我需要在java中以以下格式反序列化json的帮助：
数据.json

{
   "tokens":[
      {
         "position":1,
         "text":"hello",
         "suggestions":[
            {
               "suggestion":"hi",
               "points":0.534
            },
            {
               "suggestion":"howdy",
               "points":0.734
            }
         ]
      },
   ]
}

我创建了两个类，一个称为token，另一个称为suggestion，属性与json格式匹配。
令牌.java

public class Token {
    private int position;
    private String text;
    private List<Suggestion> suggestions;

    public Token(int position, String text, List<Suggestion> suggestions) {
        this.position = position;
        this.text = text;
        this.suggestions = suggestions;
    }
}

建议.java

public class Suggestion {
    private String suggestion;
    private double points;

    public Suggestion(String suggestion, double points) {
        this.suggestion = suggestion;
        this.points = points;
    }

}

如何将json“解压”到一个令牌列表中，每个令牌都有两个必需的字符串和一个建议对象列表作为其属性(理想情况下，它将使用gson库）
我试过了，但没用：

Gson gson = new Gson();
Type listType = new TypeToken<List<Token>>(){}.getType();

List<Token> tokenList = gson.fromJson(jsonString, listType);

System.out.println(tokenList.get(0));

谢谢
