HttpClientErrorException: 401 Unauthorized basic authentication

Question

Im trying to get the url with basic authentication. I set the user/password as given below. The same credential is working in postman.

String RELATIVE_IDENTITY_URL  = "http://my_url/api/core/v3/people/email/abc@example.com";
    RestTemplate restTemplate;
    Credentials credentials;

    //1. Set credentials
    credentials = new UsernamePasswordCredentials("admin", "admin");

    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials( AuthScope.ANY, credentials);

    //2. Bind credentialsProvider to httpClient
    HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
    httpClientBuilder.setDefaultCredentialsProvider(credsProvider);
    CloseableHttpClient httpClient = httpClientBuilder.build();

    HttpComponentsClientHttpRequestFactory factory = new  
            HttpComponentsClientHttpRequestFactory(httpClient);

    //3. create restTemplate
    restTemplate = new RestTemplate();
    restTemplate.setRequestFactory(factory);

    //4. restTemplate execute
    String url = RELATIVE_IDENTITY_URL;

    String xml = restTemplate.getForObject(url,String.class); 
    System.out.println("Done");

I think the credentials are not set correctly. What is wrong here.? Error:

When you make the request how do you attach the credentials and are you setting the auth header? — Mike Tung, May 31 '17 at 12:53
@MikeTung: I just missed to add that. I really thought it would be taking from the Set credentials part above. its working when I set it via headers. Thanks much — Nidheesh, May 31 '17 at 13:11

You are missing the auth header and setting the credentials in your rest template execution.
