我正在使用CXF + Spring来公开Soap Web服务，当我通过SoapUi调用时，我得到了
Application {http://art/}VmxServiceImplService#{http://art/}getV has thrown exception, unwinding now
org.apache.cxf.interceptor.Fault
深入了解我的代码，我可以看到服务实现启动了两次：第一次看到模拟可用，第二次看到它为null。第一次对应我部署应用程序并首次唤起它时。在这种情况下，setVmxMock中的breack点清楚地显示了vmxMock填充。第二个和任何进一步的调用显示vmxMock为null。
当我使用Spring MVC时，我还是遇到了类似的问题，但事实并非如此。在这种情况下，我修改了web.xml
<servlet-name>Servlet-plus-any-word</servlet-name>
不幸的是，同样的方法不适用于CXFServlet。
我想问题是我错过了将ContextLoaderListener与CXFServlet分开的某些技巧，但我不知道该怎么做。所以，我直截了当的问题是：我的CXF和Spring设置错误，这样简单的Web服务？
服务接口：
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface VmxService {
@WebMethod
public VmxModel getV();
}
服务实施
//import javax.jws.WebService;
//@WebService(endpointInterface = "art.VmxService", serviceName = "vmxService")
public class VmxServiceImpl implements VmxService {
private VmxMock vmxMock;
public VmxServiceImpl() {
}
public void setVmxMock(VmxMock m) {
this.vmxMock = m;
}
@Override
public VmxModel getV() {
return this.vmxMock.getVm();
}
}
型号：
import java.io.Serializable;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "VmxModel")
public class VmxModel implements Serializable {
private static final long serialVersionUID = 1L;
private String retorno;
public VmxModel() {
System.out.println();
}
public String getRetorno() {
return retorno;
}
public void setRetorno(String s) {
retorno = s;
}
}
模拟
public class VmxMock {
VmxModel vm = new VmxModel();
public VmxMock(){
this.vm.setRetorno("retorno");
}
public VmxModel getVm(){
return vm;
}
}

更改
<jaxws:endpoint id="vmxService" implementor="art.VmxServiceImpl" address="/VmxService" />
与
<jaxws:endpoint id="vmxService" implementor="#vmxServiceImpl" address="/VmxService" />
您提供的是班级名称，而不是参考。请参阅JAX-WS configuration处implementor属性的说明。
jaxws端点的实现者。您可以在此处指定实现者类名，或者仅以＆＃34;＃REF_BEAN_NAME＆＃34;
的格式指定ref bean名称
因为这样，当启动jax-ws端点时，CXF正在创建art.VmxServiceImpl的新实例。在这个新实例中，vmxMock为null且
return this.vmxMock.getVm();
导致堆栈跟踪的主要错误
