Issue
Config Client is not working in Spring boot
I was trying out config server client in Spring boot and came across this weird issue.
I have been able to successfully spin up the config server up and running but while trying to start the config client/consumer, it seems like the client isn't fetching any information from the config server.
Output while running client:

Reason: Failed to determine a suitable driver class

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

spring:

Have not included any application.yml file for config-client.
My config server is up on port 8181 and i am able to fetch the config from github successfully,
Sample success response:

}
}
]
}
I know there must be some key/value errors in the files above, i'll manage that but only given that my config-client starts fetching config from my config-server running successfully. There is no security in my config-server so i won't need username, password.

PS: I have tried debugging this a lot over other stackoverflow questions and official docs on internet, but nothing seems to be fixing my issue. Initially i thought that my bootstrap.yml file must not be loading for some reasons, but now i am feeling that the config isn't working for my client at all because in the startup log it is mentioned that configuration from specific config-server-name/link:port was being tried to be fetched. Also, please ignore the errors in my grammar :)
Solution
2020.0.0 Spring Cloud Config does not support bootstrap file.
For a workaround use bootstrap.{yml|properties} and add a dependency on spring-cloud-starter-bootstrap to restore the old behavior.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>
