You can setup a custom DefaultPrettyPrinter using this:

DefaultPrettyPrinter pp = new DefaultPrettyPrinter();
pp.indentObjectsWith(new Lf2SpacesIndenter());
pp.indentArraysWith(new Lf2SpacesIndenter("\r\n"));
mapper.writer(pp).writeValue(new FileOutputStream(outputFile), resultNode);

Take a look at the method provided by DefaultPrettyPrinter HERE
