[FIXED] Spring4 MVC keep session alive forever

Issue

I have a scenario where session is getting expired after some time of inactivity, But i need to keep Spring 4 MVC keep session alive forever. Below is my Spring Initializer class,

'''public class SpringWebAppInitializer implements WebApplicationInitializer {

@Override
public void onStartup(ServletContext servletContext) throws ServletException {
    AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
    appContext.register(ApplicationContextConfig.class);

    ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
            "SpringDispatcher", new DispatcherServlet(appContext));
    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("/");

}

}'''

Solution

Use -1 in tag because -1 is for session never expires.

Web.xml:

<session-config>
    <session-timeout>-1</session-timeout>
</session-config>
