- org.springframework.http.HttpEntity<T>

类型参数:: T - the body type

直接已知子类:: RequestEntity, ResponseEntity

public class HttpEntity<T>
extends 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("https://example.com", entity);

or

 HttpEntity<String> entity = template.getForEntity("https://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);
 }

从以下版本开始:: 3.0.2
