首页一访问，Tomcat就报错， 自动stop ， 然后就退出了cmd窗口

[R1310328554]

redis 也配置好了，数据库也初始化了，启动也是没问题的。应用直接部署在ROOT下。但是，浏览器访问 http://localhost:8080/ 的时候， Tomcat就出错， 然后自动stop 了， 好奇怪啊。 有谁遇到过吗？ 或者我配置哪里错了？

首先这个错误，我初步判断，和这个项目无关系，应该是环境问题，线程之类的有冲突。请按第一个异常信息“The web application [] registered the JDBC driver [com.alibaba.druid.proxy.DruidDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.”
进行寻找答案。

建议查看Tomcat里是否有其他项目干扰。还有可能是Tomcat已经损坏，请尝试更换Tomcat。

今天一直在忙，现在才回复，抱歉！

应该就是Tomcat的环境问题，不过，具体原因未找到。 我通过mvn 方式， maven-jetty-plugin 插件 的jetty run 启动项目就没这个问题。
