How to handle RESTful API requests in SpringBoot?

SpringBoot is a rapid development framework that offers many convenient ways to handle RESTful API requests. In SpringBoot, handling RESTful API requests typically involves using the @Controller or @RestController annotation to mark a class or method as a request handler.

The @Controller annotation is typically used to handle page requests, while the @RestController annotation is typically used to handle RESTful API requests. With classes or methods annotated with @RestController, specific HTTP request methods can be marked using @GetMapping, @PostMapping, @PutMapping, @DeleteMapping, etc., to bind them to their corresponding URL paths.

For example, here is an example of handling a GET request:

The class called ApiController is annotated with @RestController.

@GetMapping("/api/endpoint")
public ResponseEntity<String> handleGetRequest() {
    return ResponseEntity.ok("Hello, World!");
}

In the example above, we defined a class named ApiController which is annotated with @RestController. We then marked the handleGetRequest method with @GetMapping(“/api/endpoint”) to bind it to the path /api/endpoint for GET requests. Finally, the handleGetRequest method returns a ResponseEntity object containing the string “Hello, World!” as the response.

In addition, SpringBoot also offers a range of other features to simplify the development of RESTful APIs, such as using the @RequestBody annotation to access data in the request body, using the @PathVariable annotation to access parameters in the URL path, and using the @RequestParam annotation to access request parameters. Therefore, using SpringBoot to handle RESTful API requests is very simple and convenient.
