How to Create a Spring Boot Project in Spring Initializr and Run it in IntelliJ IDEA?
Here's a step-by-step guide to creating a Spring Boot project using Spring Initializr and running it in IntelliJ IDEA:
1. Create a Spring Boot Project using Spring Initializr:
- Open a web browser and navigate to https://start.spring.io/.
- Choose the desired project type (typically "Maven Project").
- Select the desired version of Spring Boot.
- Fill in the "Project Metadata":
- Group: Your organization or group name (e.g.,
com.example) - Artifact: The name of your project (e.g.,
demoapp)
- Add dependencies as needed. These are libraries/frameworks you want to use in your project. For a simple web application, you might choose "Spring Web".
- Click the "Generate" button. This will download a
.zip file containing the project structure and files. - Extract the
.zip file to a location of your choice.
2. Open and Run the Project in IntelliJ IDEA:
- Open IntelliJ IDEA.
- Select "Open" or "Import Project" from the main window.
- Navigate to the location where you extracted the
.zip file. - Choose the extracted project directory and click "OK".
- IntelliJ IDEA will recognize the project as a Maven (or Gradle) project and will automatically start importing the required dependencies. If not, you can trigger this process by right-clicking on the
pom.xml file (for Maven projects) and selecting "Reload Project". - Once the project is imported and all dependencies are downloaded, locate the main application class. By default, it's named
DemoappApplication.java (or similar, based on your artifact name) and resides in the src/main/java/com/example/demoapp directory. - Right-click on the main application class and select "Run" or click the green triangle (play button) in the margin next to the class declaration. This will start your Spring Boot application.
- If you added the "Spring Web" dependency, you can open a browser and navigate to
http://localhost:8080 to see your running application.
Note: IntelliJ IDEA has excellent support for Spring Boot, so you'll benefit from features like auto-completion, integrated documentation, and more as you develop your Spring Boot application.
Remember to regularly check for updates to both Spring Boot and any dependencies you've added, to ensure you're using secure and up-to-date versions.
