问题 am exploring the usage of Tracer for logging purpose. It can be managed via JMX Console, so logging can be enabled even when developers haven't used logs in their routes. My concern is that Tracer seems to output the same amount of information irrespective of the log level set. Is this case or I am missing something. I am enabling tracing on the route in the Route Builder: getContext().setTracing(true); Date d = new Date(); from("file://c:/test?include=myTest.*.txt&noop=true").routeId(

问题 I would like to use the header value for setting the name of db table in sql component. Is there an easy way to do this? .to("sql:drop table ${in.header.tablename}") throws invalid character exception 回答1: If you want to route the message dynamically, you can use recipient-list. The route could be from("direct:a").recipientList(simple("sql:drop table ${in.header.tablename}")). 回答2: The point of using the sql component instead of the jdbc one is that the former allows you to use the message

问题 I am trying to implement a memory efficient http reverse proxy that is only working on streams. The Jetty consumer places the input stream into the exchange and I can hook it up with a http producer to forward the request. No problem there.

And none of them seem to offer an option
