Answer
By overriding properties in application.properties.
Environment variables can override properties defined in Spring Boot's application.properties by using the ${} syntax. This is crucial for deploying applications in different environments without changing the code. For instance, setting a variable like export DB_URL=jdbc://prod.db allows the application to pick it up automatically.
