• It includes a range of pre-configured and starter dependencies that provide common application features, such as data access, security, and web services.
• It provides built-in support for packaging and deploying Spring applications as standalone executable JAR or WAR files.
• It provides a range of features and tools for managing and monitoring the runtime behavior of Spring applications, including health checks, metrics, and logging.
• It provides a range of plugins and integrations with popular build and deployment tools, such as Maven, Gradle, and Docker, making it easy to integrate with existing build and deployment pipelines.
