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

1. 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"       }     }   ] } 

2. 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 using 2020.0.0 version of spring cloud than you need to this dependency in your maven dependencies to enable bootstrap, which is desabled by default in 2020.0.0.

Breaking changes in 2020.0.0

It work for me.

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