如何使用 Jackson 作为孩子将 ObjectNode 添加到另一个 ObjectNode 中？

Question

I have the below ObjectNode.

handlerObjectNode -> {"Info":{"Brand":{"BrandName":"TOP OF THE WORLD"}}}

I have another ObjectNode in the following format.

fieldObjects -> {"Description":"REGULAR BR"}

How can I create the below ObjectNode from the above two?

{
   "Info": {
       "Brand": {
           "BrandName": "TOP OF THE WORLD"
       }
   "Description": "REGULAR BR"
   }
 }

I tried the below code.

handlerObjectNode.setAll(fieldObjects);

But it results in the following ObjectNode.

{
   "Info": {
       "Brand": {
           "BrandName": "TOP OF THE WORLD"
       }
   },
   "Description": "REGULAR BR"
 }

I am using the com.fasterxml.jackson.databind.node.ObjectNode from Jackson. Any help would be much appreciated.

Try This,

ObjectMapper mapper = new ObjectMapper();

//create root node
ObjectNode rootNode =  mapper.createObjectNode();

root.put("key1", "value1");
jsonObject.put("key2", "value2");

jsonObject.putArray("array2").add("item1").add("item2").add(12); //tuple
// create child node
ObjectNode childNode = mapper.createObjectNode();
        childNode.put("name", "Hungbeo");
        childNode.put("age", 12);

// add childNode to rootNode
rootNode.set("user", childNode);

System.out.println(rootNode.toString());

Output:

{"key1":"value1","key2":"value2","array":["item1","item2",12],"user":{"name":"Hungbeo","age":12}}

Answer 3

Extract the Info object and add the fieldObjects to that:

ObjectMapper om = new ObjectMapper();

ObjectNode handlerObjectNode = (ObjectNode) om.readTree("{\"Info\":{\"Brand\":{\"BrandName\":\"TOP OF THE WORLD\"}}}");
ObjectNode fieldObjects = (ObjectNode) om.readTree("{\"Description\":\"REGULAR BR\"}");

ObjectNode info = (ObjectNode) handlerObjectNode.path("Info");
info.setAll(fieldObjects);

Results in the following output:

{
  "Info" : {
    "Brand" : {
      "BrandName" : "TOP OF THE WORLD"
    },
    "Description" : "REGULAR BR"
  }
}
