Spring Boot Session Timeout Redirect To Login Page

Posted on by



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

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. 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.

What you'll build

Register account
Log in
Log out
Welcome

What you'll need

Your local computer should have JDK 8+ or OpenJDK 8+, Maven 3+, MySQL Server 5+ or Docker CE 18+

You should also walk through the following tutorials if you are new to Spring Boot, JSP and Spring Data JPA

Init project structure

You can create and init a new Spring Boot project by using Spring CLI or Spring Initializr. Learn more about using these tools here

The final project structure as below

Project dependencies

Define JPA and Hibernate Entities

@Entity is a JPA annotation which specifies the class as an entity (so the class name can be used in JPQL queries)

@Table annotation with the name attribute specifies the table name in the underlying database for the annotated entity. If no @Table is defined, the class name of the entity will be used as the table name

@Id declares the identifier property of the entity

@ManyToMany defines a many-to-many relationship between 2 entities

mappedBy indicates the entity is the inverse of the relationship

Spring Data JPA Repositories

Spring Data JPA Repositories help you reduce boilerplate code required to implement data access layers for various persistence stores such as MySQL and PostgreSQL

They provide some CRUD functions to query, create, update and delete against the underlying database such as findAll, findById, save, saveAll, delete and deleteAll

Define Spring Security's UserDetailsService

To implement login/authentication with Spring Security, we need to implement org.springframework.security.core.userdetails.UserDetailsService interface

Security Service

We create SecurityService to provide current logged-in user and auto login user after registration

User Service

Provide service for registering account

Define Validator

To provide input-data validation for /registration controller with Spring Validator, we implement org.springframework.validation.Validator. Error codes, e.g. Size.userForm.username, are defined by validation.properties

Controllers

We don't define /login POST controller, it is provided by Spring Security

JSP View Templates with Bootstrap

Define Properties

'hk-mysql' refers to the Docker Compose service defined in the below docker-compose.yml file

spring.jpa.hibernate.ddl-auto=create allows JPA/Hibernate auto create database and table schema for you

In practice, you may like to disable the DDL Auto feature by using spring.jpa.hibernate.ddl-auto=validate or spring.jpa.hibernate.ddl-auto=none (default). Check out this tutorial as one of the approaches Flyway Example of Database Migration/Evolution with Spring Boot, JPA and Hibernate

Web Security Configuration

Application Configuration

Run with Docker

Prepare Dockerfile for Java/Spring Boot application and docker-compose.yml for MySQL Server

Type the below command at the project root directory, make sure your local Docker engine is running

Run with Maven

You can run the app with your local MySQL Server by updating 'hk-mysql' on application.properties to 'localhost' and type the below command at the project root directory

Testing time

Access to localhost:8080 and start playing around with the app

You want to use the following...

Now for as to why you would want to do this is beyond me? If you can check this when the page is being processed on the server you can simply force a redirect like the following...

But i'm assuming this is also not what your after. If you want to check the users session is valid repeatedly e.g every 30 seconds then neither of those methods will work.

The reason being is that once the server has sent the page to the user the session check is calculated and hard-coded into the JavaScript. It will NOT be re-assessed everytime you call the javascript method as it is static.

To perform this you will need two steps, the first is to setup a page to return a flag indicating whether a users session is valid and secondly perform an asynchronous request to fetch the users session state.

First of all create a page e.g. SessionCheck.aspx and add the following...

Secondly add the following script to your existing page...

The above snippets will make a request to the SessionCheck.aspx page, which in turn returns a small parcel of JSON which once the script receives this, evals it into a javascript object so we can access the flag 'valid' which will be true or false depending on whether the user is logged in.

Hope it helps.
