Open it, and you’ll see a typical standalone Spring Boot starter app. You can quickly access files by hitting Ctrl-Shift-P and typing “Demo” to bring up the DemoApplication.java file. You will see a default “not found” error page because we haven’t defined any routes yet, but this verifies that the server is up and listening. You can verify this by opening a browser and going to localhost:8080.

When that’s done, the dev server will be running. The first time you do this, Maven will download your new dependencies. In the terminal, type mvn spring-boot:run.

Installing the Spring Initializr extension IDG Type in “spring init” and you’ll see the Spring Initializr Java Support extension. This will let you search for available add ons (and there are a lot of them). Open VS Code and click the extensions icon on the bottom left. You are going to use Spring Initializr to create a new Spring Boot Web app. Now let’s jump right in with a new project.
