01.Spring内置数据源配置
Class:DriverManagerDataSource
全限定名：org.springframework.jdbc.datasource.DriverManagerDataSource
不需要添加任何jar
02.apache的 dbcp数据源配置
Class:BasicDataSource
全限定名：org.apache.commons.dbcp.BasicDataSource
需要添加：com.springsource.org.apache.commons.dbcp-1.2.2.osgi.jar
com.springsource.org.apache.commons.pool-1.5.3.jar
03.c3p0的 数据源配置
Class：ComboPooledDataSource
全限定名：com.mchange.v2.c3p0.ComboPooledDataSource
需要添加：com.springsource.com.mchange.v2.c3p0-0.9.1.2.jar
引用外部的数据源配置信息设置：${jdbc.*}
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
jdbc.properties
1 jdbc.driver=oracle.jdbc.driver.OracleDriverjdbc.properties
2 jdbc.url=jdbc\:oracle\:thin\:@localhost\:1521\:orcl
3 jdbc.user=zym
4 jdbc.password=zymm
引用jdbc.properties 的两种方式书写：
<!-- 01.让Spring去寻找jdbc.properties -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties"></property>
</bean>
<!-- 02.让Spring去寻找jdbc.properties -->
<context:property-placeholder location="classpath:jdb.properties"/>
