Spring WS Integration测试SoapEnvelopeMessageCreator有效负载为null，但与PayloadMessageCreator一起提供

Question

我需要使用给定的SoapAction和Message测试Soap Server。

public class SoapActionCreator implements RequestCreator {

private final Source payload;
private final String soapAction;

public SoapActionCreator(Source payload, String soapAction) {
    this.payload = payload;
    this.soapAction = soapAction;
}

@Override
public WebServiceMessage createRequest(WebServiceMessageFactory webServiceMessageFactory) throws IOException {
    WebServiceMessage webServiceMessage =
            new SoapEnvelopeMessageCreator(payload).createMessage(webServiceMessageFactory);

    SoapMessage soapMessage = (SoapMessage) webServiceMessage;
    soapMessage.setSoapAction(soapAction);

    return webServiceMessage;
}

}

在测试方法中：

mockClient = MockWebServiceClient.createClient(applicationContext);
Source requestPayload = new StringSource(
        "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\r\n"
        + "  <soap:Body>\r\n" + */"    <Login xmlns=\"http://www.nightfreight.com/webservices\">\r\n"
        + "      <username>local_user</username>\r\n"
        + "    </Login>\r\n"
        + "  </soap:Body>\r\n" + "</soap:Envelope>");

mockClient.sendRequest(new SoapActionCreator(requestPayload, 
soapAction)).andExpect.....

由于有效载荷（方法调用中@RequestPayload标为param）为null，因此调用TestMethod时获取NullPointerException。 拦截时：messageContext.getRequest（）。getPayloadSource（）为“空”

但是在实际调用SoapService时：     messageContext.getRequest（）。getPayloadSource（）是javax.xml.transform.dom.DOMSource@1237e0be

如果在删除消息的肥皂信封部分之后使用PayloadMessageCreator而不是SoapEnvelopeMessageCreator，它将再次起作用。我将需要具有自定义名称空间以及标头，因此PayloadMessageCreator在这种情况下将无用。
