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
GET Requests
- Used to retrieve data from a server.
- Often used to fetch information without changing the server's state.
POST Requests
- Used to send data to the server, typically to create or update a resource.
- Often includes form data or JSON payload.
PUT Requests
- Used to update a resource on the server.
- Similar to POST, but intended for updating an existing resource.
DELETE Requests
- Used to delete a resource on the server.
- Intended for removing an existing resource.
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";
}
}
