Mastering Spring Boot Security with JWT

Securing APIs is a critical aspect of modern web development. In the Spring Boot ecosystem, Spring Security provides a robust framework for handling authentication and authorization. When combined with JSON Web Tokens (JWT), you can create stateless, scalable, and secure applications.

What is JWT?

JWT is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed.

Setting up the Project

First, you'll need to add the necessary dependencies to your pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt-api</artifactId>
    <version>0.11.5</version>
</dependency>

This is just the beginning. The full implementation involves creating a JWT utility class, configuring Spring Security, and creating authentication endpoints. Stay tuned for more!
