Spring Cloud config client not picking values from Config server - spring-cloud

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

Answer 1

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.

Answer 2

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
