Remove the jsessionid after the URL in Spring boot

Inherit SpringBootServletInitializer in the startup class, and then override this method

public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);

        // This will set to use COOKIE only
        servletContext.setSessionTrackingModes(
                Collections.singleton(SessionTrackingMode.COOKIE)
        );
        // This will prevent any JS on the page from accessing the
        // cookie - it will only be used/accessed by the HTTP transport
        // mechanism in use
        SessionCookieConfig sessionCookieConfig =
                servletContext.getSessionCookieConfig();
        sessionCookieConfig.setHttpOnly(true);
    }
