java - 如何在heroku上为java服务器制作procfile？

Question

我花了一天时间尝试运行 java xmpp fcm 服务器来进行 Google Firebase 消息传递。
接下来example为了在 Heroku 服务上建立服务器，我发现我需要创建 procfile 文件。 Procfile是:

A Procfile is a mechanism for declaring what commands are run by your application’s dynos on the Heroku platform.

到目前为止，我尝试使用以下命令启动它:

web: java -cp target/classes/:target/dependency/* com.wedevol.xmpp.server.CcsClient 

但是它不起作用。 $heroku 日志:

2017-01-31T13:14:50.844896+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=vast-forest-64025.herokuapp.com request_id=a8a8b191-3679-4746-abf3-c7766fbb8764 fwd="141.226.161.218" dyno= connect= service= status=503 bytes=

$heroku ps 返回:

=== web (Free): java -cp target/classes/:target/dependency/* com.wedevol.xmpp.server.CcsClient (1) web.1: crashed 2017/01/31 15:13:08 +0200 (~ 5m ago)

我需要你的帮助。我需要在该文件中定义什么才能成功运行 Java 服务器(来自上面的链接)。 谢谢!

Answer 1

经过几个小时的痛苦终于得到了该 Java 服务器的正确 Procfile:

web: java -cp target/classes/:target/dependency/* com.wedevol.xmpp.EntryPoint

*不要忘记在上传之前构建项目:

mvn package
