Messaging Mapper¶

This page explains how you can implement a sample scenario of the Messaging Mapper EIP using WSO2 Micro Integrator.

Introduction to Messaging Mapper¶

The Messaging Mapper EIP moves data between domain objects and the messaging infrastructure while keeping the two independent of each other. It contains the mapping logic between the messaging infrastructure and the domain objects. Neither the objects nor the infrastructure have knowledge of the Messaging Mapper's existence.

How WSO2 MI implements the EIP¶

Messaging Mapper's objective is to serialize domain objects into a format more adaptable to the messaging infrastructure, such as SOAP or JSON.

In WSO2 MI, the task of a Message Mapper is simulated by Message Builders and Message Formatters. They provide serialization logic to convert a byte stream to a standard data serialization format such as XML/SOAP or JSON. You can implement custom Message Builders/Formatters and plug them into the WSO2 MI to map just about any domain object into any sort of messaging infrastructure.
