创建项目

要在 App Engine 上部署应用，您必须创建 Google Cloud 项目，该项目是一个保留 App Engine 应用资源及其他 Google Cloud 资源的顶级容器。

在本任务中，您将创建一个 Google Cloud 项目和一个 App Engine 应用来存储应用的设置、计算资源、凭据和元数据。

如果您已有启用了 App Engine 和 Cloud Build API 的 Google Cloud 项目，则继续编写 Web 服务。

创建 Google Cloud 项目

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Google Cloud project.

4. Enable the Cloud Build API.

   Enable the API

5. Install the Google Cloud CLI.

6. To initialize the gcloud CLI, run the following command:

   gcloud init

7. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

8. Make sure that billing is enabled for your Google Cloud project.

9. Enable the Cloud Build API.

   Enable the API

10. Install the Google Cloud CLI.

11. To initialize the gcloud CLI, run the following command:

    gcloud init

12. 在 Google Cloud 控制台中为您的 Google Cloud 项目创建 App Engine 应用。

    打开应用创建

13. 选择您希望应用的计算资源所位于的区域。

    注意：创建 App Engine 应用后，您无法更改区域。为降低延迟，请选择与您的应用的目标用户最靠近的区域。如需详细了解可用区域，请参阅 App Engine 位置。

后续步骤

现在您的 Google Cloud 项目已设置完毕，您可以开始使用 Java 编写基本的 Web 服务了。
