类 HttpEntity<T>

  • 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);
 }
