I'm developing an application with Spring Boot and Spring Security by starting the Application class in Eclipse with an embedded Tomcat. Every time I restart the server, my session disappears and I have to log in again which becomes quite annoying.
Is it possible to persist the sessions between server restarts?
I saw this other question on Stackoverflow where someone asks the opposite, which makes me think that this should actually work out-of-the-box:
How to disable Tomact session persistence in Spring Boot via Manager pathname?
I'm running Spring Boot 1.2.1 with Gradle.
btw, I know about Spring Loaded, but sometimes a server restart is unavoidable.
I just figured this out myself. Everytime the application is started, Spring generates a new random temporary directory in /tmp for Tomcat's base directory (e.g. /tmp/tomcat.5990562997404648887.8080). Since it uses a different folder on each start, Tomcat has no way to restore the session.
This can be worked around by setting your own base directory with server.tomcat.basedir=/tmp. However, I don't consider this a fix since it requires setting an operating system specific directory, so I opened a bug about this: https://github.com/spring-projects/spring-boot/issues/2490
