Tomcat 在部署过程中遇到的错误，求大神帮忙

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

严重: The web application [/springDemo] 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.

严重: The web application [/springDemo] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@1fa980b]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@113fc37]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

tomcat6 启动无异常。部署时报上述错误 求解答

Answer 1

嗯，看你这程序应该是SSH，建议你检查是否加入了重复的jdbc或者其他jar包。

Answer 2

url="jdbc:mysql://localhost:8080/mylib"
mysql数据库端口默认都是3306，这里是不是有问题？我记得8080是tomcat的吧？

Answer 3

<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
