spring-cloud - Spring Cloud - Registry Service 端口定制

Question

我想用 Spring Cloud 自定义 Eureka 端口。
使用下面的默认端口，服务注册表可以正确看待自己(在提供的 GUI 中)

spring:
  application:
    name: services-registry
server:
  port: 8761

eureka:
  instance:
    hostname: localhost
    nonSecurePort: ${server.port}
  client:
    register-with-eureka: true
    fetch-registry: false
    service-url:
      default-zone: http://${eureka.instance.hostname}:${server.port}/eureka/

但是如果我只是将 server.port 更改为 8787，则没有服务可以自行注册，甚至服务注册表本身也无法注册。

有人可以解释这个问题并挽救我的一天吗？谢谢!

好的，明白了... service-url 属性(在 YML 中可以别名为 serviceUrl)之后的标签是一个 HashMap key ，不是属性标签。所以它必须以任何方式保存为 Camel Case 标签!

eureka.client.service-url.defaultZone=http://[myIP@]:8787/eureka
