CXF 客户端异常：{XXX} 的侦听器已引发异常，现在正在展开
我遇到了以下 CXF 异常：
warning: Interceptor for {http://example.com/wsdl/esc/2011-12-12/}AmazonEC2#{http://example.com/wsdl/esc/2011-12-12/}NewDescribeImages has thrown exception, unwinding now

javax.xml.ws.soap.SOAPFaultException: Fault string, and possibly fault code, not set
导致此异常的代码：
MyService ms =new MyService ();
MyServicePort port = ms.getAmazonEC2Port();
BindingProvider bp = (BindingProvider) port;
bp.getRequestContext()
.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
"http://192.180.33.12:8773/services/myservice_url/");
Client client = ClientProxy.getClient(portType);
client.getInInterceptors().add(new LoggingInInterceptor());
client.getOutInterceptors().add(new LoggingOutInterceptor());
Endpoint endpoint = client.getEndpoint();
Map<String, Object> inProps=new HashMap<String, Object>();
Map<String,Object> outProps = new HashMap<String,Object>();
configWSProps(inProps, outProps); //here is some WS-Security properties
WSS4JInInterceptor wssIn = new WSS4JInInterceptor(inProps);
WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);
endpoint.getInInterceptors().add(wssIn);
endpoint.getOutInterceptors().add(wssOut);
SomeResponseType response = port.someMethod();
此异常在最后一行中引发：port.someMethod（）。在configWSProps（...）方法中，我设置了一些WS-Security属性，它不太可能在这里出现问题。
我打印了cxf日志，我可以看到入站消息具有正确的数据。
从 CXF 源代码来看，CXF 似乎无法检索 soap 消息，但我不知道如何解决这个问题。请帮帮我！
