如何在 heroku 上为 java 服务器制作 procfile?
How to make procfile for java server on heroku?
我花了一天时间尝试 运行 java xmpp fcm 服务器 Google Firebase 消息传递。
在 example 在 Heroku 服务上建立服务器之后,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.
直到现在,我尝试使用如下命令启动它:
web: java -cp target/classes/:target/dependency/* com.wedevol.xmpp.server.CcsClient
但它不起作用。
$ 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 returns:
=== 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 运行 成功 Java 服务器(来自上面的 link)。
谢谢!

经过几个小时的痛苦终于得到了 Java 服务器的正确 Procfile:

*上传前不要忘记构建项目:
mvn package
