最近在搭建项目，遇到启动Tomcat时 遇到如下问题：

严重: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener

具体异常如下：

问题分析： 这是你的jar文件没有同步发布到自己项目的lib目录中

解决办法：项目点击右键 点击 Properties 选择Deployment Assembly 再点击右边的Add按钮 选择Java Build Path Entries后点击Next按钮 然后选择你的Maven Dependencies 确定即可
