hibernatge如何指定jdbc配置文件呢?

jdbc配置文件型如:

Java代码  
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:

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

方式二:

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

beans.xml的完整内容如下:

Xml代码
