All use the following for doing this programmatically 

XmlBeanFactory factory = new XmlBeanFactory(new FileSystemResource("beans.xml"));
PropertyPlaceholderConfigurer cfg = new PropertyPlaceholderConfigurer();
cfg.setLocation(new FileSystemResource("jdbc.properties"));
cfg.postProcessBeanFactory(factory);

Use the PropertiesFactoryBean to inject the Properties in a Bean.

<bean id="myPropertiesBean"
  class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="location" value="classpath:ErrorMessage.properties"/>
</bean>

This provides a Properties Object/Bean which can be injected under the name myPropertiesBean in any Bean (<property name="x" ref="myPropertiesBean"/>).

In addition Spring provides the util namespace (since Spring 2.5): There you can write the PropertyFactoryBean definition a bit shorter:

<util:properties id="myPropertiesBean"
 location="classpath:ErrorMessage.properties"/>

@see Spring Reference Chapter C.2.2.3.
