java - 错误 - 在 tomcat 7.0 (windows) 中部署 war 文件

Question

在Tomcat服务器中部署war文件时出现以下错误

我执行了以下步骤，

1) 下载 Apache Tomcat Zip

2)解压到D盘

3) 添加了 JAVA_HOME,JRE_HOME,CATALINA_HOME 环境变量

4)启动Tomcat服务器startup.bat(服务器启动成功)

5)添加了一个war文件，该文件是从eclipse中的maven项目创建的

6) 服务器开始部署war文件

7) 部署后出现以下错误

尝试从 Eclipse 运行此命令 - 添加服务器选项(创建相同的错误集)

堆栈跟踪中的错误似乎指向未找到的类(由:java.lang.NoClassDefFoundError:Lorg/apache/commons/logging/Log;)引起。这让我猜测应用程序中的某个地方缺少依赖项。您可以尝试下载 commons-logging 并将它们作为打包的一部分包含在您的 war 文件中，或者将 jar 包含在 tomcat 中以查看错误是否消失。您还可以查看此问题上类似错误的答案。 Tomcat doesn't start on eclipse
