查看异常信息发现这个异常是在初始化事件的时候出现的。

出现这种异常报错一般有几种可能的原因：

1、项目中使用到了连接池，但是没有导入commons.pool.jar包，如果没有导入，导入该包即可解决。commons.pool.jar包下载链接：http://mirrors.tuna.tsinghua.edu.cn/apache//commons/pool/binaries/commons-pool2-2.6.0-bin.zip

2、检查导入的jar包的版本对不对 ，版本不对也会导致这样的问题

3、检查路径是否正确，有些时候applicationContext.xml 这个文件找不到，要放到classes下面。寻找报错的文件的路径与配置信息是否正确

4、最后实在不可以的话可以重新安装tomcat，重新配置一下。
