由于在Tomcat中的server.xml中加了一个：
<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true"></Host> 而自身本来自带一个：<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true"></Host>
有两个Host导致重复
3、解决办法
去掉添加的一个Host
<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true"></Host>
