application.properties

server.port = 9090
spring.application.name = adminserver

DemoApplication.java

@SpringBootApplication
@EnableAdminServer
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

这很有效。我可以导航到 http://localhost:9090/#/applications 看到管理服务器就好了。

问题是当我尝试将一个客户端应用程序注册到服务器时。以下是我的客户端应用程序的详细信息:

        <artifactId>spring-boot-admin-starter-client</artifactId>
        <version>1.5.7</version>
    </dependency>
</dependencies>

application.yml

spring:
  profiles: default
  boot:
    admin:
      url: http://localhost:9090
management:
  context-path: /actuator

http://localhost:8081/actuator/health 并查看所有的健康信息。但我最终在控制台中也会出现以下错误:

DEBUG --- [   registrationTask1] de.codecentric.boot.admin.client.registration.ApplicationRegistrator                       : Failed to register application as Application [name=ClientApp, managementUrl=http://richard-desktop:8081/actuator/, healthUrl=http://richard-desktop:8081/actuator/health/, serviceUrl=http://richard-desktop:8081/] at spring-boot-admin ([http://localhost:9090/api/applications]): 404 Not Found

我做错了什么?

基本上,由于SpringBootAdminServer(2.1.0)和客户端(1.5.7)的版本不同,它无法注册。

只需在调试日志中启动服务器/客户机,就可以获得关于它试图访问哪个url的更多提示。

这里需要注意的是,由于许多端点的版本不可编译性,我们不会获得所有信息。执行器模块在1.X和2.X之间完全改变。

根据以上观点,以下是解决此问题的方法,但有一些限制:

客户端Java文件:

@SpringBootApplication
public class ClientApplication {

    public static void main(String[] args) {
        SpringApplication.run(ClientApplication.class, args);
    }
}

客户端属性文件:

server.port=8081
spring.boot.admin.url=http://localhost:8080
spring.boot.admin.api-path=/instances
management.security.enabled=false
