Spring 引导执行器发现端点返回 404

Question

I'm running into an issue of Spring Boot Actuator not exposing discovery page with the links to exposed actuators. At the same time, I'm able to access actuators such as info , health and metrics .

I'm using Spring Boot 2.1.8 and my application.yml looks like this:

info:
  artifact: spring-actuator-example
  name: Spring Boot Actuator Example
  description: Spring Boot Actuator Example
  version: 1.0.0

#Exposes Spring actuator endpoints
management:
  server:
    port: 7979
    servlet:
      context-path: /actuator
  endpoint:
    health:
      show-details: always
  endpoints:
    web:
      base-path: /
      exposure:
        include: "*"

If I try to access /actuator endpoint I get

{
  timestamp: "2019-09-18T19:55:25.622+0000",
  status: 404,
  error: "Not Found",
  message: "No message available",
  path: "/actuator/"
}

instead of something like

{
  "_links": {
    "self": { 
      "href": "http://localhost:7979/actuator",
      "templated": false
    },
    "info": { 
      "href": "http://localhost:7979/actuator/info",
      "templated": false
    },
    "health": { 
      "href": "http://localhost:7979/actuator/health",
      "templated": false
    },
    "metrics": { 
      "href": "http://localhost:7979/actuator/metrics",
      "templated": false
    }
  }
}

Is there any configuration I'm missing?

I have created a small example project here for you to try it out.
