如何解决与Heroku的Proximo java.net.BindException？ [英] How to fix java.net.BindException with Proximo on Heroku?

问题描述

我在Heroku上安装了Proximo插件，并且在将命令添加到现有命令时，我得到了Java的BindException。这就是我的前缀命令的样子： web：bin / proximo sh target / bin / webapp 并且只要我删除了Proximo部件（ bin / proximo ），应用程序启动时不会出错。

这是完整的堆栈跟踪。我缺少什么？

 线程main中的异常java.net.BindException：无法分配请求的地址
 at sun.nio.ch.Net.bind0（本地方法）
 at sun.nio.ch.Net.bind（Net.java:344）
 at sun.nio.ch.Net.bind（Net .java：336）
 at sun.nio.ch.ServerSocketChannelImpl.bind（ServerSocketChannelImpl.java:199）
 at sun.nio.ch.ServerSocketAdaptor.bind（ServerSocketAdaptor.java:74）
 at org.eclipse.jetty.server.AbstractConnector.doStart（AbstractConnector.java:297）
 at org.eclipse.jetty.server.nio.SelectChannelConnector.open（SelectChannelConnector.java:162）
 at org.eclipse.jetty.server.nio.SelectChannelConnector.doStart（SelectChannelConnector.java:240）

 at org.eclipse.jetty.server.Server.doStart（Server.java:270）
 at org.eclipse.jetty.util.component.AbstractLifeCycle.start（AbstractLifeCycle.java:58）
  

因此：

  web：bin / proximo [您现有的命令] 
  

需要包括这个，例如：

  web：bin / proximo [您现有的命令]  - p $ PORT 
  

或任何您需要指定您的Web进程运行的端口。

I have installed the Proximo add-on on Heroku and when prepending the command to my existing command, I get a BindException from Java. This is how my prepended command looks: web: bin/proximo sh target/bin/webapp and as soon as I remove the Proximo part (bin/proximo), the application starts up with no errors.

This is the full stacktrace. What am I missing?

解决方案

Remember you can only use the port that Heroku provides in the $PORT var.

Therefore:

web: bin/proximo [your existing command]

needs to include this, e.g:

web: bin/proximo [your existing command] -p $PORT

or whatever you need to dictate the port your web process runs on.
