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:

Java代码  

1. jdbc.driverClassName=com.mysql.jdbc.Driver  
2. jdbc.url=jdbc:mysql://182.92.94.71:3306/test  
3. jdbc.username=root  
4. 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  

1. <bean  
2.         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
3.         <property name="locations">  
4.             <value>classpath:jdbc.properties</value>  
5.         </property>  
6.     </bean>  

方式二:

Java代码  

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

beans.xml的完整内容如下:

Xml代码  

1. <?xml version="1.0" encoding="UTF-8"?>
