在tomcat下conf的sever.xml中 找到

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

        <!-- 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 -->
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" 
               prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
        -->

<Context path="/wyz" docBase="D:\work space\wyz"  reloadable="true"  >
</Context>

      </Host>

在其中加入

<Context path="/虚拟路径名" docBase="应用程序实际地址"  reloadable="true"  >
</Context>即可
