springboot session timeout setting in azure app service

Question

springboot session timeout setting in azure app service

shin.ou 1

my spring boot project worked well with the following setting in the local env.

server.servlet.session.timeout: 180m

but when i released the jar to the azure as app service. session time-out became to a default time(1800s).
request.getSession().getMaxInactiveInterval() = 1800

where can i set the session time in azure, or wheather azure support the setting ?

some one who can give some advice? thanks.

@shin.ou The 30 minute timeout is a default value for Spring Boot, but this is not modified by Azure Spring Cloud. How was the default overridden? Also, are you using Azure App Service or Azure Spring Cloud?

@shin.ou Thank you for the clarification! Let me update the tag so this can get seen by people who specialize in Azure App Services.

@shin.ou , are you generating a jar or a war file? Is your app service Windows hosted or Linux? Which Java environment runtime is your app service (embedded, Tomcat 8.5 or Tomcat 9)?

Hi @shinou,

I'm not sure if you're deploy via .jar or .war but according to this Stackoverflow post, session timeout setting may or may not be used and seems to work when Spring Boot uses an embedded Tomcat as the web container. If you're deploy your app as a WAR file, your setting will not be honored unless a web.xml file is created with a configuration.
