Description: Application properties in Spring Boot are key configurations that allow customization of an application’s behavior. These properties are commonly defined in files like ‘application.properties’ or ‘application.yml’, where developers can specify settings related to the database, server, security, and other aspects of the runtime environment. The flexibility of these properties enables developers to tailor their application to different environments, such as development, testing, and production, without needing to modify the source code. Additionally, Spring Boot provides a set of default properties that facilitate initial configuration, allowing developers to focus on business logic rather than infrastructure. Properties can include configurations such as server port, database URL, access credentials, and performance parameters, among others. This dynamic configuration capability is one of the features that has contributed to the popularity of Spring Boot, as it simplifies the deployment and maintenance process of applications built with the Java platform. In summary, application properties are fundamental for the customization and optimization of Spring Boot applications, providing an efficient means to manage configurations across different environments.
