Before eureka is registered, InstancePreRegisteredEvent will not be published.

[XhstormR]

According to the documentation, there are two events that will be fired when a service auto-registers. The first event, called InstancePreRegisteredEvent, is fired before the service is registered. The second event, called InstanceRegisteredEvent, is fired after the service is registered. You can register an ApplicationListener(s) to listen to and react to these events.

But org.springframework.cloud.netflix.eureka.serviceregistry.EurekaAutoServiceRegistration#start will only publish one InstanceRegisteredEvent, InstancePreRegisteredEvent will never come out.

I see org.springframework.cloud.client.serviceregistry.AbstractAutoServiceRegistration#start will publish those two type of event, but EurekaAutoServiceRegistration is not a subclass of it.
