Implement Write-Behind Cache Event Handling

The Gemfire documentation gives an example at this link of installing a write-behind cache event handler like the following:

Code:

---

<gateway-hub id="DBWriterHub"
  <gateway id="DBWriter">
      <gateway-listener>
        <class-name>com.myApp.myWBCLListener</class-name>
      </gateway-listener>
  </gateway>
</gateway-hub>

---

Looking through the Spring Gemfire Integration Reference Guide I did not see a way to define the gateway-hub and gateway-listener (as defined above) inside the <gfe:cache /> bean definition. How would this be accomplished?

Thanks!
