没有

部署到它，到目前为止唯一的变化是安装了Camel-http4，camel-jetty9和camel-mongoDB功能。

可能导致此问题的原因是什么，我该如何解决？

Answer 1

我已经找到了原因。ServiceMix 已启动，安装了功能，停止，压缩，发送到新计算机，并在不同的目录中解压缩。

通过删除以下文件夹修复了该问题

apache-servicemix-7.0.0datacachebundle3dataconfigorgapacheactivemqserver

其中包含在移动服务器后不再有效的 ActiveMQ 配置信息。

其他系统似乎也受到此影响。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。(请注意，这将擦除基本版本的所有更改(

从那以后，我继续使用 karaf-maven-plugin 来预设置服务器，并且只安装我实际使用的 servicemix 组件。
