无法确定BusFactory实现类名：java.lang.ClassCastException: class org.apache.cxf.bus.spring.SpringBusFactory

问题描述 投票：0回答：1

我尝试了一切方法来避免 JBoss cxf 加载 jboss-deployment-struct.xml 中的以下配置。 

<jboss-deployment-structure>  
    <deployment>  
         <exclude-subsystems>
            <subsystem name="webservices" /> 
        </exclude-subsystems>
    </deployment> 
</jboss-deployment-structure>

我的代码在这部分失败：它不是一个maven项目，所有的jar都在lib文件夹和动态web项目下。我使用上面的配置告诉JBoss使用我的Jars，但看起来仍然使用JBoss jars。我我也在 eclipse 的 lib 文件夹下使用 JBossEAP7 和 cxf2.1.3 jar。有什么想法吗？

    SOAPConnection soapConnection = SOAPConnectionFactory.newInstance().createConnection();
    SOAPMessage response = soapConnection.call(request, endpointUrl);

查看 

BusFactory
类的源代码（下面的 v3.4.10），尝试将 
SpringBusFactory
转换为基类 
BusFactory
时会引发异常。 
SpringBusFactory
确实扩展了抽象 
BusFactory
，但对 
isAssignableFrom
的调用仍然失败。为什么？最有可能的原因是基类 
BusFactory
和 
SpringBusFactory
是由不同的类加载器加载的。 至少在我的例子中，这个问题的一个实际解决方案是更改项目的 POM 文件，以将 
cxf-*
依赖项范围缩小为 
provided
。 这从应用程序的 lib 目录（在我的例子中是 EAR）中删除了 CXF jar，并解决了眼前的问题 - 应用程序成功启动。但需要注意的是：在调试中，我什至不再看到 JBoss (WildFly v26) 尝试实例化 
SpringBusFactory
类。相反，实例化了一个不同的 JBoss 
BusFactory
实现。这可能是一件好事，意味着现在只有一个 BusFactory 实例为应用程序提供服务，但在实际访问 CXF 类时也可能会带来麻烦（在我的情况下该部分尚未测试）。

        try {
        Class<? extends BusFactory> busFactoryClass = ClassLoaderUtils.loadClass(className, BusFactory.class)
            .asSubclass(BusFactory.class);

        return busFactoryClass.getConstructor().newInstance();
    } catch (Exception ex) {
        LogUtils.log(LOG, Level.SEVERE, "BUS_FACTORY_INSTANTIATION_EXC", ex);
        throw new RuntimeException(ex);
    }
