Maven WAR Build for Tomcat：“无法打开ServletContext资源”
关于这个话题已经有一些问题了，但是我的Tomcat运行还不顺畅。
我的工作空间包括jsf和spring。 只要我在Eclipse中构build和运行locale中的项目并将其部署到Eclipse中的Tomcat中，一切都运行良好。 但是现在我想将war文件部署到外部Tomcat中，在我的情况下是Docker-Container中的Tomcat。
所以我做的是：
*使用以下Maven-pom（摘录）构buildWAR文件。
*并将战争文件复制到我的正在运行的容器，如下所示：
docker cp projectName.war containerID：/ usr / local / tomcat / webapps /
在Tomcat启动期间，我总是得到以下错误。
一开始，我已经将applicationContext.xml文件直接放在WEB-INF文件夹中。 但是我知道在“\ WEB-INF \ classes”中使用它会更好，所以我将它移动到那里，并在web.xml中执行了以下context-Location-parameter。
所以工作空间的Hierarchy看起来像下面的图片projectName
| – 网页内容
| – WEB-INF
| – pom.xml
另一件事是，当我在构build之后提取war文件以查看applicationContext.xml文件的实际位置时，我在“\ WEB-INF \ classes”中find了它，但是在web中的context-Location-parameter .xml缺lessfind它。 我也试着把applicationContext.xml -File的副本放到src / main / resources中 ，这导致，这个文件位于WAR文件的正确位置，但web.xml改变了。
有人build议在何处放置applicationContext.xml文件，以及如何在构build过程中包含和指向正确的方法。 此外，为什么web.xml在构build过程中发生变化。 还是有一个完全不同的问题？
感谢帮助。

工作区的层次结构
过了一会儿，我做了。
- “maven clean”是因为一些依赖关系老旧无效。 这就是为什么web.xml在构build过程中没有更改
- JSF依赖关系是需要的，所以没有更多的“提供”
- Docker容器有一个JDK 7，但我的应用程序是用JDK 8构build的，所以我将容器更改为一个带有JDK 8的Tomcat 8
- 需要告诉Maven-Build web.xml文件在哪里，哪些文件应该包含在WAR-Build中。 我用下面的Maven-Plugin做了这个：（也不要忘了添加Maven Dependencies到Eclipse中的部署程序集）
