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);
