Class RequestEntity<T>

java.lang.Object

org.springframework.http.HttpEntity<T>

org.springframework.http.RequestEntity<T>

Type Parameters:

T - the body type

Direct Known Subclasses:

RequestEntity.UriTemplateRequestEntity

public class RequestEntity<T>
extends HttpEntity<T>

Extension of HttpEntity that also exposes the HTTP method and the target URL. For use in the RestTemplate to prepare requests with and in @Controller methods to represent request input.

Example use with the RestTemplate:

 MyRequest body = ...
 RequestEntity<MyRequest> request = RequestEntity
     .post("https://example.com/{foo}", "bar")
     .accept(MediaType.APPLICATION_JSON)
     .body(body);
 ResponseEntity<MyResponse> response = template.exchange(request, MyResponse.class);
 

Example use in an @Controller:

 @RequestMapping("/handle")
 public void handle(RequestEntity<String> request) {
   HttpMethod method = request.getMethod();
   URI url = request.getUrl();
   String body = request.getBody();
 }
