Springcloud Problem Resolution: Spring-cloud-eureka startup error cannot execute request on any known server

Scene:

When starting Eureka server, the following error occurred:

Com.sun.jersey.api.client.ClientHandlerException:java.net.ConnectException:Connection refused: Connectcom.netflix.discovery.shared.transport.TransportException:Cannot execute request on any known server

Problem solving:

View Profile application.yml, find the Register-with-eureka property value set to True, change it to false, restart the Eureka service, start successfully, solve the problem

Reason:

Under the default settings, the Eureka Service registry will also attempt to register itself as a client, so we need to disable its client registration behavior:

Eureka:  instance:    hostname:localhost  client:    Registerfalse    fetch  false

Summarize:

If the client registration behavior of the Eureka Service registry is not disabled, a Service-url registry address is required:

Server:   8091Eureka:  instance:    hostname:localhost  client:    Registertrue     Fetch false #注册中心地址    service-URL:      defaultzone:http://${ eureka.instance.hostname}:${server.port}/eureka/
