How can you set the logger (log category / log name) in Camel's onException clause?

Question

I have the following route:

            onException(Exception.class)
                .logExhausted(true)
                .logStackTrace(true)
                .logExhaustedMessageHistory(true)
                .process(new MyErrorProcessor());

            from(uri)
            .process(new MyProcessor());

When an error occurs the logs are printed in the org.apache.camel.processor.DefaultErrorHandler log category. Is there a way to change this to a custom log category? .errorHandler() allows you to set a log category but .onException() doesn't seem to allow it.

Thanks.

Answer 1

You can try something like this:

onException(Exception.class)
                .handled(true)
                .log(LoggingLevel.ERROR, this.getClass().getSimpleName(),
                        "${exception.stacktrace} ${messageHistory(false)}");

You can also look up for more variables here: https://camel.apache.org/manual/latest/simple-language.html

Answer 2

By default, the route ID is used as the logger category. Therefore, set the route ID to class name, and you can then configure logging in the usual way:

from(uri)
    .id(this.getClass().getName())
    .process(new MyProcessor());

(id may have been named routeId in Camel 2; the above works for Camel 3).

Answer 3

You can try

.onException(Exception.class)
            .to("log:logger_name?level=ERROR&multiline=true&showCaughtException=true&showStackTrace=true")
