Auth.net Java SDK 中 com.auth.net.commons.authorize.net.GetSettledBatchList.main 的线程“main”java.lang.NullPointerException 中的异常

Question

我需要Authorized.net Java SDK 专家的帮助。我是GetSettledBatchList事务，使用以下代码，但它给了我例外，我无法理解它接受哪种日期格式。

错误仅供参考：

11/05/15 00:32:56,875:  INFO [pool-1-thread-1] (net.authorize.util.LogHelper:24) - Use Proxy: 'false'
Exception in thread "main" java.lang.NullPointerException
    at com.auth.net.commons.authorize.net.GetSettledBatchList.main(GetSettledBatchList.java:52)

到目前为止我开发的代码供参考：请帮助我如何解决这个错误。

第 52 行的内容为空。尝试添加空检查：

if (getResponse!=null && getResponse.getMessages() != null && getResponse.getMessages().getResultCode() != null) {

        if (getResponse.getMessages().getResultCode() == MessageTypeEnum.OK) {
            if (getResponse.getMessages().getMessage() != null && getResponse.getMessages().getMessage().get(0) != null) {
                System.out.println(getResponse.getMessages().getMessage().get(0).getCode());
                System.out.println(getResponse.getMessages().getMessage().get(0).getText());
            }
        }
        else{
            System.out.println("Failed to get settled batch list:  " + getResponse.getMessages().getResultCode());
        }
}

第 47 行在您的代码中没有意义。线

GetSettledBatchListResponse getResponse = new GetSettledBatchListResponse();

从 API 返回一个空响应。您没有任何行来实际从控制器中提取响应。

如果您在 Authorize.Net GitHub 存储库中查看示例代码的 link，您会注意到上面的行应该替换为

GetSettledBatchListResponse getResponse = controller.getApiResponse();

试试这个，然后将结果返回给我们。

此问题已在最新版本的anet-java-sdk 1.8.6 每个链接https://github.com/AuthorizeNet/sdk-java/issues/61 中得到修复。所以下面的代码工作正常。确保在使用日期时，FirstSettlementDate 和 LastSettlementDate 间隔不应超过 30 天。

public class SettledTransactionDetails {
    public static final String apiLoginID= "XXXXX";
    public static final String transactionKey= "XXXXXX";

    @SuppressWarnings("unchecked")
    public static void main(String[] args) throws ParseException {
        Merchant merchant = Merchant.createMerchant(Environment.SANDBOX, apiLoginID, transactionKey);

        // get the list of Unsettled transactions 
        net.authorize.reporting.Transaction transaction =
                merchant.createReportingTransaction(TransactionType.GET_SETTLED_BATCH_LIST);

        ReportingDetails reportingDetails = ReportingDetails.createReportingDetails();

        SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
        reportingDetails.setBatchFirstSettlementDate(formatter.parse("16/06/2015"));
        reportingDetails.setBatchLastSettlementDate(formatter.parse("15/07/2015"));
        reportingDetails.setBatchIncludeStatistics(true);
        transaction.setReportingDetails(reportingDetails);

        Result<Transaction> result =(Result<Transaction>) merchant.postTransaction(transaction);
        System.out.println("Result : " + result.getResultCode());

        ArrayList<BatchDetails> batchDetailsList = result.getReportingDetails().getBatchDetailsList();
        for (int i = 0; i < batchDetailsList.size(); i++) {
            ArrayList<BatchStatistics> batchStatisticsList = batchDetailsList.get(i).getBatchStatisticsList();
            for (int j = 0; j < batchStatisticsList.size(); j++) {
                BatchStatistics batchStatistics = batchStatisticsList.get(j);
                System.out.println("====================== "  + j+ " start");
                System.out.println("Account Type : [" + batchStatistics.getAccountType()+"]");
                System.out.println("Charge Amount : [" + batchStatistics.getChargeAmount()+"]");
                System.out.println("Charge BackAmount : [" + batchStatistics.getChargebackAmount()+"]");
                System.out.println("Charge Charge Back Amount : [" + batchStatistics.getChargeChargebackAmount()+"]");
                System.out.println("Charge Returned Items Amount [: " + batchStatistics.getChargeReturnedItemsAmount()+"]");
                System.out.println("Refund Amount : [" + batchStatistics.getRefundAmount());
                System.out.println("Refund Charge Back Amount : [" + batchStatistics.getRefundChargebackAmount());
                System.out.println("Account Type : [" + batchStatistics.getAccountType());
                System.out.println("====================== "  + j+ " end");
            }
        }

    }
}
