This isn’t quite you’re use case since I don’t extend routes, but I have
RouteBuilders that I deploy hundreds of times with different configurations
using either camel-blueprint, camel-scr and Blueprint namespace handlers.
I allow minor variations the routes based on the configuration of the
RouteBuilder, so if I were going to try your example, the configure method
would look something like this:
public void configure() throws Exception {
ProcessorDefinition<?> routeDef =
from("file://").routeId(routeId)
.log(LoggingLevel.INFO, "[FILEREADER], file:
${in.header.CamelFileName}");
if (SPLITTER_ELEMENT_NAME != null && !SPLITTER_ELEMENT_NAME.isEmpty()) {
routeDef = routeDef.split().tokenizeXML(SPLITTER_ELEMENT_NAME).streaming()
}
routeDef.to(queueEndpointUri);
}
Notice that If the SPLITTER_ELEMENT_NAME property is set, then the route will
include the “split”.
I’ve used this technique quite a bit, and I’ll reiterate the comment Claus made
about complexity - be careful with this. MINOR variations of the route are
supportable, but too many allowed variations can make the RouteBuilder very
difficult to support.
