In this video, we will understand how configuration works in Spring Boot from the very basics. Most beginners write values directly inside Java code, but in real-world applications, values like server port, database URL, username, password, application name, custom messages, and environment-specific settings should not be hardcoded. That is where Spring Boot configuration comes in. In this video, we will cover: Why configuration is needed in real-world applications Problems with hardcoding values in Java code What is application.properties How to use @Value annotation Limitations of .properties file Introduction to YAML Difference between .properties and .yml YAML indentation rules How to convert properties into YAML Lists and nested configuration in YAML Why Spring Profiles are needed application-dev.yml, application-prod.yml, and profile-specific files How to activate profiles using properties, command line, and environment variables Difference between profile-specific files and @Profile annotation How @Profile creates beans conditionally based on environment By the end of this video, you will clearly understand how the same Spring Boot application can run with different configurations in different environments like dev, test, staging, and production. This is one of the most important concepts for writing professional Spring Boot applications.
