You do not need onException if you have an errorHandler (see below).
If an error happens, Camel retries 5 times and if all fail then send a
message to deadLetterUri.
You might set another route in deadLetterUri.
- routeConfiguration:
errorHandler:
id: errorHandler-7273
deadLetterChannel:
deadLetterUri: amqp:dlq
id: deadLetterChannel-b9b4
redeliveryPolicy:
id: redeliveryPolicy-5119
maximumRedeliveries: 5
redeliveryDelay: '1000'
- route:
id: route-bbc3
from:
uri: kamelet:timer-source
id: from-d6c4
parameters:
repeatCount: 1
message: Route started
steps:
- to:
uri: http
id: to-3216
parameters:
httpUri: localhost:2000/test
httpMethod: GET
- log:
message: Route finished
id: log-75cd
