The annotations are grouped by theme and presented in a table format. This cheat sheet provides an overview of the most commonly used Spring Boot annotations. You can use this annotation to configure your application without hardcoding values in your code. This annotation is used to inject values from a properties file or environment variable into a class.When you use this annotation, Spring will automatically create an instance of the dependency and inject it into the class. This annotation is used to inject dependencies into a class.
You can specify the HTTP method (GET, POST, etc.) and the URL path. This annotation is used to map a URL to a method in a controller.It tells Spring that this class will handle HTTP requests and responses. It combines three other annotations: and This annotation is used to mark a class as a REST controller. This annotation is used to mark the main class of your Spring Boot application.Here are some of the most commonly used annotations: There are many annotations available in Spring Boot, each with its own purpose. Annotations are a way to add metadata to your code that can be used by the Spring framework to configure your application. One of the key features of Spring Boot is its support for annotations. It provides a lot of features that make it easy to develop and deploy applications quickly.
Spring Boot is a popular framework for building Java applications.
