Spring Boot 1.5.9.RELEASE - Eureka verwendet Hostname anstelle von ipaddress, obwohl es in application.yml

Question

Ich habe eine Stand-alone-Spring-Boot-Anwendung (Version - 1.5.9.RELEASE), die ein Client bei Eureka registriert ist Server. Die applicaiton.yml Datei, die vom Frühjahr Boot-Anwendung erforderlich ist, sieht aus wie unter

spring: 
    application: 
    admin: 
     jmx-name: hello-server 

server: 
    port: 8070 
    address: 10.12.134.54 

eureka: 
    client: 
    register-with-eureka: true 
    fetch-registry: true 
    availability-zones: 
     local: http://10.12.134.54:8070/eureka/ 
    instance: 
    prefer-ip-address: true 
    hostname: localhost 

Aber wenn ich die Anwendung zu starten, schlägt es mit Eureka-Server registrieren, weil sie die Hostnamen verwendet: Port statt IP-Adresse: Port.

Kann mir jemand vorschlagen, wie Sie dieses Problem loswerden? Hier

ist das Fehlerprotokoll

Answer 1

Das folgende ist mein Eureka Client config:

eureka: 
    client: 
    serviceUrl: 
     defaultZone: ${DISCOVERY_URL:http://discovery-service:8761}/eureka/ 
    registry-fetch-interval-seconds: 6 
    instance-info-replication-interval-seconds: 6 
    register-with-eureka: true 
    fetch-registry: true 
    heartbeat-executor-thread-pool-size: 5 
    eureka-service-url-poll-interval-seconds: 10 
    instance: 
    leaseRenewalIntervalInSeconds: 10 
    leaseExpirationDurationInSeconds: 20 
    prefer-ip-address: true 

this helps
