Description: Properties in Spring Boot are key-value pairs used to configure various aspects of an application. These properties are defined in configuration files, such as ‘application.properties’ or ‘application.yml’, and allow developers to adjust the behavior of the application without needing to modify the source code. Properties can cover a wide range of configurations, from database connections, server settings, to customizing security and error handling. This property-based approach facilitates the management of configurations across different environments, such as development, testing, and production, allowing the same application to adapt to various needs without significant changes to its structure. Additionally, Spring Boot provides a flexible configuration system that allows properties to be overridden through environment variables or command-line arguments, further enhancing its versatility and ease of use. In summary, properties in Spring Boot are essential for configuring and customizing applications, offering a clear and efficient way to manage configuration centrally.
