[英]Spring cloud config cloud without inheriting from parent
我從Spring cloud config開始,並以文檔中的這個簡單示例作為基礎: http : //cloud.spring.io/spring-cloud-config/single/spring-cloud-config.html#_client_side_usage
當我用作獨立的Maven項目時,我的服務器在客戶端上也能正常工作
但是我正在一個多模塊Maven項目中工作,其中我的根父模塊繼承自spring boot:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
因此,我的子模塊(例如spring config服務器以及不同的客戶端)繼承自我的父模塊,每個模塊都聲明了所需的spring boot / cloud依賴關系。
這是麻煩所在,當我從父母那里繼承時,客戶端配置服務無法再獲取配置。 這是關於spring cloud config的解釋:
To use these features in an application, you can build it as a Spring Boot application that depends on spring-cloud-config-client (for an example, see the test cases for the config-client or the sample application). The most convenient way to add the dependency is with a Spring Boot starter org.springframework.cloud:spring-cloud-starter-config. There is also a parent pom and BOM (spring-cloud-starter-parent) for Maven users and a Spring IO version management properties file for Gradle and Spring CLI users
所以我的問題是我如何仍然可以在Spring Client Config Services中使用multi Maven模塊? 是否不直接從spring-boot-starter-parent繼承?
在此示例中,我的父服務減少了:

以及我希望如何在兒童服務中使用:

當然,我更改了上面的內容,再次聲明了所有依賴項和存儲庫,並從spring boot parent繼承而來:
2018-12-19 19:14:41.169 INFO 17000 --- [ main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at: http://localhost:8888
但是我不認為我應該重新聲明所有依賴關系,請讓我知道是否有人遇到過這種情況。 謝謝。
從文檔中 :
在父級中,您仍然需要Spring Cloud依賴關系管理部分,在下面,還有一個引導。
