JSON - 如何使用 Jackson 处理复杂的反序列化到对象的数据结构

{
    "id": "957c43f2-fa2e-42f9-bf75-6e3d5bb6960a",
    "name": "The Best Product",
    "brand": {
        "id": "9bcd817d-0141-42e6-8f04-e5aaab0980b6",
        "name": "ACME Products",
        "owner": {
            "id": "b21a80b1-0c09-4be3-9ebd-ea3653511c13",
            "name": "Ultimate Corp, Inc."
        }
    }  
}

public class Product {
    // ...
 
    @SuppressWarnings("unchecked")
    @JsonProperty("brand")
    private void unpackNested(Map<String,Object> brand) {
        this.brandName = (String)brand.get("name");
        Map<String,String> owner = (Map<String,String>)brand.get("owner");
        this.ownerName = owner.get("name");
    }
}
