Question

I have a @Controller with a @RequestMapping functions that accept collections.

Imagine something like:

requestHandler(Collection<Long> param){
   ...
}

This mapping only matches when I send requests such as:

http://www.domain.com/mapping/funct?param=1&param=2&param=3

I’d like to match it as well when I send a comma sepparated value:

 http://www.domain.com/mapping/funct?param=1,2,3

Is there a way without using .split ? I’d like it to be automatically parsed to a collection.

You would have to write a custom Converter and register it in your Spring MVC context.
