我遇到以下CXF异常:

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();

在最后一行抛出此异常:port.someMethod()。 在configWSProps(...)方法中,我设置了一些WS-Security属性,这里不太可能有问题。

我打印了cxf日志,我可以看到入站消息有正确的数据。

从CXF源代码中,似乎CXF无法检索soap消息,但我不知道如何解决这个问题。请帮帮我!

这是CXF源代码: http://grepcode.com/file/repo1.maven.org/maven2/org.apache.cxf/cxf-rt-bindings-soap/2.4.1/org/apache/cxf/binding/soap/interceptor/StartBodyInterceptor.java/#59

2 个答案:

答案 0 :(得分:16)

在cxf代码中调试并在cxf邮件列表中寻求帮助后,我终于解决了这个问题。 问题是由入站消息引起的,http消息缺少content-type标头,导致CXF无法创建XMLStreamReader,然后无法读取内容,因此抛出NullPointerException。 非常感谢CXF社区的人们!

我问了一个问题并在那里得到了答案: http://cxf.547215.n5.nabble.com/CXF-client-exception-Interceptor-for-XXX-has-thrown-exception-unwinding-now-td5449373.html#a5449764

答案 1 :(得分:0)

确保端点正确或可通过已部署组件的环境访问。

可能是没有通过端点的代理问题。
