Final answer:
Spring Boot provides a range of basic annotations such as SpringBootApplication, RestController, and RequestMapping, to simplify configuration and the setup of components. These annotations are core to Spring Boot's philosophy of convention over configuration, streamlining the development process for Spring applications.
Step-by-step explanation:
Spring Boot is a framework that simplifies the bootstrapping and development of new Spring applications. It provides a range of basic annotations to help with configuring your application and wiring up components. Here are some of the core annotations offered by Spring Boot:
- SpringBootApplication: This is a convenience annotation that combines Configuration, EnableAutoConfiguration, and ComponentScan annotations. It indicates a configuration class that declares one or more Bean methods and also triggers auto-configuration and component scanning.
- RestController: This annotation is used at the class level and is a specialized version of Controller. It indicates that the class is a web controller and ensures that return values from methods are automatically bound to the web response body.
- RequestMapping: This annotation is used to map web requests to specific handler classes or handler methods. It can be applied at the class or method level.
- Autowired: This annotation is used to autowire bean on the setter method, constructor, a property, or methods with arbitrary names and/or multiple arguments.
- Service: This indicates that an annotated class is a "Service" component. It is used to mark the class as a service provider.
- Repository: This marks the class as a Data Access Object, which is used to indicate that the class provides the mechanism for storage, retrieval, update, delete and search operation on objects.
- Configuration: Indicates that a class declares one or more Bean methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime.
These annotations are fundamental to Spring Boot's approach to convention over configuration, making it easier to develop Spring applications.
