Admin Server启动类

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

application.yml配置

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

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
