I now have something that works.
After reading enough of the Scala DSL unit tests, I added the following to my
route builder:
handle[Exception] {
log(LoggingLevel.ERROR, "${id} ${exception}")
to(failureEndpoint)
}.handled
It doesn't appear to be necessary to call maximumRedeliveries(0) on handle,
since I don't get retries when I do this.
This is not ideal because I would prefer this to be a single statement, e.g.
using a custom component, to be able to customise the log output, and to
include the stack trace. I may get to those things, but I've run out of time
for now.
