Great article! I was able to build my first spring boot project. This is the stuff I'm completely interested in, but didn't know how to get started. This helped immensely! A couple things to note for others attempting this:
To get this working in Intellij, you need to close all projects and click on the "Open or Import" option. Intellij will then automatically detect everything and start building dependencies. If you were like me, you tried to do File > New Project and kept hitting a roadblock.
You will need a Postman account- They have a free tier that you can sign for. Don't expect Postman to work without the desktop agent, though. Sign up for Postman here and download the desktop agent here (download links are at bottom of the blog post).
This was fun! I think my next step will be to figure out how to make this into an actual website where you can enter a URL and check it and return the status.
