为什么在我的 CXF 和 Spring 配置中抛出异常现在展开 org.apache.cxf.interceptor.Fault
why in my CXF and Spring configuration throwning exception unwinding now org.apache.cxf.interceptor.Fault
我正在使用 CXF + Spring 公开 Soap Web 服务，当我通过 SoapUi 调用时，我得到
Application {http://art/}VmxServiceImplService#{http://art/}getV has thrown exception, unwinding now
org.apache.cxf.interceptor.Fault
深入查看我的代码，我可以看到服务实现启动了两次：第一次我确实看到了可用的模拟，第二次我看到它为空。第一次对应于我部署应用程序并首次调用它。在这种情况下，setVmxMock 中的中断点清楚地显示 vmxMock 已填充。第二次和任何进一步的调用显示 vmxMock 为空。
我记得我在使用 Spring MVC 时遇到过类似的问题，但事实并非如此。在那种情况下，我通过更改 web.xml
来修复
<servlet-name>Servlet-plus-any-word</servlet-name>
不幸的是，同样的方法不适用于 CXFServlet。
我想问题是我缺少将 ContextLoaderListener 与 CXFServlet 分开的某些技巧，但我不知道该怎么做。所以，我的直截了当的问题是：我的 CXF 和 Spring 如此简单的 Web 服务设置有什么问题？

因此，CXF 在启动 jax-ws 端点时会创建 art.VmxServiceImpl 的新实例。在这个新实例中，vmxMock 为空且
return this.vmxMock.getVm();
导致堆栈跟踪的主要错误

您提供的是 class 名称，而不是参考。请参阅 JAX-WS configuration 中对 implementor 属性的描述。
The implementor of jaxws endpoint. You can specify the implementor class name here, or just the ref bean name in the format of "#REF_BEAN_NAME"
因此，CXF 在启动 jax-ws 端点时会创建 art.VmxServiceImpl 的新实例。在这个新实例中，vmxMock 为空且
return this.vmxMock.getVm();
导致堆栈跟踪的主要错误
Caused by: java.lang.NullPointerException
at art.VmxServiceImpl.getV(VmxServiceImpl.java:25)
