Answer 1

public static void main(String[] args) {
    //初始化一个List
    List<Province> list = new ArrayList<>();
    //声明范型的实体1
    Province c1 = new Province();
    c1.setProvinceName("南京");
    c1.setProvinceSort("1");
    //声明范型的实体2
    Province c2 = new Province();
    c2.setProvinceName("北京");
    c2.setProvinceSort("2");
    //加入List中
    list.add(c1);
    list.add(c2);
    //打印JSON格式的串
    System.out.println(JSON.toJSON(list).toString());
}

[{"provinceName":"南京","provinceSort":"1"},{"provinceName":"北京","provinceSort":"2"}]

Answer 2

如果这个是个字符串就先把前后两个[]去掉 转jsonArray.
