mysql - 在 tomcat7 中部署 Web 应用程序

Question

我已经在 tomcat7 中部署了一个网络应用程序，我所要做的就是启动该应用程序，但每次我尝试启动该网络应用程序时，我总是会遇到此错误:

FAIL - Application at context path /agileexpress could not be started

这是我在日志中得到的，好像我的 sql 有问题

May 15, 2015 4:54:55 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 35067 ms

SEVERE: Error listenerStart

SEVERE: The web application [/agileexpress] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

SEVERE: The web application [/agileexpress] appears to have started a thread named [MySQL Statement Cancellation Timer] but has failed to stop it. This is very likely to create a memory leak.

谁能帮帮我？我是 tomcat7 的新手

将您的 JDBC 驱动程序移动到 Tomcat(通用类加载器)lib/目录(在 catalina.properties 文件中定义，通常位于 CATALINA_HOME/lib 中)。这将告诉通用类加载器加载驱动程序，您的 webapp 类加载器应该没有问题。
