解决方法：我报这个错是因为，tomcat的server.xml文件

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

        <!-- 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
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="/home/anshan/apache-tomcat-8.5.33/logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />i
               <Context path="/file" docBase="/home/uploadFile" reloadable="true" debug="0"></Context>
               <Context path="/file1" docBase="/home/listener_logs" reloadable="true" debug="0"></Context>
      </Host>

host标签，appBase="webapps"项目打包放在该目录下，通过tomcat访问。

Context 标签docBase="/home/uploadFile" 是静态资源页面访问，ip加tomcat端口号，加path加文件名，直接访问静态文件

我的问题就是tomcat安装完成后 没有docBase对应的文件
