为什么播放框架会超时? [英] why is play framework timing out?

问题描述

我正在使用任一

I am starting the the application from the command line using either

    activator run 
    activator ~run

或者在启动激活器控制台后，我使用run或〜run.
一切似乎都可以正常工作，并且可以提供预期的结果

or after I start the activator console I use run or ~run.
everything seems to work and it gives the expected

 --- (Running the application, auto-reloading is enabled) ---

   play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

   (Server started, use Ctrl+D to stop and go back to the console...)

我可以在浏览器中查看该应用程序，并且可以对代码进行更改，然后将它们重新加载就可以了.问题是，只有几分钟后，这似乎有点超时"，因为如果在此之后我尝试重新加载，浏览器就会停滞不前. 如果我让它旋转足够长的时间，我就会得到.

I can view the application in the browser and I can make changes in the code and they are reloaded just fine. the issue is that after only a couple minutes it seems like something "times-out" because if I try to reload after this the browser just sits there spinning. if i let it spin long enough I get.

[error] application - 
[info] 
[info] ! Internal server error, for (GET) [/] ->
[info] 
[info] java.util.concurrent.TimeoutException: Futures timed out after [300000 milliseconds]

[info]  at scala.concurrent.Await$.result(package.scala:111) ~[scala-library-2.11.1.jar:na]

我将非常感谢您的帮助.由于每次更改后都必须重新启动应用程序，因此确实消除了框架的吸引力.

I would really appreciate any help. Since having to restart the app all over again each time I make a change really takes away the appeal of the framework.

推荐答案

我通过Play 2.3.9升级到了激活器1.3.2，但我也遇到了同样的问题.它让我发疯.我发现原因是激活器1.3.2中添加了新的"fork in run"设置.

I upgraded to activator 1.3.2 with Play 2.3.9 and I also had the same issue. It drove me nuts. I found that the cause was the new set "fork in run" setting added in activator 1.3.2.

打开build.sbt，您将找到:

Open up build.sbt and you will find :

fork in run := true

将其设置为 false ，如下所示:

Set this to false as follows :

fork in run := false
