当我开始我的卡拉夫时，我有一种奇怪的行为。
我的JAR包包含一个简单的camel spring xml路由，它将传入的xml片段转换为带有xslt的文本。我使用BridgePropertyPlaceholderConfigurer将我的属性外部化为{karaf.base} /etc/karaf-invalid-bundle.cfg。
为了说明我的帖子，我创建了一个github存储库https://github.com/johanlelan/Karaf-invalid-bundle-example。
偶尔，我的捆绑包无法为一个奇怪的原因启动：

我认为此错误与我的属性或我的BundleActivator类相关联。 关于阻止这种行为的任何想法？

答案 0 :(得分：0)
在春天不确定你的具体问题。我很久以前就停止在OSGi上使用spring了。
更简单的解决方案是使用蓝图而不是弹簧。然后，您可以使用蓝图的配置管理支持附加到配置文件等.BLueprint在OSGi中比spring dm运行得更顺畅。
您还可以获得蓝图配置的配置管理属性自动作为camel属性使用的优势。
