无法将Spring Boot Admin Server 2和Spring Boot Admin Client 2与Spring Boot 2集成在单个应用程序中

Question

I'm migrating an application from Spring Boot to Spring Boot 2. Previously we had to use Spring Boot Admin Server and Client in a single application (ie the application was both a server and a client at the same). That is weird but we have to continue use it the same way at least for now.

At first I decided to make it work using a demo project: https://github.com/dmitrysenkovich/spring_boot_admin_2_not_working

However, I'm getting an error:

ApplicationRegistrator: Failed to register application as Application(name=spring-boot-admin-sample-servlet, managementUrl=http://localhost:8080/actuator, healthUrl=http://localhost:8080/actuator/health, serviceUrl=http://localhost:8080/actuator/admin) at spring-boot-admin ([http://localhost:8080/instances]): 404 null. Further attempts are logged on DEBUG level

Spring Boot version is 2.0.4.RELEASE and Spring Boot Admin Client/Server is 2.0.2.

Hope one can make it work. Thank you in advance!

Johannes Edmeier (the creator of Spring Boot Admin) answered me on GitHub here: https://github.com/codecentric/spring-boot-admin/issues/889 .

If you set the spring.boot.admin.context-path, you also have to include this suffix in the spring.boot.admin.client.url

It works!
