春天配置服務器不加載本機屬性

我想爲我自己創建一個示例應用程序，因爲我剛開始玩弄Spring Boot。我創建了我的寧靜服務，下一步是讓配置服務器運行，以便我可以動態刷新這些屬性。但是我的配置服務器似乎沒有加載屬性。所以，我有以下設置：春天配置服務器不加載本機屬性

配置服務器/pom.xml

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      <artifactId>spring-cloud-config-server</artifactId> 
     </dependency> 

    </dependencies> 
</project>

配置，服務器/應用類

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 
import org.springframework.cloud.config.server.EnableConfigServer; 
import org.springframework.context.annotation.Configuration; 

@Configuration 
@EnableAutoConfiguration 
@EnableConfigServer 
public class ConfigurationServerApplication { 

    public static void main(String[] args) throws Exception { 
     SpringApplication.run(ConfigurationServerApplication.class, args); 
    } 
}

配置服務器/application.yml

server: 
    port: ${PORT:8889} 
logging: 
    levels: 
    org.springframework.boot.env.PropertySourcesLoader: TRACE 
    org.springframework.web: DEBUG

#conf: /Users/jlong/work/bootiful/bootiful-microservices/code/spring-doge-microservice-configuration 



#my: 
# property:******************myvalue***************************

在src/main/resources中我有一個config目錄，裏面有一個hello-service.properties文件，翼：

very-so-much=testing

在配置服務器啓動了罰款，並偵聽端口8889的日誌顯示

我也有春天開機寧靜的服務，我想加載由保留的屬性配置服務器。 REST風格的應用程序如下：

我打招呼服務/ app.class --ommited爲清楚起見

@SpringBootApplication 
public class Application implements CommandLineRunner { 

    @Autowired 
    private CustomerRepository repository; 

    public static void main(String[] args) { 
     SpringApplication.run(Application.class, args); 
    } 

    @Bean 
    @RefreshScope 
    CustomerProps customerProps(@Value("${very-so-much}") String exclamations) { 
     CustomerProps p = new CustomerProps(); 
     p.setText(exclamations); 
     return p; 
    }

你好服務一些代碼/寧靜服務，我嘗試加載屬性omiited代碼清晰

@RestController 
@RequestMapping("/customer") 
public class GreetingController { 

    private static final String template = "Hello, %s!"; 
    private final AtomicLong counter = new AtomicLong(); 

    //TODO switch to autowired annotation 
    private CustomerRepository repository; 
    private final GridFsTemplate fs; 
    private CustomerProps props; 

    @Autowired 
    public GreetingController(CustomerRepository repository, GridFsTemplate gridFileSystem, CustomerProps props) { 
     this.repository = repository; 
     this.fs = gridFileSystem; 
     this.props = props; 
    } 

    @RequestMapping("/greeting") 
    public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) { 
     name = props.getText(); 
     return new Greeting(counter.incrementAndGet(), 
          String.format(template, name)); 
    }

而我的application.properties

個 
server.port=${PORT:9001}  
spring.profiles.active=native

bootstrap.properties

spring.application.name=hello-service 
spring.cloud.config.uri=http://localhost:8889

所以，當我打的寧靜終點迎接它拋出異常，如下

任何人什麼，我在這裏失蹤的任何想法。我試圖發佈儘可能多的信息，但如果您需要更多信息，請詢問。由於

spring.application.name=hello-service需要bootstrap.properties去（引導自引導不）。否則，configserver不知道要抓取哪個配置。

對bootstrap.properties進行了更改，但仍得到相同的錯誤。如何檢查我的hello-service.properties文件是否已被服務器加載？ – user1107753

好吧有點奇怪現在似乎工作。在將應用程序名稱添加到引導程序之後，也只是直接向控制器添加屬性，如@Value（「$ {very-so-much}」） private String prop; – user1107753
