XmlBeanFactory和ApplicationContext读取spring xml配置文件

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：
