Welcome to the Spring Boot Getting Started guide! This tutorial will walk you through creating a simple Spring Boot application and deploying it. 🌐

What is Spring Boot? 📚

Spring Boot is a framework that simplifies building microservices and REST APIs with Java. It provides default configurations and embedded servers (like Tomcat) to reduce boilerplate code. 🌱

Step-by-Step Guide 🧰

  1. Set Up Project
    Use Spring Initializr to generate a project structure.

  2. Add Dependencies
    Include Spring Web and Spring Data JPA in your pom.xml file.

    Maven

  3. Create REST API
    Define a controller class with @RestController and @GetMapping annotations.
    Example: 

    @RestController
public class HelloController {
    @GetMapping("/hello")
    public String sayHello() {
        return "Welcome to Spring Boot!";
    }
}

  4. Configure Database
    Set up application.properties for MySQL or PostgreSQL. 

    spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.jpa.hibernate.ddl-auto=update

  5. Run and Deploy
    Use mvn spring-boot:run to start the app. Deploy via Docker or cloud platforms like AWS.
