Creating REST Controllers
Design and implement RESTful endpoints using `@RestController` and various mapping annotations.
Welcome to REST Controllers!
You're about to dive into building powerful web services with Spring Boot! Today, we'll learn how to create RESTful APIs, which are the backbone of modern web applications.
Think of a REST API as a standard way for different computer systems to talk to each other over the internet.
What are RESTful APIs?
REST stands for REpresentational State Transfer. It's an architectural style for networked applications.
- Resources: Everything is a resource (e.g., a user, a product).
- Unique Identifiers: Each resource has a unique URL (e.g.,
/users/123). - Standard Methods: We use standard HTTP methods like GET, POST, PUT, DELETE to interact with resources.
Spring Boot makes implementing these a breeze!
