用Gson解析沒有數據頭的純數組json字符串

無數據頭Json字符串
Json字符串只有數組，而次數組沒有名字，如下

[
  {
    "name": "zhangsan",
    "age": "10",
    "phone": "11111",
    "email": "[e-mail]"
  },
  {
    "name": "lisi",
    "age": "20",
    "phone": "22222",
    "email": "[e-mail]"
  },
  ...
]

Json對應的實體類
對應的實體類如下

public class UserBean {
    private String name ;
    private String age;
    private String phone;
    private String email;
    //省略get，set方法
    ...
}

Gson解析：字符串轉實體類

     Type listType = new TypeToken<List<UserBean>>() {}.getType();
        List<UserBean> users = new Gson().fromJson(userJsonString, listType);
