org.apache.http.conn.ConnectTimeoutException：连接到 localhost:8761 超时

Question

当将 ureka 端口号从默认端口更改为自定义端口时，运行 eureka 客户端显示错误。

    eureka.client.registerWithEureka=true
    eureka.client.fetchRegistry=true

这是application.properties文件内容

    # serivce name
    spring.application.name=student-service
    # port
    server.port=6161
    # eureka server url
    eureka.client.service-url.defaultZone=http://localhost:6969/eureka
    eureka.client.registerWithEureka=true
    eureka.client.fetchRegistry=true

正在显示

com.sun.jersey.api.client.ClientHandlerException: org.apache.http.conn.ConnectTimeoutException: Connect to localhost:8761

Answer 1

在 eureka 注册表服务器中添加属性如下所述：

  client:
  registerWithEureka: false
  fetchRegistry: false
  serviceUrl:
  defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
