我在将自己的数据库服务器与 Google 网络应用程序结合使用时遇到问题。

我正在使用 eclips(java EE IDE)，安装了所有 google 插件 init，并开发了一个示例 google web 应用程序，将其部署到 web 中。它工作正常。

现在我想在我的应用程序中使用我自己的数据库。(MYSQL 安装在本地主机上)。这里我使用 Hibernate 连接数据库。所有需要的jar文件都放在WEB-INF文件夹下的lib目录下。

当我运行我的应用程序时，它给出了类似 .. 的错误

请给出实现这一目标的任何想法....

最佳答案

您使用 Hibernate 4.3.1 Final 吗？

Hibernate 的 DriverManagerConnectionProvider 尝试创建新线程，这在 GAE 上是不允许的。我也有这个问题。

查看 Google 的 example在 GitHub 上告诉我使用 Hibernate 4.2.0.Final 工作正常。我尝试使用 Hibernate 4.3.1 运行相同的示例并得到相同的异常。但在 4.2 中，它的运行正如预期的那样。

我要在我的应用程序中降级 Hibernate，看看......
