I have a number of situations where i have different parts of a route that
repeat consistently but Id rather not create separate routes or direct
calls because I want avoid a bottleneck. If i create 50 routes concurrently
consuming off of one queue and route them all through the same direct, the
direct itself would become a bottleneck. What I would like to do is to
create the route parts in a helper method and then attach them to the
route. For example:
.setHeader("X", simple("${header.url}")
.setHeader("y", simple("${header.something_else}")
... and so on for 10 headers.
.to("http:myendpoint.com")
What I would like to do is declare a method that contains all of that and
then do something like:
from("...") // so on and rest of non-common route
.attach(myRoutePartBuilder())
.to(" ... ") // and so on.
One example of how this effects me is that I have a number of different
handlers that resemble the following:
.onException(Exception.class).useOriginalMessage().handled(true).maximumRedeliveries(0)
// catch exceptions
.setHeader(Exchange.FAILURE_ROUTE_ID,
property(Exchange.FAILURE_ROUTE_ID)) // set route that failed
.setHeader(Exchange.EXCEPTION_CAUGHT,
simple("${exception.stacktrace}")) // Store reason for error
.to(ExchangePattern.InOnly,
endpointAMQ(QUEUE_CASE_AUTOMATION_DEAD)).end() // to DLQ
I have about 3 versions of this that are slightly different and used in
over 2 dozen routes. I have to copy paste that part all over. Furthermore I
cant do this as a global handler because the variants are handling the same
exceptions in slightly different ways. What I want is:
.onException(buildExceptionHandler1())
.to("...") // so on
and
.onException(buildExceptionHandler2())
.to("...") // so on
So any ideas how this could be accomplished with 2.12.x? If not, any advice
on how to handle these issues without creating performance bottlenecks?
TIA
