Java Spring:Heroku应用程序在我添加Google analytics js代码后停止工作

Question

我在Stack Overflow上搜索了这个问题，没有找到与spring相关的内容。 在我在每个html页面上添加Google Analytics js代码之前，我的应用程序运行良好，没有任何问题。 该应用程序使用JavaSpring、thymeleaf、cleardDB（mysql）。 日志显示：

我查看了heroku错误状态代码，它对这个错误的唯一建议是将我的引导超时窗口增加到120秒。但问题依然存在

任何帮助都将不胜感激

更新：从html页面删除Google Analytics脚本后

Answer 1

https://devcenter.heroku.com/articles/error-codes#h20-app-boot-timeout

The router will enqueue requests for 75 seconds while waiting for starting processes to reach an “up” state. If after 75 seconds, no web dynos have reached an “up” state, the router logs H20 and serves a standard error page.

您可能还会遇到R10错误，这会使您的启动进程处于启动状态

https://devcenter.heroku.com/articles/error-codes#r10-boot-timeout

A web process took longer than 60 seconds to bind to its assigned $PORT.

错误在于，在启动程序后的60秒内，您没有收听$PORT
