Present-day apps depend on user authentication, which can be challenging for Java developers. Many developers build their own authentication service as a placeholder for a more powerful option only for that homegrown service to become a permanent solution. Through this post, I will show you how to integrate an enterprise auth service to a simple app as a solution to ending this heartbreak of a cycle.
We’ll create an app that showcases user information. We’ll manually compose the authentication in the app to see the downsides. We’ll then move to the enterprise-auth solution. By the end of this post, you’ll learn how to secure a working Spring app using OAuth 2.0 for authentication in just 5 minutes.
