Spring Boot Java Config Set Session Timeout

You should be able to set the server.session.timeout in your application.properties file.

ref: http://docs.spring.io/spring-boot/docs/1.4.x/reference/html/common-application-properties.html

EDIT:

This property has changed in later versions of Spring Boot to server.servlet.session.timeout.

ref: https://docs.spring.io/spring-boot/docs/2.4.x/reference/html/appendix-application-properties.html#server.servlet.session.timeout

• Spring Boot version 1.0: server.session.timeout=1200
• Spring Boot version 2.0: server.servlet.session.timeout=10m
  NOTE: If a duration suffix is not specified, seconds will be used.

server.session.timeout in the application.properties file is now deprecated. The correct setting is:

server.servlet.session.timeout=60s

Also note that Tomcat will not allow you to set the timeout any less than 60 seconds. For details about that minimum setting see https://github.com/spring-projects/spring-boot/issues/7383.
