Class HttpEntity<T>

java.lang.Object

org.springframework.http.HttpEntity<T>

Direct Known Subclasses:

RequestEntity, ResponseEntity

public class HttpEntity<T>
extends java.lang.Object

Represents an HTTP request or response entity, consisting of headers and body.

Typically used in combination with the RestTemplate, like so:

 HttpHeaders headers = new HttpHeaders();
 headers.setContentType(MediaType.TEXT_PLAIN);
 HttpEntity<String> entity = new HttpEntity<String>(helloWorld, headers);
 URI location = template.postForLocation("http://example.com", entity);
 

or

 HttpEntity<String> entity = template.getForEntity("http://example.com", String.class);
 String body = entity.getBody();
 MediaType contentType = entity.getHeaders().getContentType();
 

Can also be used in Spring MVC, as a return value from a @Controller method:

 @RequestMapping("/handle")
 public HttpEntity<String> handle() {
   HttpHeaders responseHeaders = new HttpHeaders();
   responseHeaders.set("MyResponseHeader", "MyValue");
   return new HttpEntity<String>("Hello World", responseHeaders);
 }
