配置tomcat下war包可以自壓縮

      <Host name="localhost"  appBase="/home/hark/web"
            unpackWARs="true" autoDeploy="true">

        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->

        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" resolveHosts="false"/>
        <Context path="" docBase="/home/hark/web" reloadable="true" crossContext="true"/>
      </Host>

之前配置 tomcat后，發現部署war包后不會進行解壓縮，原因是因為我只配置了Context節點的docBase，應該把Host節點的appBase也指向你的站點中。
