import org.springframework.beans.factory.xml.NamespaceHandlerSupport;

NamespaceHandler that supports the wiring of objects backed by dynamic languages such as Groovy, JRuby and BeanShell. The following is an example (from the reference documentation) that details the wiring of a Groovy backed bean: 
<lang:groovy id="messenger"
    refresh-check-delay="5000"
    script-source="classpath:Messenger.groovy">
<lang:property name="message" value="I Can Do The Frug"/>
</lang:groovy>
