SpringCloud启动eureka server后，没报错却不能访问管理页面（404的解决办法）

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：
