Spring Boot Learning Notes

Welcome to my Spring Boot learning repository! Here, I document my journey as I dive into the world of Spring Boot development. Below, you'll find notes, code snippets, and resources I've gathered along the way.

Overview

Spring Boot is a powerful framework for building Java-based applications with minimal configuration. It simplifies the process of creating standalone, production-grade Spring-based applications, allowing developers to focus more on business logic rather than boilerplate code.

Getting Started

If you're new to Spring Boot, here's a quick guide to get you started:

  • Install Java and Maven/Gradle on your system.
  • Create a new Spring Boot project using Spring Initializr or your preferred IDE.
  • Explore the project structure and configuration files.
  • Start building your application by adding controllers, services, and repositories.

Key Concepts

As I progress in my learning journey, I've encountered several key concepts in Spring Boot:

  • Dependency Injection: Spring Boot leverages dependency injection to manage the components of your application, promoting loose coupling and easier testing.
  • Auto-configuration: Spring Boot provides automatic configuration for common application setups, reducing the need for manual configuration.
  • Spring Data: Integrating with Spring Data makes it easy to work with databases in your Spring Boot applications, supporting various databases and reducing boilerplate code.
  • RESTful APIs: Spring Boot simplifies the creation of RESTful APIs using annotations like @RestController and @RequestMapping.

Examples

Here are some examples of code snippets I've created while learning Spring Boot:

Hello World Controller

@RestController
public class HelloWorldController {

    @GetMapping("/hello")
    public String hello() {
        return "Hello, Spring Boot!";
    }
}
