java.lang.IllegalStateException: getAttribute: Session already invalidated 会话失效 异常解决
项目中使用到了编辑视频的工具，其中就有一个功能为视频转码，需要转换的时间很长所以就会报错异常
java.lang.IllegalStateException: getAttribute: Session already invalidated
翻译过来就是会话无效
百度了一下基本会照成Session无效这样的情况有两种
（1）Session timeout；会话时间超时
（2）程序中调用了session.invalidate()方法。是将session设置为失效，一般在退出时使用

前端请求后台方法时开始时间 2022-10-13 09:21:17.957
视频处理成功后的时间 2022-10-13 09:23:20.714
时间花费了将近2分钟，但是前端请求设置的会话时间才60秒 =1分钟 所以当后台处理完视频后在去获取请求时生成的Session 就会报错，无法找不到Session。
解决方案及效果
针对超时时间的设置，有两种方法可以解决这个问题，
（1） 在Servlet代码中，使用HttpSession对象的方法setMaxInactiveInterVal(int)设置一个会话维持非活动状态的最大秒数。代码如下：
public void doGet( HttpServletRequest req ,HttpServletResponse res) throws
ServletException,IOException {
HttpSession session=req.getSession();
session.setMaxInactiveInterval(60);
}
（2）.在web.xml文件内通过使用session-config标志设置，通过标志session-timeout可以定义所有非活动HttpSession对象存在的最大时间。
