如何在spring中将maven模块中的所有公共依赖项移到父模块中
如何在spring中将maven模块中的所有公共依赖项移到父模块中
提问于 2017-11-24 17:00:51
我有两个简单的Spring Boot应用程序，一个是eureka-server，另一个是eureka-client。它们都驻留在maven聚合器模块eureka-sample中。
在eureka-server和eureka-client应用程序中，我都有一些共同的依赖项，我希望移到父pom中，这样我就不必时不时地将它们包含在每个子模块中。
我尝试将依赖项spring-boot-starter-test从子模块移到<dependencyManagement>部分下的父pom中，但随后子模块中的测试无法编译，因为这些类无法找到jar。可能是我配置错了，或者放错了。
我怎样才能做到这一点？

尝试将公共依赖项放置在父.pom的.pom部分中，而不是<dependencyManagement>部分中。
使用<dependencyManagement>，您只需要为所有子模块准备和配置依赖项，但是要实际使用它们，仍然需要从子模块中引用它们。
差别是微妙的，但很重要--详细信息请参见https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html。
