错误：java.lang.ClassCastException：类org.apache.cxf.bus.spring.SpringBusFactory

你好！

我正在尝试使用 CXF 创建一个 Web 服务客户端。我的应用程序在 OSGi 中。我使用 Felix 框架。

但是出现以下错误：

我说可能是因为ClassLoader不同。可以吗？

知道如何解决这个问题吗？

谢谢！

是的，看起来您有两个 BusFactory 类定义。 SpringBusFactory 实现其中一个，而 asSubclass() 调用则对另一个进行。由于一个 BusFactory 与另一个 BusFactory 不是同一类，因此您将获得 CCE。查找包含 BusFactory 类的两个不同的包。其中之一将由定义 SpringBusFactory 的包导入。

我认为“两个 BusFactory 类定义”是一种转移注意力的说法。

不确定您使用的 CXF 版本（猜测是 2.4.2），但该代码在查找子类实现时尝试使用线程上下文类加载器执行 ServiceLoader 之类的操作。

我最好的猜测是 CXF 依赖于一些 Spring“魔法”，而您缺少提供它的捆绑包。查看 Karaf 的 CXF 功能，它有大量依赖项，请检查这一点并确保您已获得所有依赖项 - 此时，使用安装了 CXF 功能的 karaf 进行尝试可能会更容易。

如果您使用 Maven，可以通过以下方式访问功能文件：

我过去曾在 pax-exam 中看到过类似的奇怪错误。这是否在“正常”OSGi 环境中的 pax-exam 之外运行？ Talend Service Factory ( http://talend.com/products/tsf ) 有几个在 OSGi 中运行的 CXF 客户端和服务示例（在单独的示例下载包中），它们都可以正常工作。
