Spring: how to redirect to login page on session timeout. Greenhorn Posts: 1. Posted 9 years ago. I am pretty new to spring, have set session timeout of 1 minute in the web.xml. I need to display the login page once session is timed out and user clicks any link in the application. This tutorial will walk you through the process of creating a simple User Account Registration and Login Example with Spring Boot, Spring Security, Spring Data JPA, Hibernate, MySQL, JSP, Bootstrap and Docker Compose What you'll build Register account Log in Log out Welcome What you'll need Your local computer should. A common requirement for a web application is to redirect different types of users to different pages after login. An example of this would be redirecting standard users to a /homepage.html page and admin users to a /console.html page for example. This article will show how to quickly and safely implement this mechanism using Spring Security.
When browser caches the resources then clicking on the browser’s back button will take a user to the login page again and it gives bad experience to the users.
Spring Boot Security - Redirect to different pages after Login using AuthenticationSuccessHandler Example In a previous post we had implemented Spring Boot Security - Database Authentication. In some scenarios we might want to redirect different users to different pages depending on the roles assigned to the users. Krishna, it depends on what version of Spring Boot you are using. The server.session.timeout no longer works in Spring 2.x, which requires server.servlet.session.timeout. Keep in mind this will only work in embedded Tomcat, not standalone. For that, you have to manually set the session timeout in the Tomcat server.xml.
Even if the user presses the browser’s back button it will take him/her to the login page if the user is not already logged in otherwise it will take the user to the logged in home page or dashboard page.
Prerequisites
Knowledge of web application, Java, Servlet
So here I am going to give you the code snippets to prevent it and for this I am going to write a servlet filter.

Servlet Filter
I am going to write the below servlet filter class to prevent user going back to the login page.
In the above Servlet Filter I am retrieving a Login object and checking for null and redirecting user to the appropriate page. A Login object is a simple POJO class that holds login information like username, email etc.
Web pages such as login.jsp, home.jsp etc. are kept into webapp/pages/ directory of the web application.
So using Servlet Filter you are easing your checking task to automatically redirect a user to the home page.
Deployment Descriptor – web.xml
I have put the required servlet filter entry into the deployment descriptor file – web.xml. I have also configured URL pattern, session timeout, welcome page for the application.
If you don’t want to use web.xml you can use annotation on Servlet Filter as shown in the following example.
