Retrieve sslService from Service Registry

You retrieve the sslService from the service registry by using a plug-in.

Procedure

1. Using a plug-in, invoke the getService() method from IServiceRegistry and retrieve an ISslService interface.
   Note:

   If the plug-in is Spring-based, you can define the service dependencies, or auto-wire, ISslService.

   import ch.dunes.vso.sdk.IServiceRegistryAdaptor;
   import ch.dunes.vso.sdk.ssl.ISslService;
   public final class PluginAdaptor implements IServiceRegistryAdaptor {
    @Override
    public void setServiceRegistry(IServiceRegistry registry) {
    ISslService sslService = (ISslService)
   registry.getService(IServiceRegistry.SSL_SERVICE);
    }
   }

2. After you retrieve the sslService, assign the service reference as a field.
   In this way, the plug-in does not search in the registry, every time it uses the service. sslService provides two interfaces - SslContext and HostNameVerifier.

   public interface ISslService {
    SSLContext newSslContext(String protocol) throws NoSuchAlgorithmException;
   
    HostnameVerifier newHostNameVerifier();
   }
   

3. Create a new SslContext object and specify the desired protocol.

   SSLContext sslContext = sslService.getSslContext("TLS");

4. Create an SSLSocketFactory class.

   SSLSocketFactory factory = sslContext.getSocketFactory();

   The factory class creates a socket with some specified options: host, port, autoClose, localAddress, localPort, and localhost.

5. Set SSLSocketFactory to an HTTPS connection.

   URL url = new URL(serverUrl); //a string with some serverUrl
   URLConnection connection = url.openConnection();
   HttpsURLConnection httpsConnection = (HttpsURLConnection) connection;
   SSLContext sslContext = sslService.newSslContext("TLS");
   httpsConnection.setSSLSocketFactory(sslContext.getSocketFactory());
   httpsConnection.setHostnameVerifier(sslService.newHostNameVerifier());

6. When a URLConnection is open, use the HostNameVerifier interface.

   URL url = new URL(serverUrl); //a string with some serverUrl
   URLConnection connection = url.openConnection();
   HostnameVerifier hostnameVerifier = sslService.newHostNameVerifier();
   ((HttpsURLConnection) connection).setHostnameVerifier(hostnameVerifier);
