Get started with Spring Boot in a matter of minutes.

Get your server up and running in a matter of minutes. You will be amazed with the little amount of code you will have to write

Lets begin

Create a simple maven project in Eclipse or any other supported IDE.

Based on the default settiongs of your IDE you will be able to find a class named inside your default package. If not, help yourself and create one.

Remove the boilerplate code and paste the following lines shown below.

public class App {

    public static void main( String[] args)   {, args);

    @RequestMapping(value = "/", method = RequestMethod.GET)
        public @ResponseBody Map<String,Object> hello()  {
        Map<String,Object> response = new HashMap<String, Object>();
        response.put("status", "succcess");
        response.put("message", "Welcome to Spring Boot");
        return response;

What do you see? A lot of errors of course.

That is because we forgot to include the key ingredient.

Open pom.xml and include Spring Boot as a dependency. You can find the maven dependency here

Your IDE will download all the dependencies, if it doesn’t then rght click on your project–Maven–Update Project. You can also press alt+F5.

That is it. That is all the code you have to write. Now run this as a Plain old Java application. The default server port is 8080 hence you can fire up your favourite browser and hit localhost:8080 and voila!!

It’s your first API

Spring will boot up in a matter of seconds

Note: This is not the traditional way of doing this but this post is just meant for you to get started.

We have to create separate classes for the controllers so that all the services are at one place. A detailed post will also cover the basic project structure and will explain about the typical files that you will find in any Spring project.
