Writing JSON arrays on multiple lines using Jackson in Java [duplicate]

I started to use Jackson a few days ago and I find this library super powerful, but there is something I couldn't manage to do : write arrays on multiple lines.

I have the following code :

import com.fasterxml.jackson.core.JsonProcessingException; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.databind.node.ArrayNode; public class App { public static void main(String[] args) { ObjectMapper mapper = new ObjectMapper(); ArrayNode node = mapper.createArrayNode(); node.add("1"); node.add("2"); node.add("3"); try { System.out.println(mapper.writerWithDefaultPrettyPrinter().writeValueAsString(node)); } catch (JsonProcessingException e) { e.printStackTrace(); } } } 

With that I get this :

[ "1", "2", "3" ] 

But I want this :

[ "1", "2", "3" ] 

How could I do that ?

Thanks
