我们访问一个域名+路径（需要授权访问）时，如果没有登录会返回一个登录页面，登录完成后我们希望继续访问之前输入的域名+路径，我的实现方案如下：

前端：1.没有授权时访问（这里页面肯定会报错），2.弹出登录界面，这两个动作过程中必须确定前端一定会调用某个接口，然后和后端协商，通过这个接口将浏览器地址栏内容（即原始路径）放到http header中传递到后端。

前端代码不再展示，主要逻辑就是，获取地址栏地址然后放到header里面通过接口发送到后端。

后端：使用过滤器，优先级设置为-101，因为security过滤器优先级为-100，因此在security过滤器之前生效。
