win下ActiveMQ启动报错：BeanFactory not initialized or already closed - call 'refresh' before ...

win下安装ActiveMQ：

官网下载：

本地解压：

进入bin/，根据自己电脑，选择win32/win64，点击activemq.bat 即可运行。

启动错误：

ERROR: java.lang.RuntimeException: Failed to execute start task. 
Reason: 
java.lang.IllegalStateException: BeanFactory not initialized or already closed 
- call 'refresh' before accessing beans via the ApplicationContext

jvm 1    | java.lang.RuntimeException: Failed to execute start task. 
Reason: java.lang.IllegalStateException: 
BeanFactory not initialized or already closed 
- call 'refresh' before accessing beans via the ApplicationContext

接着向上翻，看有没有更具体地提示：

ERROR | Failed to start Apache ActiveMQ (localhost, ID:DESKTOP-31JCR4J-55998-1557803455731-0:1)
jvm 1    | java.io.IOException: 
Transport Connector could not be registered in JMX: 
java.io.IOException: 
Failed to bind to server socket: 
amqp://0.0.0.0:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600 
due to: java.net.BindException: Address already in use: JVM_Bind

看到这里，应该是5672端口被占用了。

查看5672被谁占用：netstat -aon | findstr "5672"

输入命令：tasklist | findstr "4240" 查找具体的占用进程

打开资源管理器，找到PID是4240的进程（没有PID这一列的话可以右击列添加PID列）

这个进程暂时也没啥用，直接结束它。

重新启动ActiveMQ。

启动成功！
