SpringCloud启动eureka server,没报错却不能访问管理页面

application.yml：

server:
  port: 8761  #服务器端口

eureka:
  instance:
    hostname: eureka-server #eureka实例的主机名
  client:
    register-with-eureka: false #不把自己（eureka-server）注册到eureka上（不做高可用的情况下）
    fetch-registry: false #不从eureka上来获取服务的注册信息（因为本身就是注册中心，消费者就需要获取提供者的信息）
    service-url:
      defaultZone: http://localhost:8761/eureka/  #不指定默认为http://localhost:8761/eureka.client/

主配置类：

访问http://localhost:8761/eureka/（404错误）

解决办法

去掉eureka/，直接访问http://localhost:8761/

如果还不行，在application.yml里添加

spring.freemarker.prefer-file-system-access: false

试试看。

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
