How to send NTLM authenticated post request using jersey?

Question

I am making rest api calls to Sharepoint 2013 using Java. How can I connect to the sharepoint 2013 using jersey rest client?

Note: currently I am using apache http components and NTCredentials class

Credentials credentials=new NTCredentials(username, password, workstation, domain);
AuthScope authScope=new AuthScope(AuthScope.ANY);
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(authScope,credentials);
CloseableHttpClient httpclient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();

How to adopt this to Jersey framework?

Answer 1

The following code executes an NTLM authenticated HTTP GET request that using Jersey:

public Response executeRestGet(String user, String pass) {
    Client client = ClientBuilder.newClient(prepareClientConfig(user, pass));
    WebTarget target = client.target("http://localhost/").path("site/_api/xxxxx");
    return target.request(HTTP_ACCEPT_JSON).get();
}

private ClientConfig prepareClientConfig(String user, String pass) {
    ClientConfig clientConfig = new ClientConfig();

    CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    //make sure to supply all 4 arguments to the  NTCredentials constructor
    credentialsProvider.setCredentials(AuthScope.ANY, new NTCredentials(user, pass, null, null));

    clientConfig.property(ApacheClientProperties.CREDENTIALS_PROVIDER, credentialsProvider);
    clientConfig.connectorProvider(new ApacheConnectorProvider());
    return clientConfig;
}

Please note that this approach requires: jersey-apache-connector. Maven Dependency:
