What is Spring Boot?

Spring Boot is a Java-based framework that simplifies the development of Spring applications by reducing boilerplate code, handling dependencies, and providing an embedded server. It follows a convention-over-configuration approach, making it easy to create standalone, production-ready applications with minimal setup.

What is Spring Boot?

🌟 Key Features of Spring Boot

✅ Auto-configuration – Automatically configures Spring components based on dependencies.
✅ Embedded Servers – Comes with Tomcat, Jetty, and Undertow, eliminating the need for external deployment.
✅ Starter Dependencies – Provides predefined dependencies like spring-boot-starter-web, simplifying project setup.
✅ Production-Ready – Includes built-in monitoring, metrics, and health checks via Spring Actuator.
✅ Microservices Support – Ideal for developing REST APIs and microservices.
✅ Spring Boot CLI – Command-line interface to quickly develop and run Spring Boot applications.

🚀 How Does Spring Boot Work?

Spring Boot uses:
📌 Spring Boot Starters – Pre-configured dependencies for different functionalities.
📌 Spring Boot AutoConfiguration – Automatically configures beans based on classpath dependencies.
📌 Embedded Servers – Runs applications without requiring external web servers like Tomcat.

🛠️ Setting Up a Spring Boot Project

You can create a Spring Boot project using:
1️⃣ Spring Initializr → https://start.spring.io/
2️⃣ Maven or Gradle

Example Spring Boot application using Maven:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

Example Spring Boot Application (Java):

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

📌 Why Use Spring Boot?

✔ Reduces Development Time – No need for complex XML configurations.
✔ Easy Deployment – Run with a simple java -jar myapp.jar command.
✔ Microservices-Friendly – Works seamlessly with Spring Cloud for distributed systems.
✔ Highly Scalable – Supports enterprise applications with ease.
