在tomcat里为多个应用配置不同的访问端口

打开tomcat安装目录，查看conf/server.xml

<?xml version="1.0" encoding="UTF-8"?><Server port="8005" shutdown="SHUTDOWN">  <Listener className="org.apache.catalina.core.AprLifecycleListener" />  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" />  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />  <Listener className="org.apache.catalina.storeconfig.StoreConfigLifecycleListener"/>  <GlobalNamingResources>    <Environment name="simpleValue" type="java.lang.Integer" value="30"/>    <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" />  </GlobalNamingResources>  <Service name="Catalina">     <!--注意：修改<Connector>里面的port -->    <Connector port="8099" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" />    <Connector port="8009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />    <Engine name="Catalina" defaultHost="localhost">      <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>      <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">      <!--注意：配置应用项目的web目录路径 -->      <Context path="/demo2" docBase="D:/java/projects/demo2/WebRoot" reloadable="true" />      </Host>    </Engine>  </Service>  </Server>增加一个应用并设置访问端口为8098<Service name="Catalina1">    <!--注意：修改<Connector>里面的port -->    <Connector port="8098" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" />    <Connector port="8009" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />    <Engine name="Catalina1" defaultHost="localhost">      <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>      <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">     <!--注意：配置应用项目的web目录路径 -->     <Context path="/demo1" docBase="D:/java/projects/demo1/WebRoot" reloadable="true" />      </Host>    </Engine>  </Service>

启动tomcat可以按如下地址访问：

http://localhost:8099/demo2/index.jsp

http://localhost:8098/demo1/index.jsp

※打注意的地方是要改的地方，另外2个应用里都存在 appBase=“webapps”，这个是tomcat下默认的目录，此目录下的所有应用均可以用这2个端口（8099、8098）访问，如果不想被2个端口都可以访问，可以修改appBase，如：appBase=”webapps2”,但要在tomcat安装目录下新建一个webapps2的目录。
