Playframework 无法读取生产中的数据库表？

Question

我使用 play 1.2.1 来生成我的战争应用程序。我在生产中使用 mysql 5 db 的 tomcat 6。 我已经创建了我的数据库，并将所有本地表导入生产数据库。

在我将我的应用程序部署到 myapps tomcat 目录之后，我重新启动我的服务器，一切都很好，你可以在这样的日志文件中看到。

当我访问主页时出现问题。此错误出现在我的服务器日志中：

在我的产品数据库中，该表存在，但应用程序无法读取我的表。

经过搜索，我找到了this 页面。解决方案是：编辑 application.conf 文件并取消注释 'jpa.ddl=update' 行。
