Adding JWT Security to Java Spring Boot API

 JSON Web Token (JWT) pronounced “jat” is an authentication and authorization widely used in modern apps. In this mechanism, when the user logs in with their credentials, the server generates a unique key called the JWT token that it sends to the client. The client would then include the JWT token in the header when it sends a request to a protected endpoint on the server. The server would then verify the JWT token before sending a response to the client. In this tutorial, you will see code samples for how to add JWT security to Java Spring Boot API. The code samples provided here are from a sample project on Github, the link for which will be included in this post. Before starting with the code samples, it would be beneficial to understand JWT in a bit more.
