        PeerAwareInstanceRegistry registry = EurekaServerContextHolder.getInstance().getServerContext().getRegistry();
        Applications applications = registry.getApplications();
        // 便利获取已注册节点中与当前失效节点ID一致 的节点信息
        applications.getRegisteredApplications().forEach(registryApplication -> {

                if (Objects.equals(instance.getInstanceId(), event.getServerId())) {
                    log.info("服务:{}挂啦。。。", instance.getAppName());
                // emailService.send(new SimpleMailMessage());
                }
            });
        });
    }
    if (applicationEvent instanceof EurekaInstanceRegisteredEvent) {
        EurekaInstanceRegisteredEvent event = (EurekaInstanceRegisteredEvent) applicationEvent;
        log.info("服务:{}注册成功啦。。。", event.getInstanceInfo().getAppName());
    }
    if (applicationEvent instanceof EurekaInstanceRenewedEvent) {

        log.info("心跳检测服务：{}。。。", event.getInstanceInfo().getAppName());
    }
    if (applicationEvent instanceof EurekaRegistryAvailableEvent) {
        log.info("服务 Available。。。");
    }
}

Example 2 with EurekaInstanceRegisteredEvent

    final LeaseInfo leaseInfo = getLeaseInfo();
    final InstanceInfo instanceInfo = getInstanceInfo(APP_NAME, HOST_NAME, INSTANCE_ID, PORT, leaseInfo);
    // calling tested method
    instanceRegistry.register(instanceInfo, false);
    // event of proper type is registered
    assertEquals(1, this.testEvents.applicationEvents.size());

    assertFalse(registeredEvent.isReplication());
}

Example 3 with EurekaInstanceRegisteredEvent

use of org.springframework.cloud.netflix.eureka.server.event.EurekaInstanceRegisteredEvent in project spring-cloud-netflix by spring-cloud.

the class InstanceRegistryTests method testDefaultLeaseDurationRegisterEvent.

@Test
public void testDefaultLeaseDurationRegisterEvent() throws Exception {
    // creating instance info
    final InstanceInfo instanceInfo = getInstanceInfo(APP_NAME, HOST_NAME, INSTANCE_ID, PORT, null);
    // calling tested method
    instanceRegistry.register(instanceInfo, false);
    // instance info duration is set to default
    final EurekaInstanceRegisteredEvent registeredEvent = (EurekaInstanceRegisteredEvent) (this.testEvents.applicationEvents.get(0));
    assertEquals(LeaseInfo.DEFAULT_LEASE_DURATION, registeredEvent.getLeaseDuration());
