Merging Two JSON Documents Using Jackson

Question

Is it possible to merge two JSON documents with the Jackson JSON library? I am basically using the Jackson mapper with simple Java Maps.

I\'ve tried to search in Goo

Answer 1

If someone simply wants to add two or more JsonNode object into one JsonNode, this can be one approach:

ArrayNode arrayNode = objectMapper.createArrayNode();
arrayNode.add(firstJsonNode);
arrayNode.add(secondJsonNode);
arrayNode.add(thirdJsonNode);

JsonNode root = JsonNodeFactory.instance.objectNode();
((ObjectNode) root).put("", arrayNode);
System.out.println("merged array node #: " + root);
