我的Tomcat 7出现问题。当我尝试通过Eclipse启动应用程序时，Tomcat会抛出异常。应用程序非常简单，它是“Hello World”。

在Tomcat类路径中，我包括：

  

servlet-api.jar org.springframework.web。* org.springframework.orm。*   org.springframework.context。* org.springframework.beans。*

     

在用户条目中bootstrap.jar tools.jar tomcat-jul.jar

有什么问题？

3 个答案:

答案 0 :(得分：2)

您展示的link使用了maven。在这种情况下，错误是您必须在eclipse中将maven依赖项添加到部署程序集。

Right click on your project -> properties -> Deployment Assembly -> Add -> Java Build Path Entries -> Maven dependencies -> Finish.

这应该解决它。

答案 1 :(得分：1)

由于您使用的是Spring，因此错误是由启动Spring应用程序上下文时出现的问题引起的。通常，您只需要查看第一个错误：其他错误是由此引起的。

在您的情况下，由于以下异常，应用程序上下文无法初始化。这意味着Spring应用程序上下文根本无法初始化。

Caused by: java.lang.NullPointerException
at org.springframework.beans.factory.support.DefaultListableBeanFactory.<clinit>(DefaultListableBeanFactory.java:109)

检查您的web.xml文件是否指向正确的Spring配置文件。如果您不确定，请发布文件的相关部分。

答案 2 :(得分：0)

如果您已添加所有必需的jar，则问题可能出在web.xml中。你有ContextLoaderListener吗？换句话说，您可以在Spring上下文中添加XML命名空间，而＃34; HelloWorld＆＃34;则不需要。如果您需要更多帮助，请添加SpringConfig文件和您的web.xml
