SpringCloud服务比较快的下线配置

# eureka server刷新readCacheMap的时间,client读取的是readCacheMap,默认30s
eureka.server.responseCacheUpdateInvervalMs=3000
#缓存readWriteCacheMap失效时间，因为开启了evict，这个就没起到作用了，默认180s
eureka.server.responseCacheAutoExpirationInSeconds=180
# 服务下线任务定时，默认60s
eureka.server.eviction-interval-timer-in-ms=3000
# 超过这个时间没收到心跳就剔除这个服务，这个配置一般为服务刷新时间配置的三倍，默认90s
eureka.instance.lease-expiration-duration-in-seconds=15
# 服务刷新时间，默认30s
eureka.instance.lease-renewal-interval-in-seconds=5
# eureka client刷新本地缓存时间,默认30s
eureka.client.registryFetchIntervalSeconds=5
# 关闭自我保护
eureka.server.enable-self-preservation=false

eureka.instance.lease-expiration-duration-in-seconds=15
eureka.instance.lease-renewal-interval-in-seconds=5
eureka.client.registryFetchIntervalSeconds=5
