I recently started learning Spring Boot as part of my backend development journey, and this post marks the beginning of documenting my learning process in public.
Spring Boot is built on top of the Spring Framework, which is a powerful framework used to develop Java enterprise applications. Spring promotes concepts like Dependency Injection (DI) and Inversion of Control (IoC) to create loosely coupled, maintainable, and testable applications. It allows developers to build applications using plain Java objects (POJOs) while still supporting enterprise-level features.
However, while Spring is powerful, setting up a Spring application traditionally involves a lot of manual configuration, XML or Java-based configurations, dependency management, and external server setup.
This is where Spring Boot comes in.
What is Spring Boot?
Spring Boot is an extension of the Spring Framework that simplifies application development by providing:
Auto-configuration based on classpath dependencies
Starter dependencies to reduce dependency management
Embedded web servers like Tomcat or Jetty
Externalized configuration using properties or YAML files
Because of these features, developers can focus more on business logic rather than boilerplate(frequently used code block in coding) configuration
Difference Between Spring and Spring Boot
In simple terms, Spring Boot removes the complexity of setting up Spring applications by handling configuration automatically when certain conditions are met.
Why I’m Learning Spring Boot
Spring Boot is widely used in real-world backend systems and production applications. Understanding how auto-configuration, dependency injection, and application flow work internally is essential for building scalable and maintainable APIs.
Through this blog, I’ll be sharing:

Key backend concepts explained from a learner’s perspective
Common mistakes and practical insights
This is just the beginning, and I’m excited to continue learning and sharing along the way
