[JAVA] Spring Boot --How to set session timeout time

A memorandum on how to set the session timeout period in Spring Boot.


--Spring Boot v2.0.3 (* Spring Session is unused)

Setting method

For JAR builds

Just add the following settings to application.properties. By the way, the settings under server.servlet seem to be the settings for the built-in application server.



For WAR build

The settings under server.servlet in application.properties are settings for the built-in application server, so they are not used for war deployment. In case of war deployment, it can be set by either of the following methods.

How to set in web.xml

Create and configure web.xml.


<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"



It is possible to set the default session timeout for the application server in TOMCAT_HOME / conf / web.xml. However, in most cases you will want to set the session timeout for each application. In that case, create src / main / webapp / WEB-INF / web.xml in the application project.

By the way, if you are using eclipse (STS), if you add / src / main / webapp in the "Deployment Assembly" of the project properties, you can create the web when you start the application with WTP. Happy using .xml.

How to set with HttpSessionListener

Although it is a primitive method, there is also a method to set with HttpSessionListener, which is executed when Session is created / destroyed. However, if you just want to set the session timeout time, it seems redundant, so I think it is better to specify it in web.xml.


public class HttpSessionListenerImpl implements HttpSessionListener {

    public void sessionCreated(HttpSessionEvent se) {
        HttpSession session = se.getSession();
        //Set session timeout time in seconds

    public void sessionDestroyed(HttpSessionEvent se) {


public class WebAppConfig {
    // ...
