    official documents: http: //cloud.spring.io/spring-cloud-netflix/single/spring- cloud-netflix.html # spring-cloud- eureka-server

    step 1: create project
    step two: add annotations @EnableEurekaServer
    The third step: to increase the allocation application.yml

the format of the suffix into yml


copy the code official documents of the case in the past.

server:
  port: 8761

eureka:

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