Spring Tutorial
Last modified: June 19, 2021
The Spring Framework is a mature, powerful and highly flexible framework focused on building web applications in Java.
One of the core benefits of Spring is that it takes care of most of the low-level aspects of building the application to allow us to actually focus on features and business logic.
Another strong point is that, while the framework is quite mature and well-established, it's very actively maintained and has a thriving dev community. This makes it quite up to date and aligned with the Java ecosystem right now.
Of course, there's a lot to learn to work well with Spring.
Let's get started.
