客户端服务器中的JmDNS服务发现

服务器端：

mdnsServer = JmDNS.create(localhost);// Register a test service.ServiceInfo testService = ServiceInfo.create("my-service-type", "Test Service", 6666, "test service");mdnsServer.registerService(testService);

客户端：

private ServiceListener mdnsServiceListener = new ServiceListener() {  public void serviceAdded(ServiceEvent serviceEvent) {    // Test service is discovered. requestServiceInfo() will trigger serviceResolved() callback.    mdnsService.requestServiceInfo(Constants.mdnsServiceType, serviceEvent.getName());  }  public void serviceRemoved(ServiceEvent serviceEvent) {    // Test service is disappeared.  }  public void serviceResolved(ServiceEvent serviceEvent) {    // Test service info is resolved.    String serviceUrl = serviceEvent.getInfo().getURL();    // serviceURL is usually something like http://192.168.11.2:6666/my-service-name};mdnsService = JmDNS.create();mdnsService.addServiceListener("my-service-type", mdnsServiceListener);ServiceInfo[] infos = mdnsService.list(Constants.mdnsServiceType);// Retrieve service info from either ServiceInfo[] returned here or listener callback method above.mdnsService.removeServiceListener("my-service-type", mdnsServiceListener);mdnsService.close();

一旦有了URL

http://192.168.11.2:6666/myTestService
