Spring + GAE +休眠，不能在谷歌服务器上工作

我想让我的项目在线，但它不会工作，但它在devserver上正常工作，但是当我尝试访问在线时，我得到了以下日志：Spring + GAE +休眠，不能在谷歌服务器上工作

JDBC配置：

jdbc.username=**** 
jdbc.password=***

正如我所说，在devserver上它工作正常，我使用Spring 4.0.7.RELEASE和休眠4.3.5.FINAL。我的MySQL数据库是alwaysdata（仅适用于MySQL的免费的主机，我发现可以从外部访问）

你如何访问你的数据库？ HTTP？ – 2014-10-05 11:58:37

不知道，编辑我的帖子来添加我的jdbc配置文件。 – badoualy 2014-10-05 12:02:21

我不会做Java，但是在Python中，您不能仅仅连接到另一个数据库，所需的传输不可用。因此，除非您可以通过HTTP连接到外部数据库，否则您必须使用Google SQL实例或使用数据存储本身。 – 2014-10-05 14:34:07

大家都知道GAE不允许threads或Threadpool，由于您收到此异常。

所以你必须删除管理你的数据库池的spring JPA类。如果您需要拥有数据库池，那么您必须创建自己的池类，而不需要threads。

您可以查看在谷歌应用程序引擎https://cloud.google.com/appengine/articles/spring_optimization App Engine是很好的与Spring 3.x和下面，从春天4.x中是好的与annoation和应用程序引擎建议，以避免component.scan的链接春天。要使用4.x，你可以使用延迟加载
