Learn Java Spring Boot in 5 minutes | SpringBoot REST API Tutorial
Hi there, and welcome to this tutorial on learning Java Spring Boot in just 5 minutes!

Spring Boot is a popular framework for building web applications with Java. It makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run".

In this tutorial, we'll be building a simple REST API using Spring Boot.

To get started, you'll need to have the following installed on your machine:

Java JDK 8 or higher
Maven
An IDE, such as Eclipse or IntelliJ IDEA

Once you have these tools set up, we can begin.

First, let's create a new Maven project in our IDE. Choose "maven-archetype-quickstart" as the project archetype and give your project a name.

Next, we'll need to add the Spring Boot starter dependency to our project. Open the pom.xml file and add the following dependency:

@GetMapping("/greeting")
public String Greeting() {
return "Hello, This is Java Spring Boot Tutorial";
}
}

That's it! You now have a basic REST API built with Spring Boot. You can test it by running your application and sending a GET request to the "/hello" path.

I hope you found this tutorial helpful. With just a few lines of code, you can quickly build powerful and scalable web applications with Java and Spring Boot. Thanks for watching!
