hibernate指定jdbc配置文件

hibernatge如何指定jdbc配置文件呢?

jdbc配置文件型如:

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://182.92.94.71:3306/test
jdbc.username=root
jdbc.password=123456

 

在hibernate的配置文件中有两种方式指定jdbc配置文件

方式一:

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

 

方式二:

<context:property-placeholder location="classpath:jdbc.properties" />

 

beans.xml的完整内容如下:
