Spring: Creating a java.util.Properties Bean

The easiest way to create a java.util.Properties bean in Spring is with a PropertiesFactoryBean as shown in the example below:

<bean id="emailProperties"
      class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="properties">
    <value>
        smtp.host=mail.host.com
        from=joe.bloggs@domain.com
        to=${mail.recipients}
    </value>
  </property>
</bean>

Spring will parse the key=value pairs and put them into the Properties object.
