Maven：Parent Spring Webapp

我想为使用Maven和Spring的所有webapps提供框架基本代码。 Tomcat7在我的子项目上正确启动，但在尝试打开index.html时收到404。Maven：Parent Spring Webapp

符web.xml在父项目（基极）提供。 JSP在子项目中提供。

我猜404是由于POM包装，因为子项目不知道从哪里获得父项目的文件。我错了吗？如何解决它的原因是什么？

编辑是否有可能创建一个父春天web应用程序定义所有的配置文件（web.xml，applicationContext.xml中，servletContext.xml，控制器，...）和儿童项目，其中包含JSP的东西？

看看maven war plugin。这个插件允许它叫做overlays。

覆盖用于跨多个Web应用程序共享公共资源。 WAR项目的依赖关系在WEB-INF/lib中收集，WAR项目自身上覆盖的WAR工件除外。

它可能证明对您和您的要求有用。

这正是我所期待的。十分感谢！ – dtrunk

@dtrunk乐于提供帮助。 –

很好的回答（+1）!!! – Michael

您应该在每个模块中添加依赖关系。最好的做法是在父pom中添加dependencyManagement，并在其中列出与版本，作用域等有关的依赖关系。请注意，父模块根本没有依赖关系元素（因为它只声明依赖关系）
在孩子pom包含不依赖版本，范围等

dependencyManagement父POM：

我可以编译和运行子项目没有任何问题。父项目包含子项目依赖的文件（web.xml，applicationContext.xml，servletContext.xml，tiles.xml）。我不想在每个子项目中添加依赖项。 – dtrunk
