How to Create Spring Boot Project

Posted By :Shivani Chaudhary |30th April 2020

What do you want to build?

Here, I want to print a sentence and when I entered my name then it should my name.


Project Requirements

1. An Integrated Developer Environment (IDE). Popular choices include IntelliJ IDEA, Spring Tools, Visual Studio Code, or Eclipse, and many more if have a choice.

2. A Java™ Development Kit (JDK), I recommend AdoptOpenJDK version 8 or version 11.


Step 1: Create a Spring Boot Project

Use to build a “web” project. In the “Dependencies” search box during and append the “web” dependency as shown in the screenshot given below. click on the “Generate” button, then you need to download the zip. After download unpack it into a folder on your computer.

The current version of Spring boot exchanges regularly. Simply choose the latest release (but not snapshot).

Click on 'Add dependencies', type 'Web' in the search box, then click on the dependency 'Spring Web' to choose it.


Projects created by include Spring Boot, a framework that gives Spring ready to work inside your app, but without much code or configuration required. Spring Boot is the instantly and most popular way to start Spring projects.


Step 2: Create a new file and Add your code

Open up the project in your IDE and locate the file in the src/main/java/com/example folder. Now replace the contents of the file by adding the extra method and annotations shown in the code below. You can copy and paste the code and also just type it.

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

public class Application {

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

   public String example(@RequestParam(value = "name", defaultValue = "welcome to spring world!") String name) 
     return String.format("Hello %s!", name);

The example() method we’ve added is designed to get a String parameter called name, and then join this parameter with the word "Hello" in the code. This means that if you set your name to “Shivani” in the request, the response would be “Hello Shivani”.

The @RestController annotation indicates Spring that the code represents an endpoint that should be done available over the web. The @GetMapping(“/hello”) tells Spring to use our example() method to answer requests that get sent to the http://localhost:8080/hello address. Finally, the @RequestParam is telling Spring to expect a name value in the request, but if it’s not there, it will use the wordwelcome to spring the world!by default.

Step 3: Execute code

Let’s build the project and execute the program. Open a command line (or terminal) or you can do right click in same file and select run -> Java Application only) and navigate to the folder where you have the project files. We can build and run the application by resulting the following command:


./mvnw spring-boot:run


mvnw spring-boot:run


You will see some output that looks like very similar to this while hit this URL http://localhost:8080/hello:

Hello welcome to the spring world
