IntelliJ IDEA 16将maven依赖项添加到classpath

Question

我是IntelliJ的新手并使用2016.2版本.以前我在使用Eclipse.我正在尝试建立一个简单的maven spring测试项目,但是我无法弄清楚出了什么问题.

注意:我知道异常意味着什么,并且我知道使用Eclipse的解决方案

注2:我尝试了一个干净的Idea安装

根据我的理解,想法将自动包括maven依赖(如果我错了,请纠正我)

编辑1: 解决方案

1. 项目 - >右键单击 - >添加框架支持 - >检查Spring/Spring MVC
2. 加 <packaging>war</packaging>
3. 重新导入maven依赖项

我试图做什么

1. 重新导入maven依赖项
2. 关闭IntelliJ并删除所有*.iml文件和所有.idea文件夹

例外

java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

是的,如果Auto Import在提示时检入,则在您打开IntelliJ时单击.

如果没有,请点击Maven ProjectsIntellij的右侧窗格,然后在refresh- > 后单击按钮Generate sources and auto import.这会再次触发该过程.

如果以上操作无效并且您仍然遇到IDE问题,请转到File -> Invalidate Cache/Restart选项.提示如下.

单击Invalidate and restart,这将重新索引所有依赖项到工作区.
