Jackson databind MismatchedInputException

Using spring configuration to read data from json into spring bean it works for simple type but i am getting the above error when try to read an array This is my config

@Bean
Container container() throws IOException {

    ObjectMapper objectMapper = new ObjectMapper();

    return objectMapper.readValue(getClass().getClassLoader().getResource("book.json"), Container.class);
}

I have decided to put in a container as suggested so its ok to have my config look like this ? As i will be using these data to create Some spring controllers. POJO CLASS

public class Container {
String requestedUrl;
  List<Item> items;}

This is the json data , 

{
  "requestedUrl": "https://www.googleapis.com/books/v1/volumes?q=java&maxResults=40",
  "items": [
    {
      "kind": "books#volume",

          },
          {
            "type": "ISBN_10",
            "identifier": "1592432174"
          }
        ],

          "image": true
        },
        "printType": "BOOK",

        "country": "PL",
        "saleability": "NOT_FOR_SALE",
        "isEbook": false
      }, //Shortened for brevity

You are passing the json object which is bounded by {} but trying to convert it to array. With this json you should convert to another class like 

public class Container {
    private String requestedUrl;
    private List<Item> items;

    // getters/setters
}
