Spring MVC is a popular web framework that provides a robust and easy-to-use model for developing web applications. In this tutorial, we will explore the various types of requests that can be handled by Spring MVC controllers.

Request Types

  1. GET Requests

    • Used to retrieve data from a server.
    • Often used to fetch information without changing the server's state.
  2. POST Requests

    • Used to send data to the server, typically to create or update a resource.
    • Often includes form data or JSON payload.
  3. PUT Requests

    • Used to update a resource on the server.
    • Similar to POST, but intended for updating an existing resource.
  4. DELETE Requests

    • Used to delete a resource on the server.
    • Intended for removing an existing resource.
  5. PATCH Requests

    • Used to apply partial modifications to a resource.
    • Similar to PUT, but only a subset of the resource is updated.

Handling Requests in Spring MVC

To handle requests in Spring MVC, you need to define a controller with methods that correspond to the different HTTP methods. Here's an example of a controller handling various requests:

@Controller
public class RequestController {

    @GetMapping("/getExample")
    public String handleGet() {
        // Logic for handling GET requests
        return "getResponse";
    }

    @PostMapping("/postExample")
    public String handlePost(@RequestBody String data) {
        // Logic for handling POST requests
        return "postResponse";
    }

    @PutMapping("/putExample")
    public String handlePut(@RequestBody String data) {
        // Logic for handling PUT requests
        return "putResponse";
    }

    @DeleteMapping("/deleteExample")
    public String handleDelete() {
        // Logic for handling DELETE requests
        return "deleteResponse";
    }

    @PatchMapping("/patchExample")
    public String handlePatch(@RequestBody String data) {
        // Logic for handling PATCH requests
        return "patchResponse";
    }
}
