Creating a Spring Boot Project

Following are the steps to create a simple Spring Boot Project.

Step 1: Open the Spring initializr https://start.spring.io.

Step 2: Provide the Group and Artifact name. We have provided Group name com.w3cschoool and Artifact spring-boot-example.

Step 3: Now click on the Generate button.

When we click on the Generate button, it starts packing the project in a .rar file and downloads the project.

Step 4: Extract the RAR file.

Step 5: Import the folder.

File -> Import -> Existing Maven Project -> Next -> Browse -> Select the project -> Finish

It takes some time to import the project. When the project imports successfully, we can see the project directory in the Package Explorer. The following image shows the project directory:

SpringBootExampleApplication.java

package com.w3cschoool.springbootexample;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootExampleApplication 
{
public static void main(String[] args) 
{
SpringApplication.run(SpringBootExampleApplication.class, args);
}
}
