Caused by: java.net.BindException: Address already in use: JVM_Bind（ActiveMq已經啟動）

1.本地啟動項目開啟兩個啟動類出錯。

Error creating bean with name 'brokerService' defined in class path resource
[com/dfocus/meeting/framework/config/mq/ActiveMQConfig.class]: 
Bean instantiation via factory method failed; 
nested exception is org.springframework.beans.BeanInstantiationException: 
Failed to instantiate [org.apache.activemq.broker.BrokerService]: 
Factory method 'brokerService' threw exception; 
nested exception is java.io.IOException: Failed to bind to server socket:
tcp://localhost:61616 due to: java.net.BindException: Address already in use: JVM_Bind
           

由于項目使用了内置的ActiveMq，第一個啟動類啟動成功，内置ActiveMq也啟動了。啟動第二個啟動類時，ActiveMq正在啟動中，是以報錯。

2.解決方法

1.在第二個啟動類修改ActiveMq端口号，啟動一個新的内置ActiveMq。

2.使用外部部署的ActiveMq伺服器。
