How to Deploy Maven project on tomcat in eclipse SEVERE: A child container failed during start java.util.concurrent.ExecutionException

您好，我是 Maven 新手，刚刚从 SVN 存储库中下载了一个项目，它在上次恢复期间处于良好的工作状态。它使用spring + hibernate + jsf，并且正在部署在tomcat服务器上。我收到以下错误，不确定问题出在哪里，我很迷茫。任何方向都将不胜感激！

再次提前感谢！

编辑：

已解决：

这对其他人可能有用也可能没有用，但请记住，我是 Maven 新手，结果发现我在部署程序集中缺少 Maven 依赖项。

这是通过右键单击 Eclipse 中的项目添加的。

->Properties -> Deployment Assembly -> Add --> 然后选择 Maven Dependencies。

【问题讨论】：

  • 我正在使用最新版本的 Eclipse IDE for Java EE Developers, (Juno)
  • 在Eclipse你用过Run as -> Run on server吗？
  • 是的，我以前用过这个，我忘记了在部署程序集中添加 Maven 依赖项。

标签： eclipse spring tomcat maven deployment


【解决方案1】：

您可能需要尝试在 Eclipse 中刷新所有项目。之后，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。

【讨论】：

  • 感谢您的回复！我忘记了在部署程序集中添加 Maven 依赖项。
  • 通常也会这样做。 :)
【解决方案2】：

加载 Springs jar 文件失败。

第一种方法：

  • 确保您已安装 m2eclipse 插件
  • 将项目导入为maven project
  • 将项目方面更改为Dynamic web project
  • Add maven dependency for deployment
  • 现在应该开始使用Run as -> Run on server

第二种方法：

如果上述方法不起作用，则必须更改 tomcat 的server.xml。将其指向target`s snapshot folder。如下所示

<Context
  docBase="/path/to/target/cepis/snapshot/folder" 
  path="/cepis"
  reloadable="true" />

代替

<Context
  docBase="cepis"
  path="/cepis"
  reloadable="true"
  source="org.eclipse.jst.jee.server:cepis"/>

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。

【讨论】：

  • 感谢您的回复！我已经完成了上述“第一种方法”项目，我忘记的是在部署程序集中添加 Maven 依赖项。
  • 是的，更新了答案，虽然是你指出的；）
