Mongodb heroku中的应用程序错误（使用play framework）

我在java中使用play-1.2.4框架，并使用MongoDB数据库。在heroku repositary成功推进项目。 并尝试打开我的页面，我仍然看到一个错误：应用程序错误

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

当我输入这个

heroku logs

命令时，出现以下错误

当我使用heroku ps运行heroku进程时，它显示

当我运行heroku运行控制台时，它显示以下错误：

我错过了什么？谁能帮我解决这个问题。

你需要在Heroku上以

%prod

模式运行Play。确保您的

程序文件中有
-%prod
。下面是一个示例
Procfile
：

web:    play run -Xmx256M --%prod --http.port=$PORT -Dprecompiled=true

我的procfile包含这样一个“web:play run--http.port=$port$play_OPTS”，我运行“heroku日志”中的端口号和播放选项。问题是您正在开发模式下运行，而在开发模式下play在Java调试端口上侦听。在Heroku上，您的应用程序只能在一个端口上侦听，而您的应用程序正在尝试在两个端口上侦听。因此，您的
application.conf
可能以某种方式被设置为在prod mode.conf/application.conf文件中调试，而不是使用application.mode=dev，我写的是%production.application.mode=prod。但它仍然是您需要的：
%prod.application.mode=prod
以下是一个示例：
