Hibernate配置Mysql、Oracle、SQL server，參數及驅動配置

applicationContext.xml（spring的配置文件，配置hibernate）

    <!--掃描配置文件-->
    <context:property-placeholder location="classpath:/jdbc.properties" />

    <!--配置數據源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
