Remove 'jsessionid=xxxx' from URL in Spring Boot App

Add the following configuration to your JavaConfig:

@Bean
ServletContextInitializer servletContextInitializer() {
    // keep session only in cookie so that jsessionid is not appended to URL.
    return servletContext -> servletContext.setSessionTrackingModes(
            Collections.singleton(SessionTrackingMode.COOKIE));
}

This is equivalent to

<session-config>
    <tracking-mode>COOKIE</tracking-mode>
</session-config>

in web.xml

@nicolas_frankel With 1.3 there is a property: `server.session.tracking-modes=cookie`
