我有一个在Heroku上部署的Java应用程序。部署就像超级按钮一样工作,没有错误或警告,该应用程序开始运行。但是,一段时间后,出现以下错误:
错误R10(引导超时)-> Web进程在启动后90秒内未能绑定到$ PORT
在本地运行我的应用程序时没有任何错误。
FYI::此应用会定期检查postgresql数据库中的表是否进行了更改,如果有更改,则更新同一数据库中的另一个表(据我所知)确实与我的问题有关,但您可以继续。)
这是日志:

行(以及类似的行)包含我应用程序的一些临时输出,以表明它实际上在做某事。对于每行,该程序都会检查表是否存在更改,如果有更改,是否需要采取措施(如果需要采取措施,则应用程序的输出会更有意义)。
如您所见,该应用程序可以正常启动,运行一段时间,然后崩溃甚至重启。但是,有时它会完全停止工作。

...和我的Procfile:
web: java $JAVA_OPTS -Dserver.port=$PORT -cp target/classes:target/dependency/* nl.limakajo.numbersbackend.Main
经过大量Google搜索和浏览后,我没有找到解决方案。
答案 0 :(得分:1)
听起来您希望此过程在后台运行而不处理Web请求。在这种情况下,您不想在web:
中使用Procfile
。在Heroku上,web
进程受到特殊对待:它被分配了一个PORT
env var,必须在启动后的90秒钟内绑定到该变量。
我建议将您的Procfile
更改为:
worker: java $JAVA_OPTS -cp target/classes:target/dependency/* nl.limakajo.numbersbackend.Main
