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>
