更改Scalatra端口

Question

这听起来很基本，但实际上花了我一整天的时间:我想更改正在开发中的scalatra运行端口。我从hello world g8模板开始，并一直从那里开始构建。

这是我到目前为止尝试过的：

更改build.scala中的端口，ala文档：http://www.scalatra.org/guides/deployment/configuration.html这不能编译，因为端口未定义。

更改build.scala中的端口这两个示例: 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

重新定义入口点，ala http: www.scalatra.org指南部署standalone.html仍然在端口8080上运行

更改引导程序中的初始化参数，ala http: www.scalatra.org指南部署configuration.html仍然在端口8080上运行

感谢您的帮助。由于某些原因，我不能发布超过2个链接，所以请在urls后面用正斜杠替换空格。

这是我的build.scala，如果有帮助的话。

Answer 1

更新23.01.2016：scalatra-sbt使用xsbt-web-plugin 2.0.4，并更改了一些设置。你可以找到xsbt-web- here文档(相关注释:可以在https://github.com/scalatra/scalatra-in-action中找到xsbt-web-plugin，sbt-web，docker和独立版本的集成，参见09-*章目录)。

对于Scalatra应用程序，这意味着：

基于sourceDirectory in webappPrepare

• only的构建定义:使用正确的导入来导入插件和设置密钥

.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构建定义没有那么神奇，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._

使用enablePlugins(JettyPlugin)和自定义端口的实际构建定义：

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: _*)

}

确保您使用的是导入：

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

这将放在settings块中：

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

scalatra-sbt构建在xsbt-web-plugin上，其设置记录在这里：https://github.com/JamesEarlDouglas/xsbt-web-plugin/wiki/Settings

Answer 2

我这样做了，并且工作了：

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

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

Answer 3

我在项目的根目录下创建了一个空的build.sbt文件，并放入：

port in container.Configuration := 8090

在文件中才能正常工作。
