Kotlin Spring Boot Tutorial - Part 12 | Database setup
In this Spring Boot tutorial, we continue building our backend application by integrating a real PostgreSQL database using Supabase. After resolving CORS issues in the previous episode with a dedicated configuration class, we now switch from the traditional application.properties file to a more readable and organized application.yml format. This change helps streamline our environment-specific configurations and improves project maintainability.
You’ll learn how to set up and manage environment variables in Spring Boot using YAML syntax, including fallback values to prevent runtime errors. These variables will be essential when deploying the backend to a DigitalOcean Droplet, especially when using Docker images that inject environment variables at runtime.
We walk through the process of configuring the PostgreSQL database connection by retrieving the necessary credentials from Supabase, including host, port, username, and password. You'll also see how to set up your development environment in IntelliJ by defining environment variables directly in the run configuration panel. Once the values are set, we begin preparing the application to connect with the remote database.
This video is ideal for developers looking to connect Spring Boot to a PostgreSQL database using Supabase, organize configuration files with YAML, handle environment variables effectively, and prepare for production deployment on platforms like DigitalOcean. Whether you’re working on a CRUD backend or a larger enterprise application, this step is crucial for database integration and environment readiness.
