java - 调试谷歌数据存储 : IllegalArgumentException: projectId must match the following pattern

Question

我正在开发一个应用引擎项目并使用 Google 数据存储存储我的数据。我想调试它，但我仍然有异常 java.lang.IllegalArgumentException: projectId must match the following pattern: ([a-z\d\-]{1,100}~)?([a-z\d][a-z\d\-\.]{0,99}:)?([a-z\d][a-z\d\-]{0,99})

我能够调试我的 Appengine 项目，我可以部署它并将数据正确地存储在 Google Datastore 中。

为了允许调试，我遵循了数据存储模拟器的说明:

https://cloud.google.com/datastore/docs/tools/datastore-emulator

我已经安装了 Google Cloud SDK，并使用我的项目 ID 的默认值正确启动它(我还尝试通过命令行设置我自己的项目 ID)。

这是我在 gcloud 中执行的命令:

gcloud beta emulators datastore start --project="my-project-name"

这是我尝试使用它时的堆栈跟踪:

编辑:代码(我没有包括因为我认为问题不在代码中，因为我部署并且它工作得很好)。在“datastore.newKeyFactory()”中引发异常

Datastore datastore = DatastoreOptions.getDefaultInstance().getService();
Key taskKey = datastore.newKeyFactory().setKind(ENTITY_TYPE_MEDIDAS).
    newKey(Calendar.getInstance(TimeZone.getTimeZone("CET")).getTimeInMillis());
Entity.Builder task = Entity.newBuilder(taskKey)
        .set(PROPERTY_COMPUESTO, DATA_COMPUESTO)
        .set(PROPERTY_AVISO,DATA_AVISO);
Entity entity = task.build();
datastore.put(entity);

目前尚不清楚您是在寻找连接到数据存储模拟器(用于开发)的示例还是 Google Cloud Platform 上的真实数据存储。看起来您的主要目标是从 IDE 调试您的代码，您可以通过任何一种方式进行调试。

要连接到数据存储模拟器 - 请参阅以下帖子:

Google Datastore Emulator using Java (Not using GAE)

用于连接到 GCP 上的数据存储 -

如果您尚未运行 glcoud init 命令，请运行它并按照屏幕上的说明设置默认项目和身份验证凭据。然后你可以使用下面的代码访问真正的数据存储:

Datastore datastore = DatastoreOptions.getDefaultInstance().getService();

其他选项是使用 DatastoreOptions.Builder 在代码中设置项目 ID 和 Auth Credentials。您需要从 Google Cloud Console 获取/下载 JSON 凭证。
