在 Eclipse 的 Java EE 项目中启动 tomcat 7.0 时遇到了一些问题。启动服务器时出现超时错误。我不知道出了什么问题。我尝试将超时限制增加到 1800 秒，但它没有改变任何东西。

以下是tomcat尝试启动时的日志：

信息：服务器在 1846 毫秒内启动

具体来说，作为应用服务器的 Tomcat 已成功启动（如堆栈跟踪中的最后一行所示test）正如您从

无法启动组件 [StandardEngine[Catalina].StandardHost[localhost] .StandardContext[/test]] 原因：java.lang.NoClassDefFoundError: Lorg/apache/commons/logging/Log;

从这里下载缺少的依赖项

为避免将来出现麻烦，请复制您从上面的链接下载的公共库 jar，并将它们放在部署包的文件WEB-INF\lib夹（文件夹或 .war 文件）中。test

或者，

从此处的 Commons 站点下载并安装 Apache Commons Logging 库的最新副本，然后复制到TOMCAT_HOME\common\lib文件夹中（如果路径不存在，请创建路径）。TOMCAT_HOME指的是你的tomcat安装文件夹。不要将jar复制到多个位置，这会导致以后出现问题

由于缺少已安装的 Web 应用程序的依赖项，Tomcat 无法启动。从您的堆栈跟踪中（消除嗡嗡声：P）

...[blah blah]...
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.Log

尝试删除所有已部署的 Web 应用程序，然后重新开始。如果 Tomcat 将启动，那么您可以尝试找出您的 Web 应用程序是什么导致了所有这些混乱。
