我正在努力让一个示例应用程序为我自己工作，因为我刚刚开始使用Spring Boot。我创建了我的restful服务，下一步是运行配置服务器，以便我可以动态刷新属性。但是我的配置服务器似乎没有加载属性。所以我有以下设置：
配置服务器/pom.xml

在src / main / resources中我有一个config目录，里面有一个hello-service.properties文件，其中包含以下内容：
very-so-much=testing
配置服务器启动正常，并在日志显示

我还有一个spring boot restful服务，我想加载配置服务器维护的属性。宁静的申请如下：

我的hello-service / app.class - 为了清晰起见，提供了一些代码
@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("${very-so-much}") String exclamations) {
CustomerProps p = new CustomerProps();
p.setText(exclamations);
return p;
}
hello-service / restful service我尝试加载属性omiited代码以保持清晰
@RestController
@RequestMapping("/customer")
public class GreetingController {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
//TODO switch to autowired annotation
private CustomerRepository repository;
private final GridFsTemplate fs;
private CustomerProps props;
@Autowired
public GreetingController(CustomerRepository repository, GridFsTemplate gridFileSystem, CustomerProps props) {
this.repository = repository;
this.fs = gridFileSystem;
this.props = props;
}
@RequestMapping("/greeting")
public Greeting greeting(@RequestParam(value="name", defaultValue="World") String name) {
name = props.getText();
return new Greeting(counter.incrementAndGet(),
String.format(template, name));
}
我的application.properties
server.port=${PORT:9001}
spring.profiles.active=native
bootstrap.properties
spring.application.name=hello-service
spring.cloud.config.uri=http://localhost:8889
因此，当我点击restful endpoint问候语时，它会抛出异常，如下所示
2015-10-19 15:21:41.292 INFO 8140 --- [nio-9001-exec-1] o.s.web.servlet.DispatcherServlet : FrameworkServlet 'dispatcherServlet': initialization started

任何关于我在这里缺少什么的想法。我试图发布尽可能多的信息，但如果您需要任何进一步的信息，请询问。感谢
答案 0 :(得分：1)
spring.application.name=hello-service需要进入bootstrap.properties（bootstrap not Bootstrap）。否则，configserver不知道要抓取哪个配置。
