The splitter can configure the strategy from the DSL eg using
aggregationStrategy as show:
.split().tokenizeXML("person").aggregationStrategy(new MyStrategy())
If you want 2 outgoing messages, you should use both the splitter and
the aggregator
accordingly to the EIP patterns.
The aggregation strategy on the splitter will combine all the back
into a single outgoing message.
PS: You could then in theory split that message again, if your custom
aggregation strategy build a List<Object> that
contains the 2 messages you want.
