访问 Web 应用程序包中的 Spring 配置文件

Question

我很难让 Spring 项目在 Virgo 3.0.2 上运行，更准确地说是读取 applicationContext 文件，这是我的 StackTrace：

如果需要，我已准备好提供完整的项目，我尝试了各种 配置，总是遇到同样的问题。 非常感谢。

问题是：

ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

您的应用程序没有导入这个包，并且类加载器找不到这个类，要解决这个问题，您需要在清单中添加 import 语句：

导入包：org.springframework.web.context;version="[3.0.5.RELEASE,3.0.5.RELEASE]"

可能还有其他你在 web.xml 中使用的，例如：

org.eclipse.virgo.web.dm
org.springframework.web.servlet
org.springframework.osgi.web.context.support
