Question

我有一个独立的spring boot应用程序（版本 - 1.5.9.RELEASE），它是一个客户端注册到Eureka服务器。 spring boot应用程序所需的applicait.yml文件如下所示

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

但是当我启动应用程序时，它无法向Eureka服务器注册，因为它使用的是hostname：port而不是ipaddress：port。

有谁能建议我如何摆脱这个问题？

这是错误日志

Answer 1

以下是我的Eureka客户端配置：

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

希望这有帮助

Spring Boot 1.5.9.RELEASE - Eureka使用主机名而不是ipaddress，尽管它在application.yml中强制使用
