这是我从家里拿来的可用的项目，在家里是可以运行的。
今天放在别的机器上，同样配置就出现了如下异常：
** BEGIN NESTED EXCEPTION **

java.net.SocketException
MESSAGE: java.net.ConnectException: Connection refused: connect

** END NESTED EXCEPTION **

补充说明：
不是防火墙，端口等问题。因为我写一个小测试类是可以连接数据库的。
应该是配置文件的问题。我把配置文件也发上来

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3330/xtest"/>
<property name="user" value="root"/>
<property name="password" value="admin"/>
<property name="maxPoolSize" value="10"/>
<property name="minPoolSize" value="1"/>
<property name="initialPoolSize" value="1"/>
<property name="maxIdleTime" value="100"/>
</bean>
