Я разрабатываю Spring Boot + Microservices пример.Я взял ссылку по ссылке: https://github.com/PacktPublishing/Mastering-Spring-Cloud/tree/master/Chapter06/sample-spring-cloud-comm-feign.

В этом примере я могу успешно запустить discovery-service и gateway-service, но при попытке запустить любой другой сервис я получаю нижеошибка.

Одна вещь, которую я заметил, что инструкции не очень ясны о том, как выполнить код, даже не упомянутые ясно в книге.Пожалуйста, руководство. 

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.
19:05:25.564 ERROR 

***************************
APPLICATION FAILED TO START

Description:

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

Измените порт в application.yml, где у вас есть свойства ниже.В вашей системе tomcat, вероятно, работает через порт 8080 по умолчанию.

сервер:
порт: $ {PORT: 8080}

Надеюсь, что указанное выше изменение может вам помочь.
