使用 Jackson 仅使用规范类型字符串反序列化 JSON

Question

I have a JSON string

{
    "type": "com.example.model.Person",
    "data": {
        "firstName": "Bob",
        ...
    }
}

That is represented by the following class.

public class Container<T> {
    private String type;
    private T data;

    // Getters and Setters
}

(I've even tried just removing the generic type and replacing it with Object .)

I have tried the following:

• new ObjectMapper().readValue(json, Class.forName(canonical))
• new ObjectMapper().readValue(json, TypeFactory.defaultInstance().constructFromCanonical(canonical))

I need to be able to deserialize the JSON string into a Container<T> instance with only the given canonical type string. How can this be done?
