У меня проблемы с созданием приложения Spring Boot + Spring Cloud, которое объединяет Zuul, сервер Eureka, сервер Config и сервер Admin в одно уникальное приложение.
Если вы уже думаете: «Почему, черт возьми,это нарушает концепции микро-услуг и т. д. "Я полностью согласен.Этот вопрос касается возможности сделать это, а не спрашивать, если это хорошая идея, спасибо за ваше понимание.
Кто-нибудь знает, как это сделать?Будет неплохо какое-то решение с Spring 2.1.0 + Spring Cloud Finchley или выше.
Код, очевидно, очень прост:
`
@EnableZuulProxy
@EnableAdminServer
@EnableConfigServer
@EnableEurekaServer
@SpringBootApplication
public class Main {
public static void main(String[] args) {
SpringApplication.run(Main.class, args);
}
}
`
Пом также прост:

<version>2.1.0.RELEASE</version>
<relativePath/>

С также простым файлом конфигурации:
spring.application.name=question
server.port=8090
eureka.client.service-url.defaultZone=http://localhost:8090/eureka
spring.boot.admin.context-path=/admin
spring.cloud.config.server.prefix=/config
spring.cloud.config.server.git.uri=...
spring.cloud.config.server.git.searchPaths=...
[...]
Ближайшее, что я получил, былоиспользовать 2.0.6 + Финчли:
