@PostMapping is a Spring annotation used to map HTTP POST requests onto specific handler methods in a controller class. It is used to handle a form submission or to submit data to the server using the HTTP POST method.
The @PostMapping annotation is used with the following syntax:
```
@PostMapping("/endpoint-url")
public ResponseEntity<ResponseObject> handlerMethod(@RequestBody RequestObject requestObject) {
//code to handle the request and generate a response
}
```
The @PostMapping annotation takes the URL endpoint as its parameter, which is the URL that the request should be sent to. The handler method takes a request object as input, which is annotated with @RequestBody to indicate that it should be parsed from the request body.
The handler method can return a ResponseEntity object, which is used to wrap the response object and any HTTP status codes or headers that should be returned in the response.
Overall, @PostMapping is a powerful Spring annotation that allows developers to easily handle HTTP POST requests and process form submissions or other types of data on the server.
