我正在尝试将Play Framework网络服务器添加为大型应用程序的一部分，但该应用程序的主要用途不是Web服务器.它已经接受了各种连接，包括串行和TCP，但是我需要添加WebSocket，并且Play Framework的WebSocket接口是更可取的. (我们尝试过Undertow，但其笨拙的界面遇到了太多问题)

I'm trying to add a Play Framework web server as part of a larger application, but the application's primary purpose is NOT a web server. It already accepts a variety of connections, including serial and TCP, but I need to add WebSockets, and Play Framework's WebSocket interface is preferable. (We've tried Undertow, and encountered too many problems with its clunky interface)

我只能创建并启动一个应用程序，但是我无法连接到它.运行以下代码后，端口8000上没有任何监听.我需要做什么?

I've only gotten as far as creating an application, and starting it, but I'm unable to connect to it. After I run the following code, nothing is listening on port 8000. What do I need to do?

application.conf:

play.server.http.port=8000 http.port=8000

webserver.scala:

def startWebServer = { val environment = new Environment( new File("/path/to/app"), classOf[Dummy].getClassLoader, play.api.Mode.Dev ) val context = play.api.ApplicationLoader.createContext(environment) val application = ApplicationLoader(context).load(context) play.api.Play.start(application) }

build.sbt:

libraryDependencies += "com.typesafe.play" %% "play" % "2.5.0-M1"

输出:

[info] play.api.Play - Application started (Dev)

推荐答案

那只是应用程序.它仍然需要一个主机.添加以下代码:

That was just the application. It still needs a host. Add the following code:

webserver.scala:

play.core.server.NettyServer.fromApplication( application )

build.sbt:
