无法解析值"${zuul.prefix}“中的占位符'zuul.prefix‘

Question

我有一个项目，微服务的网关-服务器(Zuul)，eureka-服务器与配置服务器的集成.

我有一个git存储库，它具有网关服务器的属性文件(gateway-server-dev.yml)。

网关-服务器-dev.yml文件：

    spring:
    application:
    name: gateway-server

 info:
  component: Gateway Server

endpoints:
 restart:
   enabled: true
 shutdown:
enabled: true
 health:
   sensitive: false



  zuul:
 prefix: /CustomerHub/api
 routes:
   create-customer: 
      path: /create/**
     serviceId: create-customer
   search-customer: 
     path: /search/**
     serviceId: search-customer
   update: 
      path: /update/**
     serviceId: update-customer
   authorization:
     path: /authorization/**
     sensitiveHeaders:
     serviceId: customerhub-authorization      
  host:
       connect-timeout-millis: 5000
       socket-timeout-millis: 10000
        max-total-connections: 10000
       max-per-route-connections: 50
 ribbon:
   eager-load:
     enabled: true

   ribbon:
 ReadTimeout: 60000
 ConnectTimeout: 60000
 MaxAutoRetries: 3
 MaxAutoRetriesNextServer: 3
 restclient:
 enabled: true
      eureka:
       enabled: true



eureka:
  client:
    serviceUrl:
      defaultZone: http://{host}:{port}/eureka
    registerWithEureka: true
  instance:
    preferIpAddress: true  

hystrix:
  threadpool:
    default:
      coreSize: 1000
      maximumSize: 10000
       queueSizeRejectionThreshold: -1
     maxQueueSize: -1
  command:
    default:
      execution:
        isolation:
          strategy: THREAD
         thread:
              timeoutInMilliseconds: 60000

server:
  port: 9000


logging:
  file: /app/logs/aaa_gateway.log
  level:
    org.springframework.web: INFO
    com.customerhub.filters: INFO
    org.hibernate: INFO

customerhub:
  authorization:
    check-token-url: /oauth/check_token   

网关服务器中的引导文件是：

spring.profiles.active=dev
spring.application.name=gateway-server
spring.cloud.config.uri=http://{host}:{port}
management.security.enabled=false
management.endpoints.web.exposure.include=*

现在，当我在本地系统中在eclipse中执行时，它工作正常，并从配置服务器获取属性。

当我通过命令提示符运行同一个jar时，它会给出以下错误：

无法解析值"${zuul.prefix}“中的占位符'zuul.prefix‘

日志文件是：

Spring无法找到gateway-server-dev.yml文件，所以使用下面的代码将yml文件添加到类路径中。

@PropertySource("classpath:gateway-server-dev.yml")

或将这些行添加到节下的pom中。

<resource>
     <directory>src/main/resources</directory>
     <filtering>true</filtering>
     <includes>
          <include>**/*.yml</include>
     </includes>
</resource>
