The problem was found in the springboot project production session-out timeout.

However, I received feedback from customers at noon that the project expiration time was set to be short. If no operation is performed for half an hour, the session will expire and require repeated logins.

In order to solve this problem, we need to use some techniques and methods to achieve cross-domain sharing of sessions. 1. The most common use of cookies to share sessions across domains

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.
