Introduction to Spring Boot
Explore how Spring Boot enhances Java application development by automating configuration, managing dependencies through inversion of control, and embedding web servers. Understand how this framework streamlines building scalable, maintainable backend applications by focusing on business logic instead of infrastructure.
Throughout this course, we have built everything by hand. When we needed an object, we created it with new. When we needed a file, we opened a stream. We managed the lifecycle of every component ourselves.
In production environments, building large-scale systems without leveraging existing frameworks is usually not practical. We rely on tools that manage infrastructure concerns such as threading, database connectivity, and embedded web servers, so we can focus on application business logic. Spring Boot addresses this need. As a leading java web application framework, it provides opinionated defaults and auto-configuration to simplify the structure and deployment of Java applications.
Why use a framework?
In earlier lessons, we wrote repetitive setup code just to get a program running. For a small console application, this is manageable. In a production web application, the setup grows quickly and becomes harder to manage.
Spring Boot builds on Spring’s Inversion of Control (IoC) container to manage this setup for us. When using a library, our code calls the library’s ...
