早上好，

我正在寻求帮助。我只是一个初学者。

我正在使用来自（DOSGi Apache Karaf 功能分布）的 cxf-dosgi

我想在两台远程机器之间透明地使用服务。所以我在这两台机器上都有一个 karaf 容器。

我测试了这个 示例：从托管在同一台机器上的两个容器 karaf 开始，然后我将配置更改为使用托管在两台不同远程机器上的两个容器进行测试。而且效果很好！

所以我想做同样的事情来导出我的网络服务。我正在使用 Spring DM。所以我在服务器端这样做：

<osgi:service id="osgi-service" ref="myservice" interface="org.apache.camel.Endpoint"> <osgi:service-properties> <entry key="name" value="service"/> <entry key="service.exported.interfaces" value="*"/> </osgi:service-properties> </osgi:service>

我使用 cxf dosgi 1.6 版进行了本教程中的安装，但出现此错误：

你知道出了什么问题吗？

哎哟..你在用 1.4-SNAPSHOT 做什么。首先它不是一个版本，其次它很旧。

另一件看起来可疑的事情是 service.exported.interfaces=myInterface。它应该是一个完全限定的 java 接口名称。首先尝试 service.exported.interfaces=* 。

您应该从我的CXF DOSGi 教程开始。那里的代码应该开箱即用。然后，您可以在配置中添加您的更改。因此，这比从头开始更容易。
