How to read properties in applicationcontext.xml loading by Spring PropertyPlaceholderConfigurer & Spring util

If we are using PropertyPlaceholderConfigurer to load the properties then we can read the property using $
Example:-
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:config.properties"></property>
</bean>

<!-- Definition for DataSource Start-->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc_driverClassName}" />
<property name="url" value="${jdbc_url}" />
<property name="username" value="${jdbc_username}" />
<property name="password" value="${jdbc_password}" />
</bean>

If we are using util schema to load the properties then we can read the property using #{beanID.propertyName} like #{config.jdbc_driverClassName}

<util:properties id="config" location="classpath:config.properties"></util:properties>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="#{config.jdbc_driverClassName}"/>
<property name="url" value="#{config.jdbc_url}"/>
<property name="username" value="#{config.jdbc_username}"/>
<property name="password" value="#{config.jdbc_password}"/>
</bean>
