Apache camel set mongodb collection dynamically - mongodb

Question

I'm trying to create a route where the endpoint depents on the incoming message. The aim is to write into a mongodb in different databases and collection.
I'm looking for an easy way to get the information from the message header and write it in to the <to uri=""/>
<route>
<from uri="jms:topic:BUS_IN" />
<to uri="mongodb:myDb?database=${header.someValue}&collection=storyTeaser&operation=save" />
</route>
Thanks a lot

Answer 1

You could add a second route that sets the header variables:
<route>
<from uri="jms:topic:BUS_IN" />
<camel:setHeader headerName="CamelMongoDbDatabase">
<camel:simple>testmydb</camel:simple>
</camel:setHeader>
<camel:setHeader headerName="CamelMongoDbCollection">
<camel:simple>mycollection</camel:simple>
</camel:setHeader>
<to uri="jms:queue:mongodb.out"/>
</route>
And then add the parameter "dynamicity" in the uri of your first route:
<route>
<from uri="jms:queue:mongodb.out" />
<to uri="mongodb:myDb?database=new_test&collection=old&dynamicity=true&operation=save"/>
</route>

Using Apache Camels toD function https://camel.apache.org/message-endpoint.html will allow you to dynamically set the URI as messages are passed through. The URI allows for simple language https://camel.apache.org/simple.html where we can for instance use the filename to generate a collection.
Heres an example Route:
from(input).routeId("SampleRoute")
.toD("mongodb3://mongoBean?database=myDB&collection=${file:onlyname.noext}&" +
"operation=insert&createCollection=true")
