Spring Cloud Config Client tries localhost:8888 in addition to my specified server location

Question

I have only found this issue reported in 1 other place, but no resolution: https://github.com/spring-cloud/spring-cloud-config/issues/2052

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:

spring.application.name=msgw(_)application
spring.config.import=aws-secretsmanager:${ENVIRONMENT}/secret/path,configserver:https://my.server.com
spring.cloud.config.label=${CONFIGURATION_GIT_BRANCH}
spring.cloud.config.username=${username}
spring.cloud.config.password=${password}

Answer 1

Seems my issue was trying to import the aws secret needed to access my server in the same spring.config.import config as my config server. So I'll just need to inject the username password a different way. I thought I tested without both imports, but I had to wipe my target directory and repackage for it to work.

Answer 2

Since some version of Spring Boot (I don't remember exactly, possibly 2.7) the bootstrap.properties mechanism has been deprecated. However to bring back support for this feature a starter has been provided: spring-cloud-starter-bootstrap. This starter causes described behavior and may be the reason as described in:

https://github.com/spring-cloud/spring-cloud-config/issues/2052

Even if not directly added it may be loaded as transient dependency of some other library. One of the examples of such library is log4j-spring-cloud-config-client as described in:
