Config server client tries localhost:8888 even if URLs are configured

[marnee01]

This seems to have started some time in the past week, but I am not 100% sure. I am testing with by pulling down the "main", building it, installing locally, and using 4.0.0-SNAPSHOT in my local client.

In this scenario, configure one of the following ways:

1. Configure one or more config server URLs under spring.config.import.
2. Or, set up spring.config.import=configserver: without URLs. Set one or more URLs via spring.cloud.config.uri.

Either of the above scenario produces same issue.

Expected: A spring-cloud-config-client will try connecting only to the configured config server URLs.
Observed: The client will try to connect to the default URL "http://localhost:8888" first.

I have attached a sample IntelliJ project that demonstrates the issue. Due to #2051, if you run this as-is, it won't produce a log file, so you can't see the log showing that it is calling localhost. To observe in the logs, update the uri(s) in the application.yml file to point to a real config server and set the application name, password, etc. so that the server will return a 200 and a log will be produced. I will also attach a sample log file.

Note that I was running with Java 17. (Ignore the name of the file in the zipped project that has "Java8".)

@ryanjbaxter Asked me to try 2021.0.1, also. I will see if I can reproduce it that way.

[marnee01]

I switched spring-cloud.version to 2021.0.1 and the issue still presented itself.

I'm also seeing this issue. Did you find any resolution?

[kmartin-bh]

I'm on 2021.0.3. When defining anything other than the default localhost:8888 using spring.config.import, it calls my specified server, then it calls localhost:8888, which fails and the application will not start up.

application.properties:

For reference, I posted this question on SO to try and get some answers. https://stackoverflow.com/questions/73570600/spring-cloud-config-client-tries-localhost8888-in-addition-to-my-specified-serv

[ryanjbaxter]

Can you provide a sample without the AWS pieces that reproduces the issue?

[kmartin-bh]

@ryanjbaxter It's the same example. Using the aws piece or not does not change the behavior.

[kmartin-bh]

I'll remove it and test again, and provide the logs.

[ryanjbaxter]

Please provide a sample zip or git repo not just the logs
