Apache Camel 3.x Upgrade Guide

This document is intended for helping you upgrade your Apache Camel application from Camel 3.x to 3.y.

Important

If you are migrating from Camel 2.x then use the Camel 2.x to 3.0 Migration Guide.

For example if you are upgrading Camel 3.0 to 3.2, then you should follow the guides from both 3.0 to 3.1 and 3.1 to 3.2.

Upgrading Camel 3.0 to 3.1

The camel-nats component has changed its endpoint syntax from nats:servers to nats:topic. For example before

nats:myserver:4222?topic=myTopic

Should be changed to

nats:myTopic?servers=myserver:4222

This change is motivated by allowing to configure servers on component level, and also for Spring Boot auto-configuration etc.

The camel-nsq component has changed its endpoint syntax from nsq:servers to nsq:topic. For example before

nsq:myserver:4161/myTopic

Should be changed to

nsq:myTopic?servers=myserver:4161

This change is motivated by allowing to configure servers on component level, and also for Spring Boot auto-configuration etc.
