端口占用 java.net.BindException: Address already in use: JVM_Bind

报错 java.net.BindException: Address already in use: JVM_Bind ，端口号以绑定，表示端口占用，

 org.apache.catalina.core.StandardServer await

解决方案： 把打开的tomcat关闭重启即可，或者进入tomcat安装目录的bin文件夹下的shutdown.bat关闭即可重新使用。
1.先用命令 netstat -ano 看一下各个端口占用和进程PID(8080端口是被3296占用) 。 
2.然后在任务管理器里，查看进程。(注意：默认情况下，进程的PID是不显示的，你在菜单的查看->选择列里可以选上PID来显示) 
 

最后提醒一下，使用netstat 命令查看端口号时，查看的是Local Address 列的端口号。
