Spring Cloud config client not picking values from Config server

My Config client is not picking the property values from config server.

http://localhost:8888/customer_service/default

Above Config server endpoint is returning proper values for Config client,

{
    "name": "customer_service",
    "profiles": [
        "default"
    ],
    "label": null,
    "version": "c7648db5662dc65aeaad9c91abbf58b41010be7c",
    "state": null,
    "propertySources": [
        {
            "name": "https://github.com/prasadrpm/MicroService_config.git/customer_service.properties",
            "source": {
                "customer.config.location": "XXXX",
                "customer.config.name": "YYYY"
            }
        }
    ]
}

Solution

  • The URL that returns you correct properties/configuration is: localhost:8888/customer_service/default

    Client application is querying for properties based on following data:

    c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at : http://localhost:8888
c.c.c.ConfigServicePropertySourceLocator : Located environment: name=config_server, profiles=[default], label=null, version=c7648db5662dc65aeaad9c91abbf58b41010be7c, state=null
b.c.PropertySourceBootstrapConfiguration : Located property source: [BootstrapPropertySource {name='bootstrapProperties-configClient'}]
com.customer.CustomerServiceApplication  : No active profile set, falling back to default profiles: default
...

    So, effectively, client application is calling:

    localhost:8888/config_server/default

    So, there are two solutions:
