Jackson JSON Deserialization: array elements in each line

Question

I am using Jackson and would like to pretty-print JSON such that each element in arrays goes to each line, like:

{
  \"foo\" : \"bar\",
  \"blah\" : [
    1,
             


        

Answer 1

You could extend the DefaultPrettyPrinter and override the methods beforeArrayValues(…) and writeArrayValueSeparator(…) to archieve the desired behaviour. Afterwards you have to add your new Implementation to your JsonGenerator via setPrettyPrinter(…).
