Scala 我如何拥有sbt'；s Jetty是否使用本地域名？

我想让

sbt>~Jetty

发布的Jetty版本收听

my.name.local

，我在

/etc/hosts

中将其设置为

127.0.0.1

。在sbt内更改Jetty的设置是必要的

以下是我为我的项目准备的：

import sbt._

class LiftProject(info: ProjectInfo) extends DefaultWebProject(info) {
  // ...

  val jetty = "org.eclipse.jetty" % "jetty-webapp" % "7.3.0.v20110203" % "test"

  override lazy val jettyInstance = new JettyRunner(customJettyConfiguration) 

  def customJettyConfiguration = { 
    val myLog = log 
    val myJettyClasspath = jettyClasspath 
    val myScanDirectories = scanDirectories
    val myScanInterval = scanInterval

    new CustomJettyConfiguration { 
      def classpath = jettyRunClasspath
      def jettyClasspath = myJettyClasspath
      def war = jettyWebappPath
      def contextPath = jettyContextPath
      def classpathName = "test"
      def parentLoader = buildScalaInstance.loader
      def scanDirectories = Path.getFiles(myScanDirectories).toSeq
      def scanInterval = myScanInterval
      def port = jettyPort
      def log = myLog      
      override def jettyConfigurationXML = 
        <Configure class="org.eclipse.jetty.webapp.WebAppContext">
          <Set name="virtualHosts">
            <Array type="java.lang.String">
              <Item>my.name.local</Item>
            </Array>
          </Set>
        </Configure>
    }
  }
}

导入sbt_
类LiftProject（info:ProjectInfo）扩展了DefaultWebProject（info）{
// ...
val jetty=“org.eclipse.jetty”%”jetty webapp“%”7.3.0.v20110203“%”测试
override lazy val jettyInstance=新JettyRunner（customJettyConfiguration）
def customJettyConfiguration={
val myLog=log
val myJettyClasspath=jettyClasspath
val myScanDirectories=scanDirectories
val myScanInterval=扫描间隔
新的CustomJettyConfiguration{
def classpath=jettyRunClasspath
def jettyClasspath=myJettyClasspath
def war=jettyWebappPath
def contextPath=jettyContextPath
def classpathName=“测试”
def parentLoader=buildScalaInstance.loader
def scanDirectories=Path.getFiles（myScanDirectories）.toSeq
def scanInterval=myScanInterval
def端口=jettyPort
def log=myLog
覆盖def JettyConfiguration XML=
我的名字，本地人
}
}
}

虽然它似乎毫无怨言地启动，但就我所知，访问

my.name.local

并没有击中Jetty。

我发布得太快了。我需要做的就是覆盖jettyPort：

override def jettyPort = 80

---

并通过

sudo

运行

sbt

，而不是以root身份运行sbt（危险），我个人更喜欢在Linux上使用iptables将端口80重新路由到8080：

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

它只在下次重新启动之前有效。为了在Ubuntu 10.04上保持设置，我使用：

sudo bash -c "iptables-save > /etc/iptables.rules"
echo "#!/bin/sh
iptables-restore < /etc/iptables.rules
exit 0
" > /etc/network/if-pre-up.d/iptablesload
echo "#!/bin/sh
iptables-save -c > /etc/iptables.rules
if [ -f /etc/iptables.downrules ]; then
   iptables-restore < /etc/iptables.downrules
fi
exit 0
" > /etc/network/if-post-down.d/iptablessave
chmod +x /etc/network/if-post-down.d/iptablessave
chmod +x /etc/network/if-pre-up.d/iptablesload

sudobash-c“iptables保存>/etc/iptables.rules”
回声“#！/bin/sh
iptables还原/etc/network/if-pre-up.d/iptablesload
回声“#！/bin/sh
iptables保存-c>/etc/iptables.rules
如果[-f/etc/iptables.downlaules]；则
iptables还原/etc/network/if-post-down.d/iptablessave
chmod+x/etc/network/if-post-down.d/iptablessave
chmod+x/etc/network/if-pre-up.d/iptablesload

很好，这比我的解决方案要好。因为我使用的是OS X，所以看起来这个程序名为

ipfw
