MuleSoft ESB Message Enricher
- 1. MuleSoft ESB Message Enricher By AKASH PRAJAPATI
- 2. Save Message/Payload for feature use/ Reference Topics : • Create Mule Project • Add Message Enricher, Process Chain, Multiple Message Processors Purpose : Need to enrich an incoming message with information that isn’t provided by the source system. Use a content enricher if the target system needs more information than the source system can provide. Pre-requisites : • Basic under standing of Mule ESB • JDK 1.8 or above • Anypoint Studio v 6.0.0 or above • Mule Server v 3.8.0 EE or above
- 3. Create flow – httpServiceFlow :
- 4. Create flow – mainFlow :
