not getting headers passed with RestTemplate.getForObject

I am newbie using Spring . I am working on a code trying to pass headers using restTemplate.getForObject

client side :

String userServiceUrl = "http://localhost:8080/SampleRest/api/user/";
HttpHeaders headers = new HttpHeaders();
headers.set("Authorization", UUID.randomUUID().toString() );
restTemplate.getForObject(userServiceUrl + "{id}",User.class,HttpMethod.GET,headers) ;

however on server the request header "Authentication" is not passed at all . there is no header "Authentication"

requestHeaders.get("Authorization").get(0) //yields null exception

I cannot use restTemplate.exchange

what am I doing wrong ?

Help will greatly appreciated

We can use it in Spring boot for GET Method in the below manner :

@SpringBootApplication

public class Application implements CommandLineRunner{

private static final Logger log = LoggerFactory.getLogger(Application.class);

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

@Override
public void run(String... args) throws Exception {
    try{
    RestTemplate restTemplate = new RestTemplate();
    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders = this.createHeaders();
    ResponseEntity<String> response;
    response  = restTemplate.exchange("<url>",HttpMethod.GET,new HttpEntity<Object>(httpHeaders),String.class);
    log.info(response.toString());
    }
    catch(Exception e)
    {
        System.out.println("Exception"+e);
    }


}

private HttpHeaders createHeaders(){
    HttpHeaders headers =  new HttpHeaders(){
          {            
             set( "Authorization", "3ee140");
          }
       };

       return headers;
}

}

There is no option to pass headers in getForObject method of restTemplate.

You can implement ClientHttpRequestInterceptor to set the headers if you don't want to use exchange. You can also overwrite SimpleClientHttpRequestFactory
