更改Scalatra端口

Question

更改Scalatra端口

10

这听起来很基础，但实际上花费了我一整天的时间：我想在开发中更改scalatra运行的端口。我从hello world g8模板开始构建。

到目前为止我尝试过：

按照文档在build.scala中更改端口： http://www.scalatra.org/guides/deployment/configuration.html 这无法编译，因为端口没有定义。

按照这两个示例在build.scala中更改端口： https: gist.github.com dozed 58af6cfbfe721a562a48 https://github.com/JamesEarlDouglas/xsbt-web-plugin/blob/master/src/sbt-test/web/servlet/project/Build.scala 同样的问题：端口未定义

按照文档重新定义入口点： http: www.scalatra.org guides deployment standalone.html 仍然在8080端口上运行

在bootstrap文件中更改init参数，按照文档： http: www.scalatra.org guides deployment configuration.html 仍然在8080端口上运行

感谢任何帮助。由于某种原因我不能发布超过2个链接，因此请将空格替换为正斜杠以跟踪链接。

这是我的build.scala文件，如果有帮助的话。

根据文档，build.scala 的设置应该是：port in container.Configuration := 8081，但你的设置是 port in Conf := 8081。你是否尝试按照文档中指定的方式进行设置？ - cmbaxter

是的，我也尝试过那个。 - Kire321

我做了这个并且有效：

....
val port = SettingKey[Int]("port")
val Conf = config("container")

lazy val project = Project (
    port in Conf := 8081,
    ....
)

我在项目根目录下创建了一个空的build.sbt文件，并添加了以下内容： port in container.Configuration := 8090 只有这样才能使它正常工作。

Update 23.01.2016: scalatra-sbt使用xsbt-web-plugin 2.0.4，并进行了一些设置更改。您可以在此处找到xsbt-web-plugin文档（相关说明：xsbt-web-plugin、sbt-web、docker和独立构建的集成可在https://github.com/scalatra/scalatra-in-action中找到，参见chapter09-*目录）。

对于Scalatra应用程序，这意味着：

使用jetty:start和jetty:stop代替container:start和container:stop
启用JettyPlugin
使用新的键，例如containerPort in Jetty := 8090、target in webappPrepare、sourceDirectory in webappPrepare
仅限基于.scala的SBT构建定义：使用正确的导入来导入插件和设置键

一个.sbt构建定义：

organization := "org.foo"
name := "My build"
version := "0.1.0-SNAPSHOT"
scalaVersion := "2.11.6"

val ScalatraVersion = "2.4.0"

libraryDependencies ++= Seq(
  "org.scalatra" %% "scalatra" % ScalatraVersion,
  "org.scalatra" %% "scalatra-specs2" % ScalatraVersion % "test",
  "com.typesafe" % "config" % "1.2.1",
  "ch.qos.logback" % "logback-classic" % "1.1.3" % "runtime",
  "javax.servlet" % "javax.servlet-api" % "3.1.0" % "provided"
)

enablePlugins(JettyPlugin)

containerPort in Jetty := 8090

基于 .scala 的 SBT 构建定义确实魔力略少，我们需要导入插件及其设置：

import sbt._
import Keys._

import org.scalatra.sbt._

import com.earldouglas.xwp.JettyPlugin
import com.earldouglas.xwp.JettyPlugin.autoImport._
import com.earldouglas.xwp.ContainerPlugin.autoImport._

实际的构建定义是 enablePlugins(JettyPlugin)，并且使用自定义端口：

object MyBuild extends Build {
  val Organization = "org.foo"
  val Name = "My Build"
  val Version = "0.1.0-SNAPSHOT"
  val ScalaVersion = "2.11.6"
  val ScalatraVersion = "2.4.0"

  val mySettings =
    ScalatraPlugin.scalatraSettings ++ Seq(
      organization := Organization,
      name := Name,
      version := Version,
      scalaVersion := ScalaVersion,
      libraryDependencies ++= Seq(
        "org.scalatra" %% "scalatra" % ScalatraVersion,
        "org.scalatra" %% "scalatra-specs2" % ScalatraVersion % "test",
        "com.typesafe" % "config" % "1.2.1",
        "ch.qos.logback" % "logback-classic" % "1.1.3" % "runtime",
        "javax.servlet" % "javax.servlet-api" % "3.1.0" % "provided"
      ),
      containerPort in Jetty := 8090
    )

  lazy val project = Project("chapter09", file("."))
    .enablePlugins(JettyPlugin)
    .settings(mySettings: _*)

}

确保你正在使用导入:

import com.earldouglas.xsbtwebplugin.PluginKeys._
import com.earldouglas.xsbtwebplugin.WebPlugin._

通过这些导入，您可以使用正确的密钥和配置：

port in container.Configuration := 9000

这段代码放在设置块中：

...
lazy val project = Project (
  "example",
  file("."),
  settings = Defaults.defaultSettings ++ ScalatraPlugin.scalatraWithJRebel ++ scalateSettings ++ Seq(
    port in container.Configuration := 9000,
    organization := Organization,
...

scalatra-sbt是基于xsbt-web-plugin构建的，该插件的设置文档在此处：https://github.com/JamesEarlDouglas/xsbt-web-plugin/wiki/Settings
