After tomcat is deployed, it cannot be accessed through IP

Problem:
After TOMCAT is deployed, the service cannot be accessed locally through IP

Analysis :
It can be accessed through the domain name For
example :
      <Host name="test.com" appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Context path="/" docBase="xxx" reloadable="true" >
        </Context>
      </Host>
      get test.com/index.jps

Solution:
      replace test.com with IP, as follows (the specific reasons will be analyzed later)
      <Host name="xxx.xxx.xxx.xxx" appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Context path="/" docBase="xxx" reloadable="true" >
        < /Context>
      </Host>
