Spring Boot is a popular framework for building Java-based applications, and Visual Studio Code (VS Code) is a powerful, lightweight code editor that supports Java development. In this blog, we'll walk you through creating a Spring Boot project in VS Code, setting up a package structure, and running your application.
Prerequisites
Before we start, make sure you have the following installed:
- Java Development Kit (JDK): You can download it from Oracle's official site or use OpenJDK.
- Maven: You can download it from Maven's official site.
- Visual Studio Code: Download it from here.
- VS Code Extensions: Install the following extensions:
Step 1: Create a Spring Boot Project
Open VS Code and open the integrated terminal by pressing
Ctrl +
` (backtick).Generate a Spring Boot project using Maven with the following command:
sh
mvn archetype:generate -DgroupId=com.example -DartifactId=myproject -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
Alternatively, you can use the Spring Initializr website to generate a project. Download the project as a ZIP file, extract it, and open the folder in VS Code.
Step 2: Open the Project in VS Code
Open the project folder in VS Code. You can do this by navigating to
File > Open Folder
and selecting the project directory.Open the terminal in VS Code (if itβs not already open) by pressing
Ctrl +
(backtick).
Step 3: Create Packages
Navigate to the
src/main/java
directory in your project explorer.Create new packages by right-clicking on the
java
directory, selectingNew Folder
, and naming it according to your package structure (e.g.,com/example/myproject
).
Step 4: Add Classes to Your Package
Right-click on the package you just created (e.g.,
com/example/myproject
) and selectNew File
.Name the file (e.g.,
MyClass.java
) and press Enter.Define your class within this file. For example:
`java
package com.example.myproject;
public class MyClass {
public static void main(String[] args) {
System.out.println("Hello, Spring Boot!");
}
}
`
Step 5: Configure Spring Boot
Ensure you have a main application class to run your Spring Boot application. It should be in the root package or a subpackage of it.
Example Application.java
in the root package com.example.myproject
:
`java
package com.example.myproject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
`
Step 6: Run Your Spring Boot Application
Open the integrated terminal in VS Code by pressing
Ctrl +
(backtick).Navigate to the project directory if not already there.
Use Maven to run your application:
sh
mvn spring-boot:run
Alternatively, you can build your project and run the jar file:
sh
mvn package
java -jar target/myproject-0.0.1-SNAPSHOT.jar
Summary
By following these steps, you can create a package structure in your Spring Boot project using VS Code, add classes, configure your application, and run it successfully. This setup allows you to organize your project code logically and maintainably.

The article, from step 5 that had to do with creating an application class is not clear
It seems like you were rushing to complete the article without regard for your readers from that point.
