Lighty Spring.io Dependency Injection Extension

This project provides Lighty Core module for Spring.io Dependency Injection Extension. This extension is available for Lighty projects application projects using Spring.io as runtime environment.

io.lighty.core.controller.spring.LightyCoreSpringConfiguration

How to use it

1. Add dependency into your project

   <dependency>
      <groupId>io.lighty.core</groupId>
      <artifactId>lighty-controller-spring-di</artifactId>
   </dependency>

2. Extend LightyCoreSpringConfiguration class to apply lighty.io services bean configuration and initialize LightyController as spring bean with whichever custom configuration you want

@Configuration
public class LightyConfiguration extends LightyCoreSpringConfiguration {

    private static final Logger LOG = LoggerFactory.getLogger(LightyConfiguration.class);

    @Override
    protected LightyController initLightyController() throws LightyLaunchException, InterruptedException {
        try {
            LOG.info("Building LightyController Core");
            final LightyControllerBuilder lightyControllerBuilder = new LightyControllerBuilder();
            final Set<YangModuleInfo> mavenModelPaths = new HashSet<>();
            mavenModelPaths.addAll(NetconfConfigUtils.NETCONF_TOPOLOGY_MODELS);
            final LightyController lightyController = lightyControllerBuilder
                    .from(ControllerConfigUtils.getDefaultSingleNodeConfiguration(mavenModelPaths))
                    .build();
            LOG.info("Starting LightyController (waiting 10s after start)");
            final ListenableFuture<Boolean> started = lightyController.start();
            started.get();
            LOG.info("LightyController Core started");

            return lightyController;
        } catch (ConfigurationException | ExecutionException e) {
            throw new LightyLaunchException("Could not init LightyController", e);
        }
    }

    @Override
    protected void shutdownLightyController(@Nonnull LightyController lightyController) throws LightyLaunchException {
        try {
            LOG.info("Shutting down LightyController ...");
            lightyController.shutdown();
        } catch (Exception e) {
            throw new LightyLaunchException("Could not shutdown LightyController", e);
        }
    }
    ...
}

3. Inject & use ODL services in your code

@RestController
@RequestMapping(path = "netconf")
public class NetconfDeviceRestService {

    private static final InstanceIdentifier<Topology> NETCONF_TOPOLOGY_IID = InstanceIdentifier
        .create(NetworkTopology.class)
        .child(Topology.class, new TopologyKey(new TopologyId("topology-netconf")));
    private static final long TIMEOUT = 1;
    private static final InstanceIdentifier<Toaster> TOASTER_IID = InstanceIdentifier.create(Toaster.class);

    @Autowired
    @Qualifier("BindingDataBroker")
    private DataBroker dataBroker;

    @Autowired
    private MountPointService mountPointService;

    ...
}
