But when i am running the app, it builds but i am getting the following warning. Anybody has any idea what i am not doing right?

Fetching config from server at: http://localhost:8888
2018-01-31 16:41:54.818  WARN 10760 --- [on(2)-127.0.0.1] c.c.c.ConfigServicePropertySourceLocator : Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/application/default": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect

Answer 1

See resolution here (Spring Cloud Config Server Can't locate PropertySource on startup) from Dave Syer

If your config server is not intended to be a config client as well you need to set spring.cloud.config.enabled=false to avoid that log entry (it's harmless though).

Answer 2

This error is shown when one of your services is not able to connect to the cloud-config server.

In order to make it work:

Assuming that you are using STS or any Eclipse environment, run your cloud-config server application and then run the other service whose configurations are stored at the cloud-config.

It is very important to keep running both the services.

Other precautions that need to be taken care of are:

• Your application's application.properties file should be renamed to bootstrap.properties
• The port should not be used by any other services
