启动 CoAP 服务器后,我需要动态添加新资源。但是我必须停止并再次启动服务器才能访问新资源。我想添加新资源与在已经启动的 HTTP 服务器中添加新的 HTTP servlet 相同。
这里我添加了用于添加动态资源的源代码。如果我在这里遗漏任何东西,请告诉我。
private static CoapServer server;
public CoAPEventAdapter(InputEventAdapterConfiguration eventAdapterConfiguration,
Map<String, String> globalProperties) {
this.eventAdapterConfiguration = eventAdapterConfiguration;
this.globalProperties = globalProperties;
if(server == null){
server = new CoapServer();
server.start();
}
}
@Override
public void connect() {
registerDynamicEndpoint(eventAdapterConfiguration.getName());
isConnected = true;
}
private void registerDynamicEndpoint(String adapterName) {
server.stop();
server.add(new HelloWorldResource(adapterName));
server.start();
}
class HelloWorldResource extends CoapResource {
public HelloWorldResource(String resourceName) {
// set resource identifier
super(resourceName);
// set display name
getAttributes().setTitle("Hello-World Resource");
}
@Override
public void handleGET(CoapExchange exchange) {
// respond to the request
exchange.respond("Hello World!");
}
}
