Question

早上好,

我在找人帮忙，我只是个初学者。

我正在使用cxf-dosgi (DOSGi Apache Karaf特性分发版)。

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卡夫容器。

我测试了这个示例：首先从托管在同一台机器上的两个容器开始，然后将配置更改为使用两个托管在两台不同远程机器上的容器进行测试。而且效果很好！

所以我想做同样的事情来导出我的web服务。我正在使用Spring。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版本1.6进行了类似于教程中的安装，但我得到了以下错误：

你知道怎么回事吗？

Answer 1

哎哟。你在用1.4快照做什么？第一，它不是发行版，第二，它是相当古老的。

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，请尝试使用service.exported.interfaces=*。

你应该从我的CXF DOSGi教程开始。那里的代码应该是开箱即用的。然后，可以在配置中添加更改。因此，这比开始全新的更容易。
