java - QuickBooks Online Java SDK DataServiceexecuteBatch() 导致 NullPointerException

标签 java quickbooks quickbooks-online intuit-partner-platform

我正在尝试使用 Java SDK v2.2.1 和 ipp v3 来运行 QuickBooks Online 批处理作业:

public int updateQuickBooks(BatchOperation batch) {

    OAuthAuthorizer oauth = new OAuthAuthorizer(
        consumerKey, consumerSecret, accessToken, accessTokenSecret);
    assert(oauth != null);

    Context context = new Context(oauth, QuickBooks.APP_TOKEN, ServiceType.QBO, realmID);
    assert(context != null);

    DataService service = new DataService(context);
    assert(service != null);

    LOG.info("Executing QuickBooks batch operation for " + batch.getBIds().size() + " invoices");
    service.executeBatch(batch);

...以及错误的堆栈跟踪:

您可以从堆栈跟踪中看到，是 DataService 的 executeBatch() 函数导致了错误。

我正在本地主机上运行的 Google App Engine 开发服务器上对此进行测试。我顺利完成了 oAuth 流程，并且获得了访问 key 和访问 secret 。我正在使用我的开发应用程序 token 和消费者 key / secret ，并且我绝对确定凭据是正确的。

无论如何，我将 accessToken 更改为一些硬编码的随机字符串值，但错误是相同的。 SDK 似乎根本无法与 API 端点通信。这可能是 App Engine 环境的问题吗？

更新:

我刚刚遇到this类似的问题，我尝试删除我的 qbapihelper-1.2.0-with-dependencies jar (我只有它和 devkit-2.2.1-with-dependencies jar)，但它没有产生任何影响。

更新2:

这似乎是使用 GAE 和 QBO 的 java SDK 的问题，但不幸的是我没有时间进一步调试这个问题，所以我已经切换到我自己的 Web 服务器(使用 Jetty - 这就是GAE 不需要太多移植工作)。

最佳答案

我建议您在您的系统上尝试一下(不使用 GAE)。如果它运行良好，那么您可能需要配置您的 GAE 环境(可能是一些代理设置？或限制出站请求等)。

我尝试了以下代码，效果很好。 

public void createNoOfPurchaseUsingBatch(int noOfPurchaseInBatch) {

    BatchOperation batchOperation = new BatchOperation();

    for (int i = 1; i <= noOfPurchaseInBatch; i = i + 1) {
        Customer customer = createCustomer();
        batchOperation.addEntity(customer, OperationEnum.CREATE, "bID" + i);
    }
    try {
        this.service.executeBatch(batchOperation);
    } catch (FMSException e) {
        e.printStackTrace();
    }
}

private Customer createCustomer() {
    Customer cust = new Customer();
    cust.setDisplayName("HelloWorld " + UUID.randomUUID().toString().substring(0, 5));
    return cust;
}
