• Deployment: Deployment involves making your application available on the server. For Java applications, this typically means packaging your app into a WAR (Web Application Archive) or JAR (Java Archive) file.
• WAR/JAR File: WAR (Web Application Archive) and JAR (Java Archive) are files used to package Java applications for distribution.

Steps to Install Spring Boot Application in Hostinger

Step 1: Build Your Spring Boot Application

First, you need to package your Spring Boot application. Depending on your deployment preference, you can create either a JAR or WAR file. Use the following Maven command to build the application:

mvn clean package

This command compiles your project and packages it into a .jar or .war file in the target directory.

Step 2: Access Hostinger Control Panel

Log in to your Hostinger account and navigate to the control panel (hPanel).

Step 3: Upload the Application File

In the hPanel, go to the File Manager and navigate to the public_html directory. Upload your .jar or .war file here.

Go to the public_html directory.

Upload your .jar or .war file to this directory.

Step 4: Configure Java Environment

Hostinger supports Java applications via the Java Web (Tomcat) option. If you haven’t configured this yet:

1. Go to Domains > Manage your Website.

2. Under Websites, go to Advanced section, select Java Web (Tomcat).

3. Follow the on-screen instructions to set up the environment, ensuring that the appropriate version of Java is selected.

Step 5: Deploy the Application

After uploading your application file, go to the Java Applications section in the hPanel. Select the uploaded .war file and click Deploy.

Step 6: Start the Application

Once the deployment is complete, start the application from the Java Applications section. Check to ensure it runs without errors.

Step 7: Access Your Application

Your Spring Boot application should now be accessible at http://yourdomain.com/application-name.

Example:

Consider a simple Spring Boot application that provides a RESTful API. Here’s a basic example:

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String sayHello() {
        return "Hello, World!";
    }
}

After deploying this application to Hostinger, accessing http://yourdomain.com/hello should return “Hello, World!”.
