QUESTION
I am creating a JSON
file using the Jackson JsonGenerator
for which I need to add the elements from List
. This List
consists of the JSON Fragments
which needs to be added to my final JSON
file.
As of now, I am looping over the List
and adding them to my Jackson JsonGenerator writeRaw
one-by-one. This is working fine as of now. However, my List
can have 1000s or more values then I do not wish to loop and add one by one. Rather than that, I am finding a way to directly add the array to the JsonGeneator
array. I wanted to know if there is a way to directly copy the array something like this:

objectNode.put("schema", "2.0");
objectNode.put("date", "2021-06-22");
ArrayNode arrayNode = new ObjectMapper().createArrayNode();
for (String s : eventsList) {
arrayNode.add(new ObjectMapper().readValue(s, ObjectNode.class));
}
objectNode.set("eventList", arrayNode);
System.out.println(objectNode.toPrettyString());
