Content Enricher

Overview

A content enricher is a pattern for augmenting a message with missing information. The ServiceMix EIP content enricher is more or less equivalent to a pipeline that adds missing data as the message passes through an enricher target. Consequently, when migrating to FUSE Mediation Router, you can re-implement the ServiceMix content enricher as a FUSE Mediation Router pipeline.

Example ServiceMix EIP route

The following example shows how to define a content enricher using the ServiceMix EIP component. Incoming messages pass through the enricher target, test:additionalInformationExtracter, which adds some missing data to the message before the message is sent on to its ultimate destination, test:myTarget.

<eip:content-enricher service="test:contentEnricher" endpoint="endpoint">
  <eip:enricherTarget>
    <eip:exchange-target service="test:additionalInformationExtracter" />
  </eip:enricherTarget>
  <eip:target>
    <eip:exchange-target service="test:myTarget" />
  </eip:target>
</eip:content-enricher>

Equivalent FUSE Mediation Router XML route

The following example shows how to define an equivalent route using FUSE Mediation Router XML configuration:

<route>
  <from uri="jbi:endpoint:http://progress.com/demos/test/contentEnricher/endpoint"/>
  <to uri="jbi:service:http://progress.com/demos/test/additionalInformationExtracter"/>
  <to uri="jbi:service:http://progress.com/demos/test/myTarget"/>
</route>

Equivalent FUSE Mediation Router Java DSL route

The following example shows how to define an equivalent route using the FUSE Mediation Router Java DSL:

from("jbi:endpoint:http://progress.com/demos/test/contentEnricher/endpoint").
    to("jbi:service:http://progress.com/demos/test/additionalInformationExtracter").
    to("jbi:service:http://progress.com/demos/test/myTarget");
