如何在 eclipse 中的 tomcat 上部署 Maven 项目严重：启动时子容器失败 java.util.concurrent.ExecutionException
Hello I am new to Maven and just pulled down a project from an SVN repository, it was in a good working state during its last reversion. It is using spring + hibernate + jsf, and is being deployed on a tomcat server. I am getting the following error and was not sure what the problem is and am very lost. Any direction at all would be GREATLY appreciated!

This may or may not be useful to others, but keep in mind I am new to Maven, turns out I was missing Maven Dependencies in the Deployment Assembly.
这对其他人可能有用也可能没有用，但请记住，我是 Maven 的新手，结果我在部署程序集中缺少 Maven 依赖项。
This was added by right clicking on the project in Eclipse.
这是通过右键单击 Eclipse 中的项目添加的。
->Properties -> Deployment Assembly -> Add --> and then selected Maven Dependencies.
->Properties -> Deployment Assembly -> Add --> 然后选择Maven Dependencies。

It is failing to load Springs jar files.
无法加载 Springs jar 文件。
First approach:
第一种方法：
- Make sure you have
m2eclipseplugin installed - Import the project as
maven project - Change projects facet to
Dynamic web project - Add maven dependency for deployment
- Now it should start using
Run as -> Run on server
- 确保你安装了
m2eclipse插件 - 将项目导入为
maven project - 将项目方面更改为
Dynamic web project - 为部署添加 maven 依赖
- 现在它应该开始使用
Run as -> Run on server
Second approach:
第二种方法：
If above does not work, you will have to change server.xmlof tomcat. Point it to target`s snapshot folder. It will be something like below
如果以上不起作用，您将不得不更改server.xmltomcat。将其指向target`s snapshot folder。它会像下面这样
<Context
docBase="/path/to/target/cepis/snapshot/folder"
path="/cepis"
reloadable="true" />
Instead of
代替
<Context
docBase="cepis"
path="/cepis"
reloadable="true"
source="org.eclipse.jst.jee.server:cepis"/>
Now just start tomcat from eclipse. This approach always works for any web application.
现在只需从 eclipse 启动 tomcat。这种方法始终适用于任何 Web 应用程序。

You might need to try refreshing all of your projects in Eclipse. After that, make sure you "clean" the server state before starting it. If its throwing NoClassDefFound errors, from my experience that means it can't find the files it needs.
您可能需要尝试在 Eclipse 中刷新所有项目。之后，请确保在启动之前“清理”服务器状态。如果它抛出 NoClassDefFound 错误，根据我的经验，这意味着它找不到它需要的文件。
