以上是异常，自己写的数据库操作，没用框架，只用了Spring

private void init(){

    AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("../config/spring/applicationContext.xml");  
    DataSource ds = (DataSource)ctx.getBean("dataSource");   


    try {

        con =ds.getConnection(); 

    } catch (SQLException e) {

        e.printStackTrace();
    }finally{
        ctx.close();


    }
}

然后是数据库操作，我做了一个查询，没有问题。但是到最后想关闭connection时候报错 的 调用 con.close();

dataresourse用的是org.apache.commons.dbcp.BasicDataSource


配置文件为

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
    destroy-method="close" > 

    <property name="driverClassName" value="${jdbc.driver}" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />

    <property name="maxActive" value="${dbcp.maxActive}" />  
    <property name="maxIdle" value="${dbcp.maxIdle}" />  
    <property name="defaultAutoCommit" value="${dbcp.defaultAutoCommit}" />  

    <property name="timeBetweenEvictionRunsMillis" value="3600000" />  
    <property name="minEvictableIdleTimeMillis" value="3600000" />  
</bean>



求解，，自己瞎写的哈哈
