Creating a Spring Boot project in Visual Studio Code (VS Code) streamlines the Java development experience. In this article, we’ll explore the steps to set up and build a Spring Boot project in VS Code, ensuring a solid foundation to start developing robust applications.

Step by Step process to the Build a Spring Boot Project in VS Code

Step 1: Ensure that the Java Development Kit(JDK) is installed on the computer system and download and install the Visual Studio Code if not already installed.

Step 2: Install the Java Extension pack and Spring Initializer and Spring Development Tool extension of the VS Code.

Install the Spring Initializr Java Support extension in the VS Code.

Install the Spring Boot Tools extension in VS Code.

Install the Spring Boot Extension pack extension in VS Code.

Step 3: Now, we can open the VS Code and access the Command Palette using the shortcut(Ctrl+shift+P).

type "Spring Initializr: Generate a Maven Project" and enter it.

Step 4: We can choose the version of the Spring Boot application.

Step 5: We can enter the project metadata like the Group, Artifact, Name, Description of the Spring application.

Artifact Id:

Group Id:

Choose the language: Java

Select the Version of the Java

Step 6: We can select the required dependencies needed for the project.

Example: Spring Web, Lombok, Spring DevTools

Step 7: Finally, we can choose the location to the generate the project and click the Generate option to generate the Spring Project.

Step 8: We can open the generated project folder in the VS Code application.

Step 9: Open the main class the add the simple controller method of the Application.

Java

package com.example.demoexample;

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

@SpringBootApplication
@RestController
public class DemoexampleApplication {

    @GetMapping("/hello")
    public String check() {
        return "Hello World";
    }

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

}

Step 10: We can run the application then it will start at port 8080.

Step 11: We can verify the application is running by the accessing the configuration the local server URL.

http://localhost:8080/hello

Output:

By the following the above steps, we can effectively setup, configure and run the Spring Boot project within the Visual Studio Code. It is leveraging its powerful features for the efficient Java development.
