Hi
There is a @RecipientList annotation you can use in a method in a bean.
And then use a bean in the DSL, eg either .bean / .beanRef / or
.to("bean:xxx") etc.
Your use-case is a bit unusual as you set the body to null, and
therefore accesses the Exchange directly.
And accordingly to the EIPs you would need 2 eips for that
- message translator
- recipient list
So in the end you may need to use 2 eips. But you can give the
@RecipientList a try.
