Spring Cloud Eureka 属性配置中文说明文档

 常用配置中文说明文档：

配置参数	默认值	说明
eureka.instance
eureka.instance.prefer-ip-address	true	不使用主机名来定义注册中心的地址，而使用IP地址的形式，如果设置了 eureka.instance.ip-address 属性，则使用该属性配置的IP，否则自动获取除环路IP外的第一个IP地址
eureka.instance.ip-address		IP地址
eureka.instance.hostname		设置当前实例的主机名称
eureka.instance.appname		服务名，默认取 spring.application.name 配置值，如果没有则为 unknown
eureka.instance.lease-renewal-interval-in-seconds	30	定义服务续约任务（心跳）的调用间隔，单位：秒
eureka.instance.lease-expiration-duration-in-seconds	90	定义服务失效的时间，单位：秒
eureka.instance.status-page-url-path	/info	状态页面的URL，相对路径，默认使用 HTTP 访问，如果需要使用 HTTPS则需要使用绝对路径配置
eureka.instance.status-page-url		状态页面的URL，绝对路径
eureka.instance.health-check-url-path	/health	健康检查页面的URL，相对路径，默认使用 HTTP 访问，如果需要使用 HTTPS则需要使用绝对路径配置
eureka.instance.health-check-url		健康检查页面的URL，绝对路径
eureka.server
eureka.server.enable-self-preservation	true	是否开启自我保护，Eureka 会统计15分钟之内心跳失败的比例低于85%将会触发保护机制，不剔除服务提供者，如果关闭服务注册中心将不可用的实例正确剔除
eureka.server.eviction-interval-timer-in-ms	60	server清理无效节点的时间间隔
eureka.dashboard.enabled	true	是否开启仪表盘
eureka.dashboard.path	/	仪表盘访问路径
eureka.client
eureka.client.enabled	true	是否开启client
eureka.client.service-url		指定服务注册中心地址，类型为 HashMap，并设置有一组默认值，默认的Key为 defaultZone；默认的Value为 http://localhost:8761/eureka ，如果服务注册中心为高可用集群时，多个注册中心地址以逗号分隔。 如果服务注册中心加入了安全验证，这里配置的地址格式为： http://<username>:<password>@localhost:8761/eureka 其中 <username> 为安全校验的用户名；<password> 为该用户的密码
eureka.client.fetch-registery	true	是否检索服务
eureka.client.registery-fetch-interval-seconds	30	从Eureka服务器端获取注册信息的间隔时间，单位：秒
eureka.client.register-with-eureka	true	启动服务注册
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
eureka.client.eureka-server-total-connections-per-host	50	从Eureka客户端到每个Eureka服务主机的连接总数
