tomcat更改端口号

<Service name="Catalina1">

//端口9001

<Connector port="9001" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
 
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

<Engine name="Catalina1" defaultHost="localhost">

<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>

//访问地址appBase
      <Host name="localhost"  appBase="webapps/ld"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

</Host>
    </Engine>
  </Service>

就是不知道为什么改了端口号，ajax提交不了地址错误?

//localhost访问

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
