我从Spring cloud config开始,并以文档中的这个简单示例作为基础:http://cloud.spring.io/spring-cloud-config/single/spring-cloud-config.html#_client_side_usage
当我用作独立的Maven项目时,我的服务器在客户端上也能正常工作
但是我正在一个多模块Maven项目中工作,其中我的根父模块继承自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,我的子模块(例如spring config服务器以及不同的客户端)继承自我的父模块,每个模块都声明了所需的spring boot / cloud依赖关系。
这是麻烦所在,当我从父母那里继承时,客户端配置服务无法再获取配置。这是有关Spring cloud config的说明:
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
所以我的问题是我如何仍可以在Spring Client Config Services中使用Multi Maven模块?是否不直接从spring-boot-starter-parent继承?
在此示例中,我的父服务减少了:

以及我希望如何在子服务中使用:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>spring-cloud-config-client</artifactId>
</dependency>
</dependencies>
</project>
当然,我更改了上面的内容,再次声明了所有依赖项和存储库,它们从spring boot parent继承而来:
2018-12-19 19:14:41.169 INFO 17000 --- [ main] c.c.c.ConfigServicePropertySourceLocator : Fetching config from server at: http://localhost:8888
但是我不认为我应该重新声明所有依赖项,请让我知道是否有人遇到过这种情况。谢谢。
答案 0 :(得分:2)
您仍将需要父级中的Spring Cloud依赖管理部分以及下面的启动项。
<dependencyManagement>
<dependencies>
<dependency>
<!-- Import dependency management from Spring Boot -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.1.1.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
