Introducing my “Toolbox” code I will produce examples of common code, this will include code that is often hand crafted at the start of projects..
The code in this project is available at my github and will generally be available under either the MIT licence or the Apache licence to make integrating into code easy.
This section is a work in progress and I will add more code examples in time.
Trivial Authentication with JWT and Spring
I’ll walk you through the creation of a simple authentication system that uses JSON Web Tokens (JWT). The project is divided into two parts: a Spring Boot application that serves as the authentication backend and a Java client that interacts with the secured endpoints. This guide provides an overview of the architecture, key components, and code snippets for both parts of the project.
Introduction
Securing REST APIs is crucial for modern web applications. In this project, I built a minimalistic system that demonstrates how to:
- https://github.com/robdeas/toolbox-trivial-spring-jwt-auth Generate and validate JWT tokens using a Spring Boot backend
- https://github.com/robdeas/toolbox-trivial-java-auth-client Implement a lightweight Java client that interacts with the backend
Whether you’re new to JWT-based security or looking for a refresher on token-based authentication, this example will help understand the key concepts and implementation details.
If you want a fuller implemention of an authentication server please look at my SANDCASTLE-AUTH project, it is much more feature rich, though does not contain all the complexity of a production auth server, its design is based around making it useful for testing and education.
