应用程序注册了JDBC驱动，但当程序停止时无法注销这个驱动，tomcat为了防止内存溢出，就给强制注销了

 

解决：

重写了org.apache.commons.dbcp.BasicDataSource  的 close（）方法：

 

package org.company.util;

import java.sql.DriverManager;

import java.sql.SQLException;

import org.apache.commons.dbcp.BasicDataSource;

public class XBasicDataSource extends BasicDataSource{

 @Override  public synchronized void close() throws SQLException{ //  System.out.println("......输出数据源Driver的url："+DriverManager.getDriver(url));   DriverManager.deregisterDriver(DriverManager.getDriver(url));   super.close();  } }

。。。

 

在dbcp数据源中的配置：

  class="org.company.util.XBasicDataSource" destroy-method="close">       value="oracle.jdbc.driver.OracleDriver">          value="jdbc:oracle:thin:@XX.XXX.XX.X:1521:ccdb">   

 

问题解决~

再重新加载的时候发现还有：

严重: The web application [/codeMarket] registered the JBDC 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.

检查了一下jar包  发现多了一个mysql-connector-java-bin.jar   赶紧删之   ok~
