Message Routing Patterns

Routing decides where a message goes next and why. In Java integration systems, that logic can stay clear and local, or it can become scattered across conditionals, broker rules, and configuration files.

Use this section to compare routing patterns that keep message movement understandable even as the number of destinations and rules increases.

In this section

• Content-Based Router in Java
  Route Java messages based on payload or header values when one integration entry point must direct work to different handlers.
• Message Filter Pattern in Java
  Drop irrelevant Java messages early so downstream handlers only process events that match meaningful criteria.
• Dynamic Router in Java
  Change routing decisions in Java integration flows at runtime when rules depend on configuration, state, or tenant context.
