How to load custom properties files in Spring Boot

Date: 2024-01-15

Spring Boot's @PropertySource annotation allows loading external property files, separating configuration from code. It specifies the location of files containing key-value pairs, enabling customization without code changes. While application.properties is loaded by default, @PropertySource is used for custom files (e.g., custom.properties) located on the classpath, specified via classpath:custom.properties. Multiple files can be loaded using @PropertySources. @Value injects properties into beans. This improves application flexibility and maintainability.
