后退页的数据怎么不被丢失
后退页的数据如何不被丢失
因为需求，从A页提交数据到B页后，在B页上想做个后退按扭，发现用JS的history.back()是不行的。
在B页上有隐藏的表单，都是记录A页的表单各值的。
但都是在一个FORM里边，FORM的action是把本form的表单都发送到我要指定的一个程序页面。
所以我开始想利用FORM上做文章，把那些从A页传来的 ‘在B页上隐藏的表单值’再传回去。但是只有一个FORM
请教大家，如何办？让点‘后退’再回到A页上，还显示原来的N多表单的数据
------解决方案--------------------
在b页面里再写个FORM2，action=a.php，里面放需要传回去的hidden，点后退的时候commit FORM2

可以使用session来保存。
单单的退回，有的浏览器会保存，有的则不会。
用session就可以做到所有都有保存

How to set session timeout in SpringBoot Session
May 15, 2023 pm 02:37 PM
The problem was found in the springboot project production session-out timeout.

How to solve the problem that the Springboot2 session timeout setting is invalid
May 22, 2023 pm 01:49 PM
Problem: Today, we encountered a setting timeout problem in our project, and changes to SpringBoot2’s application.properties never took effect. Solution: The server.* properties are used to control the embedded container used by SpringBoot. SpringBoot will create an instance of the servlet container using one of the ServletWebServerFactory instances. These classes use server.* properties to configure the controlled servlet container (tomcat, jetty, etc.). When the application is deployed as a war file to a Tomcat instance, the server.* properties do not apply. They do not apply,
