我正在开发一个多模块Maven项目，并且我想在Tomcat7中运行我的Web项目，但是出现此错误“启动时子容器失败”。

我继续：（右键单击Web项目）->运行方式->运行配置->目标：tomcat7：run，我有以下日志：

avr。2014年15月5日39:39:23 org.apache.catalina.core.ContainerBase startInternal

）的org.apache.catalina.util.LifecycleBase.start（LifecycleBase.java:150）的org.apache.catalina.core.StandardService.startInternal（StandardService.java:443）。

首先，这是我的父pom.xml：
