session也许header均提示有头信息什么的已经输出
session或者header均提示有头信息什么的已经输出。
问题我概括一下吧。
1：一开始是跳转的时候，提示出错，然后我换成HTML的跳转，因为我用的是WAMP集成环境，恐怕是环境问题，也就没大调试。
2：session()的时候，还是提示，我确定前面没有输出，可还是如此提示。我找了如此几个方法进行测试。
有文件包含 （include ***）
1）保存为UTF8为bom模式，依旧，
2）var_dump(headers_sent());如果干掉包含就显示0，不删掉包含文件就显示1.
能力所限，百度已尽，还望大手帮我。

这么简单明了的提示，为什么视而不见呢？

How to set session timeout in SpringBoot Session

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,
