英文:

I am struggling with this issue for a couple of days and couldn't find anything on SO and the description of error codes on heroku is to vague for me to figure out anything.I have created a basic app with no db integration, with spring framework , thymeleaf and spring mail.I have no spring security.After successfully deploying it to heroku i try to start the application server and this is what i get in the heroku logs.The app works fine on localhost with no issue.

这里的文档中,错误代码H20的含义是:

路由器将在等待启动进程达到“启动”状态的过程中将请求排队等待75秒。如果在75秒后没有Web dyno达到“启动”状态,路由器将记录H20并提供标准错误页面。

如果您的应用程序需要更多时间来启动,您可以使用启动超时工具来增加限制。然而,一般情况下,启动时间较长会使部署应用程序变得更加困难,并且会使从dyno故障中恢复的速度变得更慢,因此这应该被视为一种临时解决方案。

英文:

From the docs here error code H20 means

> 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

If your application requires more time to boot, you may use the boot timeout tool to increase the limit. However, in general, slow boot times will make it harder to deploy your application and will make recovery from dyno failures slower, so this should be considered a temporary solution

尝试将引导超时设置为120秒 - 一些SpringBoot应用程序需要一些时间来引导。可以按照这里所示的方式执行请求:https://devcenter.heroku.com/changelog-items/364

另外,健康检查过程基于HTTP请求,因此请确保您的应用程序通过常规的Web端口(80、8080、443)提供服务。

英文:

Try to set boot timeout to 120 seconds - some SpringBoot apps take some time to boot. The request can be done as shown here: https://devcenter.heroku.com/changelog-items/364

Also, the health check process is based on HTTP requests, so be sure that your app is served through normal Web ports (80, 8080, 443).
