java - Parse JSONNode using Jackson

I have a JSONNode called itemNode that looks like the following JSON. It is obtained in the function parse() below:

       "items": [
        {
          "base": true,
          "component": {
            "order_id": 9,
            "discriminator": "ALL",
            "product_type": "shoelace",
            "customer_id": 6,
            "id": "yyy"

          },
          "component_id": "123",
          "limit": 4
        },
        {
          "base": false,
          "component": {
            "order_id": 9,
            "discriminator": "ALL",
            "product_type": "shoes",

            "customer_id": 3,
            "id": "xxx"
          },
          "component_id": "124",
          "limit": 1
        }
        ]

Below is how my function looks like:

@Override
public Optional> parse(JsonNode rootNode, String parsePath) {
    JsonNode itemNode = parseAttributePath(rootNode, parsePath);
     //TODO
     // Get the base, product_type, limit from itemNode
}


public JsonNode parseAttributePath(JsonNode rootNode, String parsePath) {
    return rootNode.at(parsePath);
}

I have a List where Items is a class containing:
base, product_type, limit

I need to parse the itemNode in the parse() function to get only the above 3 values.

Please give me some pointers to get only the attributes that I want. Thanks in advance.
