spring配置数据库驱动

1.利用hibernate.properties文件加载

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
　　<property name="locations">
　　　　<list>
　　　　　　<value>classpath:hibernate.properties</value>
　　　　</list>
　　</property>
</bean>

或者

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
　　<property name="driverClassName" value="${hibernate.connection.driver_class}" />
　　<property name="url" value="${hibernate.connection.url}" />
　　<property name="username" value="${hibernate.connection.username}" />
　　<property name="password" value="${hibernate.connection.password}" />
　　<property name="initialSize" value="${hibernate.initialSize}" />
　　<property name="maxActive" value="${hibernate.maxActive}" />
</bean>

hibernate.properties文件（oracle）

hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
hibernate.connection.url=jdbc\:oracle\:thin\:@127.0.0.1\:1521/abc
hibernate.connection.username=root
hibernate.connection.password=123456

hibernate.properties文件（mysql）

hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.url=jdbc\:mysql\://127.0.0.1\:3306/disc_shop?useUnicode\=true&characterEncoding\=utf8
hibernate.connection.username=root
hibernate.connection.password=123456

2.直接配置

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
<property name="username" value="roott"></property>
<property name="password" value="123456"></property>
<property name="url" value="jdbc:oracle:thin:@192.168.10.197:1521:abc"></property>
</bean>
