tomcat修改端口,idea生成jar文件

⒈tomcat修改端口, 需要改动tomcat/conf/server.xml中3个地方的端口

<Server port="8005" shutdown="SHUTDOWN">

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

⒉idea中单文件class生成jar文件

　　

　　

　　

⒊jar文件放到tomcat/下就可以执行

⒋java原生操作dom小例子
