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>
