deserialize inner JSON object

Question

I have a class POJO

Class Pojo {
String id;
String name;
//getter and setter
}

I have a json like

{
    \"response\" : [
          


        

Answer 1

Pojo pojo;
json = {
    "response" : [
        {
            "id" : "1a",
            "name" : "foo"
        }, 
        {
            "id" : "1b",
            "name" : "bar"
        }
    ]
}
ObjectMapper mapper = new ObjectMapper();
JsonNode root = objectMapper.readTree(json);
pojo = objectMapper.readValue(root.path("response").toString(),new TypeReference>() {});

First, you have to create a JSON node with your JSON file. Now you have a JSON node. You can go to the desired location using path function of JSON node like what I did

root.path("response")

However this will return a JSON tree. To make a String, I have used the toString method. Now, you have a String like below " [ { "id" : "1a", "name" : "foo" }, { "id" : "1b", "name" : "bar" } ] " You can map this String with JSON array as following

String desiredString = root.path("response").toString();
pojos = objectMapper.readValue(desiredString ,new TypeReference>() {});
