搭建Admin Server

引入依赖

<project xmlns="http://maven.apache.org/POM/4.0.0"

Admin Server启动类

@EnableAdminServer
@SpringBootApplication
public class MonitorApplication {
    public static void main(String[] args) {
        SpringApplication.run(MonitorApplication.class, args);
    }
}

application.yml配置

server:
  port: 9401
spring:
  application:
    name: learn-monitor
  boot:
    admin:
      monitor:
        default-timeout: 30000

测试

http://127.0.0.1:9401/applications

搭建Admin Client

引入依赖

<!--admin-->
<dependency>
    <groupId>de.codecentric</groupId>
    <artifactId>spring-boot-admin-starter-client</artifactId>
</dependency>

application.yml配置

spring:
  application:
    name: learn-test
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher
  boot:
    admin:
      client:
        url: http://localhost:9401 #配置admin-server地址
management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: always

可能的解决方法：

在application.yml中修改时间，default-timeout: 30000
修改springboot-admin版本
关闭redis，email等服务

management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      show-details: always
  health:
    redis:
      enabled: false
    mail:
      enabled: false
