application.properties 配置
server.port=9990
eureka.instance.hostname=localhost
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
##暴露eureka服务的地址
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/
#自我保护模式,当出现出现网络分区、eureka在短时间内丢失过多客户端时,会进入自我保护模式,即一个服务长时间没有发送心跳,eureka也不会将其删除,默认为true
eureka.server.enable-self-preservation=false
# 暴露监控端点
