Spring Security Tutorial


The Spring security tutorial will help you understand the basics of this framework. You’ll learn about its essential components and the SecurityContext interface, which stores security-related information. You’ll also learn about the Authentication object used to authenticate a user. The developer does not modify these components, but they’ll be required in third-party authentication models.

User Details interface

In this spring security tutorial, you will learn how to use the User Details interface in a Spring application. This interface is responsible for storing and retrieving user details. It takes two parameters: username and password. By calling the GetUserDetails method, you can retrieve the current user’s details.

Users can be members of one or more groups. Each group can be mapped to a role in Spring Security. For example, if the user is an admin, they will have the authority ROLE_ADMIN or ROLE_CALLCENTER. Likewise, a call center user will need to have the control ROLE_CALLCENTER.

The user details are stored in the SecurityContext object. This object is obtained from a SecurityContextHolder. Then, cast this object into UserDetails. Spring Security uses this object to store user information.


The first step in building an authentication service in the Spring Security tutorial is defining your security beans. Each type of bean has a different purpose, and if you don’t specify the appropriate one, Spring Security will throw an exception. For example, this tutorial will use the JDBC-user service to fetch a user’s credentials from a database.

Authentication is crucial to secure the web application’s resources. By implementing the correct authentication scheme, you can ensure that only authorized users are allowed access to your application. A simple login form backed by a fixed list of users can be secured using Spring Security. You can follow a Spring security tutorial starting from scratch to learn how to secure your login form in no time at all. To use this tutorial, you’ll need to install the required libraries and initialize your application.

Session management

Using Spring security, you can authenticate users and allow them to have more than one session open at a time. However, if a user tries to log in multiple times, their session will end when the timer expires. To fix this issue, you can invalidate the session and reauthenticate the user with a new session.

When using this method, you can specify an expiration time and the maximum number of authenticated users. You can also set an error URL. For example, if the user attempts to log in more than three times, the system will redirect them to the authentication failure URL.


This Spring security tutorial will introduce the basics of this framework and the various features and advantages of using it. The tutorial will also include a working example demonstrating a user login page creation. Finally, the tutorial will provide the reader with the basic knowledge required to build a secure application using the framework.

Spring Security provides several useful security features when designing a web application. It was first developed by Ben Alex in 2003 and was released as version 2.0.0 in 2004. The idea behind its creation was to address the problems of developing security applications in a non-spring background, which often results in issues implementing the application and managing the new server environment.

Auth0 integration

You can use Auth0 to integrate Spring security with your web applications. You can get an API token, a JWT, from the Auth0 servers and pass it to your Spring boot application as the Authorization header. The Auth0 libraries will validate the payload and set up the Spring security context. The tutorial uses Java and Groovy languages.

The Auth0 integration process is straightforward. Firstly, you create a controller to render a view. Then, you create an Auth0 Universal Login page, redirecting users to a page where they can sign in using their existing credentials or a social provider. Then, you can turn them back to your application and verify that they are logged in.
