这里的java代码要配合部署的归集合约才可以实现
这里只做展示效果

// TODO: 这三步需要分步进行
    public static void main(String[] args) throws IOException {
        List<String> fromAddressList = new ArrayList<>();
        JSONArray jsonArray = getPrivateKey();
        // TODO: 1.授权时需要挨个扣手续费
        for (int i = 0; i < jsonArray.size(); i++) {
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            String address = jsonObject.getString("address");
            String privateKey = jsonObject.getString("privateKey");
            // TODO: 授权合约
            approve(address, privateKey);
            fromAddressList.add(address);
        }
        // TODO: 2.查询不需要扣手续费，如果上面执行成功了，这一步能查询到授权金额就是成功了
        for (int i = 0; i < jsonArray.size(); i++) {
