I asked this same question before and this the example and answer I got about using a Map with Jackson.
<dataFormats> <!-- here we define a Json data format with the id jack and that it should use the TestPojo as the class type when doing unmarshal. The unmarshalTypeName is optional, if not provided Camel will use a Map as the type --> <json id="jack" library="Jackson" unmarshalTypeName="org.apache.camel.component.jackson.TestPojo"/> </dataFormats> I did not test it to confirm that it works correctly though.

I just wonder what a good solution would be? Either the user would need to explicit configure this on the data format? Or we can look into a fallback type converter, so Camel automatic an convert to a List/Map for you. And if you want you can use <convertBodyTo type="java.util.List"/> And then the fallback type converter would kick in.
