Hello,
In my team we are currently attempting to develop a Spring Boot 2.4.2 gateway
application which uses Apache Camel 3.7.1 to expose generic http routes using
the Undertow component and routes using the REST DSL.
I assume that we are not correctly configuring the application since given the
pom.xml below and having manually configured the RestComponent to use undertow
as consumer, it seems two embedded Undertow instances are started. The logs
below show this.
When the test run they fail since they expect the endpoints to be found on port
9080.
Does anyone know what we are doing wrong or misconfiguring in this case?
