Configuring the Wildcard filter
The Wildcard filter applies a wildcard pattern to the message payload. This filter applies
toString() to the payload, so you might also want to apply a payload type filter to the message using an And filter to make sure the payload is a string.
After dragging the Wildcard filter from the palette and dropping it on the canvas, double-click on the filter icon. A Pattern Property window shows up. There is only one attribute to configure for this filter and it is the pattern. You will see the example of using the Wildcard filter in this section.
How to do it...
In this section, you will use three components: the HTTP Endpoint, the Wildcard filter, and the Custom transformer.
