skywalking接入例子错误，且尝试修复后也没采集到信息

会找不到ObservationRegistry observationRegistry这个bean，然后我声明了一个之后服务能运行了，但是也采集不到dubbo的信息

我的代码：
```
@Configuration
public class ObservationConfiguration {

@Bean
ObservationRegistry observationRegistry() {
// Here we create the Observation Registry with attached handlers
ObservationRegistry registry = ObservationRegistry.create();
// Here we add a meter handler
registry.observationConfig()
.observationHandler(new ObservationHandler.FirstMatchingCompositeObservationHandler(
(ObservationHandler) new SkywalkingMeterHandler(new SkywalkingMeterRegistry())
));
return registry;
}

@Bean
ApplicationModel applicationModel(ObservationRegistry observationRegistry) {
ApplicationModel applicationModel = ApplicationModel.defaultModel();
observationRegistry.observationConfig()
.observationHandler(new ObservationHandler.FirstMatchingCompositeObservationHandler(
new SkywalkingSenderTracingHandler(), new SkywalkingReceiverTracingHandler(),
new SkywalkingDefaultTracingHandler()
));
applicationModel.getBeanFactory().registerBean(observationRegistry);
return applicationModel;
}
}
```
