У меня проблема при разборе JSON с Джексоном. у меня естьPOJO объект, завернутый в другой.

Вот мой код:

in main:
ObjectMapper mapper = new ObjectMapper();

List<ItemBean> mpl2 = mapper.readValue(col.toString(),new TypeReference<List<ItemBean>>() {});
my POJO class:

public class ItemBean implements Serializable {
    private List<Item> items;
    @JsonProperty("Item")
    public List<Item> getItems() {
        return items;
    }
    public void setItems(List<Item> items) {
        this.items = items;
    }
}

public class Item implements Serializable{
    public String field1;
    public Integer field2;

    public static final class Field3 extends GenericJson {
        private String subfield1;
        private String subfield2;
    }
}

И вот брошенное исключение:

org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "item" (Class bean.item), not marked as ignorable
 at [Source: java.io.StringReader@101b6d56; line: 4, column: 16] (through reference chain: bean.ItemBean["items"]->bean.Item["item"])

JSON выглядит так:

["{\n
            \"items\":
        [
        \n  {
        \n \"item\": {
        \n    \"field1\": \"val1\",
        \n    \"field2\": \"val2\",
        \n    \"field3\": [
                        \n     {
                        \n      \"subfield1\": subval
                         \n      \"subfield2\": subval
                        \n     }
                        \n    ]
                        \n   }
                        \n  },
        \n \"item\": {
        \n    \"field1\": \"val1\",
        \n    \"field2\": \"val2\",
        \n    \"field3\": [
                        \n     {
                        \n      \"subfield1\": subval
                         \n      \"subfield2\": subval
                        \n     }
                        \n    ]
                        \n   }
                        \n  },
        \n \"item\": {
        \n    \"field1\": \"val1\",
        \n    \"field2\": \"val2\",
        \n    \"field3\": [
                        \n     {
                        \n      \"subfield1\": subval
                         \n      \"subfield2\": subval
                        \n     }
                        \n    ]
                        \n   }
                        \n  },


etc......   may I haven't closed brackets correctly, but they are correct :)
            }
        ]
    "]

POJO полностью повторяет поля объекта JSON.
