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" />
