Los microservicios tomas sus configuraciónes de la estructura de su proyecto, esto es src/main/resource en los archivos application.properties. Pero esto puede delegarse a un servidor el cual tendra esta estructura en una ruta del proyecto se servidor de configuracion sea /src/main/resource/common-config la cual se puede configurar en el pom del proyecto.
<resources>
<resource>
<filtering>true</filtering>
<directory>src/main/resources</directory>
<includes>
<include>*.properties</include>
<include>common-config</include>
</includes>
</resource>
</resources>
El archivo de configuración application.properties de server config tendrá
spring.profiles.active=native
server.port=8888
spring.cloud.config.server.native.search-locations=classpath:/common-config
En el directorio /common-config se tiene el archivo de configuración que tomara el productor
application.properties y tendra
eureka.client.serviceUrl.defaultZone=http://localhost:8090/eureka
En la aplicación del server de configuración se usa la anotación @EnableConfigServer
Para verificar el server config en runtime podemos consultar por http://localhost:8888/application/default
Ahora tenemos que decirle al Productor que ya no tome su configuración de sus recursos /src/main/resources/application.properties, comentamos la linea que le indica donde esta el eureka server ya que esta la tomara del server config.
En el Productor debemos agregar la dependencia
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
Ahora solo arancamos en orden
1.- employee-config-server
2.- eureka-server
3.- employee-producer
y observamos en la página de eureka que el productor se puede registrar.
Al ejecutar el Productor obtendrá su configuracion del servidor http://localhost:8888.
