Apache camel soap请求类型转换错误

Apache camel soap request type conversion error(Apache camel soap请求类型转换错误)

问题描述

我正在尝试在 osgi 环境 (karaf) 上运行的 apache camel 中发送一个肥皂请求.直到现在我得到了这个代码

I'm trying to send a soap request in apache camel running on an osgi enviroment (karaf). Until now I got this code

public void start(BundleContext context) throws Exception {
    LOGGER.log(Level.INFO, "START");

    MyRouteBuilder routeBuilder = new MyRouteBuilder();
    camelContext = new DefaultCamelContext();

    StreamComponent stream = new StreamComponent();
    camelContext.addComponent("stream", stream);

    camelContext.addRoutes(routeBuilder);

    CxfComponent cxf = new CxfComponent();
    camelContext.addComponent("cxf", cxf);

    try {
        ProducerTemplate template = camelContext.createProducerTemplate(0);
        camelContext.start();
        String url = "cxf://http://some.server/webservice?"
                + "wsdlURL=http://some.server/webservice?wsdl&"
                + "serviceName={http://some.server}Service&"
                + "portName={http://some.server}ServiceSoapPort"
                + "&dataFormat=MESSAGE";
        Exchange e = sendSimpleMessage(template, url);
        LOGGER.log(Level.INFO, e.getOut().getBody().toString());
    } catch (Exception e) {
        LOGGER.log(Level.SEVERE, "ERROR: ");
    }

}

public void stop(BundleContext context) {
    LOGGER.log(Level.INFO, "STOP");

    try {
        camelContext.stop();
    } catch (Exception e) {
        LOGGER.log(Level.INFO, e.toString());
    }

}

private static Exchange sendSimpleMessage(ProducerTemplate template,
        String endpointUri) {

    final List<String> params = new ArrayList<String>();
    Map<String, Object> headers = new HashMap<String, Object>();
    headers.put(CxfConstants.OPERATION_NAME, "authenticate");
    headers.put("requestObject", new DefaultCxfBinding());
    params.add("hello world");

    Exchange exchange = template.request(endpointUri, new Processor() {
        public void process(final Exchange exchange) throws Exception {
            SOAPMessage soapMessage = createSOAPRequest();

            soapMessage.setContentDescription("someId");
            soapMessage.setProperty("key", "value");
            soapMessage.setProperty("key", "value");
            soapMessage.setProperty("key", "value");

            soapMessage.setContentDescription("");
            soapMessage.setProperty("key", "value");

            exchange.getIn().setBody(soapMessage.getSOAPBody());
        }
    });
    return exchange;

}

private static SOAPMessage createSOAPRequest() throws Exception {
    MessageFactory messageFactory = MessageFactory.newInstance();
    SOAPMessage soapMessage = messageFactory.createMessage();
    SOAPPart soapPart = soapMessage.getSOAPPart();

    String serverURI = "http://some.server";

    // SOAP Envelope
    SOAPEnvelope envelope = soapPart.getEnvelope();
    envelope.addNamespaceDeclaration("", serverURI);

    javax.xml.soap.SOAPBody soapBody = envelope.getBody();
    SOAPElement soapBodyElem = soapBody.addChildElement("getApplication",
            "example");

    MimeHeaders headers = soapMessage.getMimeHeaders();
    headers.addHeader("SOAPAction", "http://some.server/someFunction");

    soapMessage.saveChanges();

    LOGGER.log(Level.INFO, soapMessage.toString());

    return soapMessage;
}

现在我的 karaf 日志中出现了这个错误

And now I got this error in my karaf logs

java.lang.IllegalArgumentExcetion: Could not find a suitable setter for property: portName as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: javax.xml.namespace.QName with value [...]

当我删除 portName 时 serviceName 也会发生同样的情况 - 那么如何将这些参数作为 javax.xml.namespace.QName 传递呢?还是我做错了什么?

And the same happens for serviceName when I delete portName - So how is it possible to pass these arguments as javax.xml.namespace.QName? Or is there anything else I'm doing wrong?

当我将它简化为这个时得到同样的错误

Getting the same error when I simplify it to this

        from("direct:start")
            .process(new Processor() {

                public void process(Exchange exchange) throws Exception {
                    exchange.getIn().setBody("<mandant>001</<mandant>");
                }
            })
            .to("cxf://http://some.server/webservice?"
            + "wsdlURL=http://some.server/webservice?wsdl&"
            + "serviceName={http://some.server}Service&"
            + "portName={http://some.server}ServiceSoapPort"
            + "&dataFormat=MESSAGE")
            .to("file:C:/output?fileName=soap.txt");

推荐答案

你需要的TypeConverter是CxfConverter 通常由 Spring 或 Blueprint 使用 AnnotationTypeConverterLoader.您可以像 this 一样将 TypeConverters 添加到 CamelContext 但它仅适用于实现 TypeConverter 接口的类，但CxfConverter 是@Converter 注解的，应该使用discovery 找到它.

The TypeConverter that you need is CxfConverter It is normally loaded to CamelContext by Spring or Blueprint using AnnotationTypeConverterLoader. You can add TypeConverters to CamelContext like this but it only works on classes that implement TypeConverter interface but CxfConverter is @Converter annotated and it should be found using discovery.

我不知道如何解决这个问题，但我希望你能进一步了解这些信息.如果你明白了，请在此处更新.

I don't know how to solve this but I hope you get further with this information. Please update here if you figure this out.
