gson反序列化列表元素列表

Question

我正在尝试反序列化包含person对象的列表的列表，但是会出现错误。

            gson = new Gson();
            Type listType = new TypeToken<List<List<Person>>>(){}.getType(); 
            List<List<Person>> persons = gson.fromJson("[['1','Mark'],['2','Dave']]", listType); 
            System.out.println("persons:" +persons);

错误：-

Exception in thread "main" com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 4 path $[0][0]

Person.java

class Person{
    private String id;
    private String name;
    Person(){

    }
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}
