DESCRIPTION

Demonstration of how you can capture the starting events of the application, creation of the user session and destruction of the user's session.

If you want to create web applications with Spring about Apache Tomcat 10 it is better that you use Spring Boot. (Locate my repositories on web applications with Spring Boot 3).
