Hi,
I'm building my first application using Camel and have a question
about how to use a splitter.
My route receives a serialized Java class which contains a private
ArrayList of a POJO and getter and setter methods for the list.
I convert the serialized class into a its Java representation and then
apply it to a splitter. What I want to get out of the Splitter is
each individual instance of the POJOs in the List but what I get
instead is the complete list.
Here is some code to show what I mean
public class ImageCollection {
private List<SingleImageModel> images = new ArrayList<SingleImageModel>();
public void setImages(List) { ... }
public List getImages() { }
}
public class SingleImageModel {
members ...
getters & setters
}
Routes:
The first route accepts a POST from a servlet, validates the incoming
payload and converts it into an instance of ImageCollection, which is
dispatched to the requestQueue, then returns a response to the client.
from("servlet:uploadUrl")
.log("Request: ${body}")
.to("bean:uploadRequestQueue")
.log("${body}")
.marshal().json(JsonLibrary.Jackson)
.wireTap("activemq:requestQueue")
.to("bean:formatResponse")
.end()
The second route is supposed to take the ImageCollection and split it
into the SingleImageModel instances
from("activemq:requestQueue")
.convertBodyTo(ImageCollection.class)
.log("${body}")
.split(bodyAs(ImageCollection.class))
.log("${body}")
.to("bean:downloadImageQueue")
.marshal().json(JsonLibrary.Jackson)
.to("activemq:ftpQueue");
I think I need to use an Aggregator to return the individual instances
of the SingleImageModel class from the list inside ImageCollection,
but I can't work out what that should do.
Instead, what is happening is that the bean registered for the
downloadImageQueue is receiving an instance of ImageCollection when it
expects an instance of SingleImageModel and the type conversion in
that bean is failing.
Any guidance much appreciated.
Thanks,
Charles.
