GetMapping("/rest/v1/books") in spring rest api

Sure! Here is a response explaining each step of using the GetMapping annotation in a Spring REST API:

1. Import the necessary dependencies: In your Spring project, you need to import the required dependencies for building REST APIs. This typically includes the Spring Web dependency, which provides the necessary classes and annotations for creating REST endpoints.

2. Define your controller class: Create a controller class that will handle the HTTP requests for your REST API. Annotate the class with @RestController to indicate that it is a REST controller.

3. Create a method for handling the GET request: Inside your controller class, create a method that will handle the GET request for the /rest/v1/books endpoint. Annotate the method with @GetMapping("/rest/v1/books") to map the GET request to this method.

4. Implement the method logic: Inside the method, write the logic to handle the GET request. This could involve retrieving data from a database, calling external APIs, or performing any other necessary operations.

5. Return the response: After processing the request, return the appropriate response. This could be a single object, a list of objects, or any other data structure that represents the response.

6. Test the API: Once your controller is set up, you can test the API using tools like Postman or by sending HTTP requests directly. Send a GET request to the /rest/v1/books endpoint and verify that you receive the expected response.

That's it! By following these steps, you can use the GetMapping annotation in a Spring REST API to handle GET requests for the /rest/v1/books endpoint.
