org.springframework.http

Class RequestEntity<T>

java.lang.Object

org.springframework.http.HttpEntity<T>

org.springframework.http.RequestEntity<T>

Type Parameters:

T - the body type

public class RequestEntity<T>
extends HttpEntity<T>

Extension of HttpEntity that adds a method and uri. Used in RestTemplate and @Controller methods.

In RestTemplate, this class is used as parameter in exchange():

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

If you would like to provide a URI template with variables, consider using UriTemplate:

 URI uri = new UriTemplate("http://example.com/{foo}").expand("bar");
 RequestEntity<MyRequest> request = RequestEntity.post(uri).accept(MediaType.APPLICATION_JSON).body(body);
 

Can also be used in Spring MVC, as a parameter in a @Controller method:

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