# Commonly Used Annotations ## About Spring Framework provides a rich set of annotations that reduce boilerplate code and make configuration, dependency injection, request mapping, and many other aspects of application development more declarative and expressive. This section groups together the annotations that developers frequently interact with while building Spring Boot applications across different layers of the application — including configuration, web, service, data access, and Spring Boot-specific behavior. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
