Jettyを組み込んだall in one jarを作成する

備忘録。細かいところで過不足あるかも。

sbt

sbt-assemblyプラグインを指定

plugins.sbt

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.10.2")

ビルド定義ではJettyを依存ライブラリに追加して、sbt-assemblyの設定

build.sbt

import sbtassembly.Plugin._
import AssemblyKeys._

libraryDependencies ++= Seq(
  "org.eclipse.jetty" % "jetty-webapp" % "8.1.8.v20121106" % "compile;container",
  "org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" % "compile;container;provided;test" artifacts (Artifact("javax.servlet", "jar", "jar")))

assemblySettings

jarName in assembly := "xxx.jar"

mainClass in assembly := Some("JettyLauncher")

assemblyOption in assembly ~= { _.copy(includeScala = true) }

アプリ

Basic認証つきのランチャobjectを作成する。

JettyLauncher

object JettyLauncher {
  def main(args: Array[String]) {
    val server = new Server(8080)
    val context = new WebAppContext()
    context setContextPath "/"
    context.setResourceBase("/src/main/webapp")
    // ↓scalatra前提
    context.addEventListener(new ScalatraListener)
    context.addServlet(classOf[DefaultServlet], "/")
    context.addServlet(new ServletHolder(new MyDefaultServlet), "/css/*")

    val securityHandler = new ConstraintSecurityHandler()
    val constraint = new Constraint()
    constraint.setName(Constraint.__BASIC_AUTH)
    constraint.setRoles(Array[String]("user"))
    constraint.setAuthenticate(true)
    // mappings
    val mapping = new ConstraintMapping()
    mapping.setPathSpec("/")
    mapping.setConstraint(constraint)
    securityHandler.setConstraintMappings(Array[ConstraintMapping](mapping))
    // login service
    val loginService = new HashLoginService()
    loginService.putUser("XXX", new Password("yyy"), Array[String]("user"))
    securityHandler.setLoginService(loginService)
    // authenticator
    val authenticator = new BasicAuthenticator()
    securityHandler.setAuthenticator(authenticator)
    // set Security
    context.setSecurityHandler(securityHandler)

    server.setHandler(context)

    server.start
    server.join
  }
}

class MyDefaultServlet extends DefaultServlet {
  override def getResource(resourceString: String): Resource =
    {
      val url = this.getClass().getResource(resourceString)
      Resource.newResource(url)
    }
}
