spring cloud config client not loading configuration from config server

Question

I am following this link: http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html#_client_side_usage

I tested this again and again and not seeing Spring cloud client is loading configuration from cloud server, please help to see where is the error:

POM:

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>

    </dependency>
</dependencies>

Application:

@Configuration
@EnableAutoConfiguration
@RestController
public class ConfigclientApplication {
    
    @Value("${spring.cloud.config.uri}")
    String url;
    
    @Value("${production.host}")
    String host;
    
    
    @RequestMapping("/")
    public String home() {
        return "Host is  => " + this.host ;
    }
    
    public static void main(String[] args) {
        SpringApplication.run(ConfigclientApplication.class, args);
    }
}

bootstrap.properties: spring.cloud.config.uri=http://localhost:8888

The config server is good: http://localhost:8888/spirent/default

{
  "name": "spirent",
  "profiles": [
    "default"
  ],
  "label": "master",
  "propertySources": [
    {
      "name": "classpath:/spirent.yml",
      "source": {
        "production.host": "server1",
        "production.port": 9999,
        "production.value1": 12345,
        "test.host": "server2.com",
        "test.port": 4444,
        "test.value": "hello123"
      }
    }
  ]
}

now http://localhost:8080/ can not be started at all.

Error creating bean with name 'configclientApplication' It seemed the auto inject of @Value can not find the production.host environment value.

How can I read the configuration in client once loaded from config server?

Thanks for your help.

If you are following a tutorial then follow a tutorial. The tutorial mentions that you should use the spring-cloud-starter dependency not the spring-cloud-config-client. For the application it doesn't matter where the configuration comes from, they are just properties which you can access like any other property through the Environment or with @Value. — M. Deinum
I changed to both client or starter, but can not find out configuration value in the config server, any idea? — user3006967
were you able to resolve the issue, the problem I am facing is the properties from config server are begin read from the method if it annotated with @RequestMapping but not otherwise. not sure what can be done in that case. — viveksinghggits

As Deinum implies, I'd ensure you have the client configured with the parent as spring-cloud-starter-parent and give it a version. Maven plugins provided by spring cloud wont work when you include in your dependencies and remember cloud is a different project than boot. Change it to:

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>1.0.0.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

Second, as a new discipline (and likely not your problem here), I'd use the new annotation on your Application instead of @Configuration and @EnableAutoConfiguration

@SpringBootApplication

Third, double check you have @EnableConfigServer on your config server

Fourth, be sure your bootstrap.properties on your client has your spring application name specified:

spring.application.name=spirent

Finally, if you used the spring-cloud-config example project, there is a default user and security password that you have to set in your URI:

http://user:ddf4757e-0077-42e4-b2ad-2ae04340b08c@localhost:8888

Otherwise, try starting from the spring-cloud-config project located here to ensure your config server is setup correctly:
