将以下属性添加到application.properties可以解决此问题，您可以尝试一下。

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

答案 1 :(得分：0)

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

并确保半角字符
