eureka常见问题

一、自我保护

eureka管理后台出现一串红色字体：是警告，说明有服务上线率低 EMERGENCY! EUREKA MAY BE INCORRECTLY CLAIMING INSTANCES ARE UP WHEN THEY'RE NOT. RENEWALS ARE LESSER THAN THRESHOLD AND HENCE THE INSTANCES ARE NOT BEING EXPIRED JUST TO BE SAFE.

关闭检查方法：eureka服务端配置文件加入

eureka:
    server:
        enable-self-preservation: false

注意：生产环境自我保护模式禁止关闭，默认是开启状态true
