1、使用XmlBeanFactory读取spring配置文件，可以如下：

Resource resource=new ClassPathResource("conf/spring/applicationContext.xml");
      BeanFactory factory=new XmlBeanFactory(resource);
    
     com.geostar.query.beans.DataSource ds=(com.geostar.query.beans.DataSource)factory.getBean("ds");
    System.out.println(ds.getDriverClassName());

控制台：

log4j:WARN No such property \[maxBackupIndex\] in org.apache.log4j.DailyRollingFileAppender.  
log4j:WARN No such property \[maxFileSize\] in org.apache.log4j.DailyRollingFileAppender.  
$\{google.database.driverClassName\}

\------下面是我的spring配置部分：

<bean id="ds" class="com.geostar.query.beans.DataSource">  
<property name="driverClassName">  
<value>$\{google.database.driverClassName\}</value>  
</property>  
<property name="url" >  
<value>$\{google.database.url\}</value>  
</property>  
<property name="userName">  
<value>$\{google.database.username\}</value>  
</property>  
<property name="passWord">  
<value>$\{google.database.password\}</value>  
</property>  
<property name="tableName">  
<value>$\{google.database.tablename\}</value>  
</property>  
<property name="fieldName">  
<value>$\{google.database.fieldname\}</value>  
</property>  
<property name="orderFieldName">  
<value>$\{google.database.orderfieldname\}</value>  
</property>  
</bean>

2、使用ApplicationContext

ApplicationContext factory=new ClassPathXmlApplicationContext("classpath:conf/spring/applicationContext.xml");
        DataSource  ds=(DataSource)factory.getBean("ds");
        System.out.println(ds.getDriverClassName());

控制台：
