Learn in 1 Hour: Introduction to Spring Framework

Whether it’s your first day of Hour of Code or you’ve been with us since the beginning, we hope you enjoy it to the fullest! Today, we are going to talk about Spring, the single most popular framework for building Java-based web applications and one of the most popular topics at JetBrains Academy.

But before we go into the details, let’s find out what a framework is. Frameworks in programming are structures of reusable code, which developers can use as templates in their own applications to avoid writing everything from scratch.

Spring is an application framework for the Java platform. It helps you build modern web applications with support for microservice architectures, cloud systems, reactive processing, and serverless workloads. The main feature of the Spring Framework is Dependency Injection, which allows developing loosely coupled applications. Loose coupling reduces dependencies between the components and allows for better flexibility and testability of the program, making it easier to maintain. 

The Spring Framework is mostly used for building web applications, but it can also be applied in desktop and even command-line applications. One of the famous examples is Netflix moving its platform almost entirely over to Spring Boot a couple of years ago.

With JetBrains Academy, you can get a solid introduction to the Spring Framework and some of its most important modules in just about an hour! Below, you will find links to our one-hour-long educational topics, which will not only help you learn theory but will also give you a chance to practice your knowledge right away:

🕐 Spring Boot is an extension of the Spring platform that helps build stand-alone applications with minimal additional configurations. It allows developers to avoid a lot of boilerplate code and provides a way to quickly get started with Spring-based applications.

🕐 Spring MVC is basically a view layer technology that acts as a controller for HTML and handles HTTP requests. It is mostly used to create websites and RESTful services and to provide readily-available components that simplify and speed up the development process.

🕐 Spring Data focuses entirely on data and object mapping and is designed to support a simple and unified way for data access. It makes it easy to use data access technologies, relational and non-relational databases, MapReduce frameworks, and cloud-based data services.

🕐 Spring Security is a module of the Spring framework that deals with authentication and authorization (or access control). It stands between the client and the application, intercepts all requests, and allows limiting the data available to users. Overall, it is an important tool to protect your app against common security vulnerabilities and attacks.
