c3p0的简单应用
c3po的使用：
1.到官网找c3po，配置c3p0-config.xml

<?xml version="1.0" encoding="UTF-8"?><c3p0-config>     <!-- This app is massive! -->    <named-config name="ajaxApp">        <property name="acquireIncrement">2</property>        <property name="initialPoolSize">5</property>        <property name="minPoolSize">5</property>                        <property name="maxPoolSize">20</property>        <!-- intergalactoApp adopts a different approach to configuring statement caching -->        <property name="maxStatements">10</property>        <property name="maxStatementsPerConnection">5</property>                <property name="user">system</property><property name="password">long</property><property name="driverClass">oracle.jdbc.driver.OracleDriver</property><property name="jdbcUrl">jdbc:oracle:thin:@192.168.0.2:1521:what</property>    </named-config></c3p0-config>

2.使用
DataSource ds = new ComboPooledDataSource("ajaxApp");
获得数据源，
