Examples with ExceptionEvent org.apache.servicecomb.serviceregistry.event.ExceptionEvent used on opensource projects

Example 1 with ExceptionEvent

use of org.apache.servicecomb.serviceregistry.event.ExceptionEvent in project java-chassis by ServiceComb.

the class MicroserviceWatchTask method doRun.

@Override
public void doRun() {
    // will always run watch when it is ready
    if (!needToWatch()) {
        return;
    }
    srClient.watch(microservice.getServiceId(), (event) -> {
        if (event.failed()) {
            eventBus.post(new ExceptionEvent(event.cause()));
            return;
        }
        MicroserviceInstanceChangedEvent changedEvent = event.result();
        if (isProviderInstancesChanged(changedEvent) && !serviceRegistryConfig.isWatch()) {
            return;
        }
        if (!isProviderInstancesChanged(changedEvent) && !serviceRegistryConfig.isRegistryAutoDiscovery()) {
            return;
        }
        onMicroserviceInstanceChanged(changedEvent);
    }, open -> eventBus.post(new RecoveryEvent()), close -> {
    });
}

            callback.fail(new RuntimeExceptionWithoutStackTrace("test failed"));
        }
    };
    Holder<Throwable> holder = new Holder<>();

        @Subscribe

            holder.value = event.getThrowable();
        }
    });
    Assert.assertNull(holder.value);
    microserviceWatchTask.run();
    Assert.assertEquals("test failed", holder.value.getMessage());
}
