windows:

查看端口占用(获得进程ID)

netstat -aon|findstr "31581"

查看任务端口(获得进程名称)

tasklist|findstr "4504"

结束任务

taskkill /f /t /im javaw.exe


 

linux:

netstat -tunlp|grep 18191

ps -ef|grep 23049

kill -9 tomcat

 

 

通过启动前,查看windows端口,未发现被占用,启动后占用,确定问题为spring context 初始化两次导致dubbo端口被占用。

解决方式:修改server.xml 如下

<Host name="localhost" debug="0" appBase="/data/www/ROOT/xxx"

      unpackWARs="true" autoDeploy="false" deployOnStartup="false"

      xmlValidation="false" xmlNamespaceAware="false" >

  <Context path="" docBase="xxxxx" debug="0" reloadable="false"/>

</Host>
