解决：

找到tomcat的server.xml文件，找到下面一段

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

      </Host>

替换

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

      </Host>
