没有任何部署到它，到目前为止唯一的变化是已经安装了camel-http4，camel-jetty9和camel-mongodb功能。

可能导致此问题的原因以及如何解决？

Answer 1

我已经找到了原因。 ServiceMix已启动，已安装，停止，压缩，发送到新计算机，并在其他目录中解压缩。

通过删除以下文件夹

解决了该问题

apache-servicemix-7.0.0\data\cache\bundle3\data\config\org\apache\activemq\server

其中包含在移动服务器后不再有效的ActiveMQ配置信息。

其他系统似乎也受此影响。修复它的正确方法似乎是在karaf离线时删除数据目录，或者使用clean标志启动karaf。（注意，这将擦除基本版本中的所有更改）

我已经开始使用karaf-maven-plugin来预先设置服务器，并且只安装我实际使用的servicemix组件。

amq-broker无法在ServiceMix中启动
