Spring Cloud config client not picking values from Config server

Question

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"
            }
        }
    ]
}

Config client bootstrap.properties

server.port=8080
spring.application.name=customer_service

spring.cloud.config.enabled=true
spring.cloud.config.name=config_server
spring.cloud.config.uri=http://localhost:8888

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:

delete spring.cloud.config.name=config_server property in bootstrap.properties, and your application should be able to fetch properties.
update value of spring.cloud.config.name to customer_service service. But if you do not provide spring.cloud.config.name explicitly, then client will use spring.application.name as the default value for spring.cloud.config.name.

What annotation you had used here? It can be easily retrieved like this.

@Value("${customer.config.location}")
    private String someOtherProperty;

and it is not needed

spring.cloud.config.name=config_server
