Tomcat报错: JDBC unregister 解决办法

 Tomcat报错: JDBC unregister 解决办法

摘要: The web application [web application] registered the JDBC driver [net.sourceforge.jtds.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.

tomcat6关闭时触发日志提示:

The web application [web application] registered the JDBC driver [net.sourceforge.jtds.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.

原因是tomcat6最新版本引入内存溢出检测阻止机制,检测到jdbc在tomcat运行时进行注册,但是当tomcat停止时没有解除注册。

有两个方法可以解决这个问题:

    1、显式的解除注册

// Example: DriverManager.getDriver("jdbc:mysql://localhost:3306");
java.sql.Driver mySqlDriver = DriverManager.getDriver("YOUR DRIVER");
DriverManager.deregisterDriver(mySqlDriver);

    2、使用tomcat jdbc连接池,并将jdbc驱动包拷贝至tomcat的lib下,由tomcat自己进行管理。
