Spring Cloud Eureka common configuration

Configuration parameters	Defaults	illustrate
Service registry configuration		Bean类：org.springframework.cloud.netflix.eureka.server.EurekaServerConfigBean
eureka.server.enable-self-preservation	false	When the protection mechanism of the registry is turned off, Eureka will count that the percentage of heartbeat failures within 15 minutes is lower than 85%, which will trigger the protection mechanism, and the service provider will not be eliminated. If the service registry is closed, the unavailable instances will be correctly eliminated.
Service instance class configuration		Bean类：org.springframework.cloud.netflix.eureka.EurekaInstanceConfigBean
eureka.instance.prefer-ip-address	false	Do not use the host name to define the address of the registry, but use the form of the IP address, if set eureka.instance.ip-address property, use the IP configured by this property, otherwise automatically obtain the first IP address except the loop IP
eureka.instance.ip-address		IP address
eureka.instance.hostname		Set the hostname of the current instance
eureka.instance.appname		Service name, the default value is spring.application.name , if not, it is unknown
eureka.instance.lease-renewal-interval-in-seconds	30	Defines the calling interval of the service renewal task (heartbeat), in seconds
eureka.instance.lease-expiration-duration-in-seconds	90	Defines the time for service failure, in seconds
eureka.instance.status-page-url-path	/info	The URL of the status page, a relative path. By default, HTTP access is used. If you need to use HTTPS, you need to use an absolute path configuration.
eureka.instance.status-page-url		URL of the status page, absolute path
eureka.instance.health-check-url-path	/health	The URL of the health check page, a relative path. By default, HTTP access is used. If you need to use HTTPS, you need to use an absolute path configuration.
eureka.instance.health-check-url		URL of the health check page, absolute path
Service registration class configuration		Bean类：org.springframework.cloud.netflix.eureka.EurekaClientConfigBean
eureka.client.service-url.		Specify the service registry address, the type is HashMap, and a set of default values ​​are set. The default Key is defaultZone; the default Value is http://localhost:8761/eureka . If the service registry is a high-availability cluster, multiple registrations Center addresses are separated by commas. If security verification is added to the service registry, the format of the address configured here is: http://<username>:<password>@localhost:8761/eureka where <username> is the username for security verification; <password> is the user's password

eureka.client.eureka-server-connect-timeout-seconds	5	连接 Eureka Server 的超时时间，单位：秒
eureka.client.eureka-server-read-timeout-seconds	8	读取 Eureka Server 信息的超时时间，单位：秒
eureka.client.filter-only-up-instances	true	获取实例时是否过滤，只保留UP状态的实例
eureka.client.eureka-connection-idle-timeout-seconds	30	Eureka 服务端连接空闲关闭时间，单位：秒
eureka.client.eureka-server-total-connections	200	从Eureka 客户端到所有Eureka服务端的连接总数
