使用xsbt-web-plugin请求Jetty容器的登录控制台

Question

I'm using the xsbt-web-plugin to develop a webservice.

For easier debugging I would like to switch on request logs in console like the line below.

[22/Dez/2012:15:29:56 +0000] "GET /messages HTTP/1.1" 200 27276

In production I'm using NCSARequestLog which is fine, but in development I would like to include the log in my sbt console where I started the container via container:start /

How can I enable the request logs?

Answer 1

To enable request logs, you can configure an NCSARequestLog via a custom jetty.xml file.

Add this to build.sbt :

env in Compile := Some(file(".") / "jetty-env.xml" asFile)

Create myproject/jetty-env.xml :

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

  <Set name="handler">
    <New id="RequestLog" class="org.eclipse.jetty.server.handler.RequestLogHandler">
      <Set name="requestLog">
        <New id="RequestLogImpl" class="org.eclipse.jetty.server.NCSARequestLog">
          <Set name="filename"><Property name="jetty.logs" default="./logs"/>/test-yyyy_mm_dd.request.log</Set>
          <Set name="filenameDateFormat">yyyy_MM_dd</Set>
          <Set name="LogTimeZone">GMT</Set>
          <Set name="retainDays">90</Set>
          <Set name="append">true</Set>
        </New>
      </Set>
    </New>
  </Set>

</Configure>

In sbt, run container:start , and you'll see request logs collected under myproject/logs . When I tested this, Jetty would not create the logs directory on its own - I had to do that myself.

You can watch the request log in real time with tail :

tail -f myproject/logs/test-2013_08_23.request.log

For a full example of this, see the request-logging branch of xwp-template .
