在host节点下添加 Context 节点，如下：
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log" suffix=".txt"
pattern="%h %l %u %t "%r" %s %b" />
<Context docBase="E:\work\v4.0.0.0\web" path="/vpn11" reloadable="true" />
</Host>
