如何更改Play框架2.4.1的http端口? [英] How to change the http port for play framework 2.4.1?

问题描述

我来自一个Play 1.2.7应用程序，目前是Play框架2.4.1和Scala的入门.首先，我使用激活器Web ui来管理应用程序，但在那里我无法使该应用程序使用其他http端口.

I come from a play 1.2.7 application and currently getting started with play framework 2.4.1 and scala. For a start I use the activator web ui to manage applications and there I cannot get the application to use a different http port.

我更改了conf/application.conf中的http.port设置，但仍然播放2.4.1尝试绑定到已在使用的端口9000.我尝试的设置是:

I changed the http.port setting in conf/application.conf, but still play 2.4.1 tries to bind to port 9000, which is already in use. The setting I tried is:

http.port=7000

关于如何更改通过激活程序Web ui运行的Play框架2.4.1应用程序的端口的任何建议?

Any suggestion on how to change the port for a play framework 2.4.1 application that is run via the activator web ui?

请注意，如链接的问题中所述，我可以使用

Note that as suggested in the linked question I can use

./activator "run 7000"

在应用程序本身中

使其绑定到端口7000.仍然我的问题是如何通过激活程序Web ui获得相同的行为?

in the application itself to have it bind to port 7000. Still my question is how can I get the same behaviour via the activator web ui?

推荐答案

在项目的build.sbt中添加以下内容，其中<port>应替换为所需的端口号.

Add the following to build.sbt of your project where <port> should be replaced with your desired port number.

build.sbt

build.sbt

fork in run := true
javaOptions in run += "-Dhttp.port=<port>"

运行时Activator UI中预期的控制台输出

Expected console output in Activator UI on run

Setting up Play fork run ... (use Ctrl+D to cancel)

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

p.a.l.c.ActorSystemProvider - Starting application default Akka system: application
p.c.s.NettyServer - Listening for HTTP on /0:0:0:0:0:0:0:0:<port>

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