<!-- 1 配置注解的自动扫描-->
<context:component-scan base-package="cn.itcast.crm"/>


<!-- 2 配置数据源 -->

<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/itcast0807crm?useUnicode=true&characterEncoding=GBK"/>

<!--连接池中保留的最小连接数。-->
<property name="minPoolSize" value="5" />

<!--连接池中保留的最大连接数。Default: 15 -->
<property name="maxPoolSize" value="30" />

<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->

目测是C3P0链接池的问题, mysql的8小时的问题 , http://www.iteye.com/problems/100148

遇到同样的问题了，原因是自己写con.prepareCall(updateTABLE); 不小心写成了con.prepareCall(”updateTABLE“);
