Java泛型，如何擷取T的class

public class TypeReference<T> {

    private final Type type;

    protected TypeReference(){
        Type superClass = getClass().getGenericSuperclass();

        type = ((ParameterizedType) superClass).getActualTypeArguments()[0];
    }

    public Type getType() {
        return type;
    }
    
    public final static Type LIST_STRING = new TypeReference<List<String>>() {}.getType();
}



    public static void main(String args[]) {


        List<Integer> list = new ArrayList<>();
        list.add(1);
        list.add(2);
        list.add(3);

        List<Integer> list11 = JSON.parseObject(json, new TypeReference<List<Integer>>(){});

        System.out.println("list11:" + list11);

    }
