      <httpConnector>

       <port>8080</port>

      </httpConnector>

       <!--每隔多少秒检测一次改动-->

      <scanIntervalSeconds>0</scanIntervalSeconds>

      <sessionHandler implementation="org.eclipse.jetty.server.session.SessionHandler">

       <sessionManager

        implementation="org.eclipse.jetty.server.session.HashSessionManager">

        <!-- 用于存放持久化的session路径 -->

        <storeDirectory>doc/jetty-sessions</storeDirectory>
