Unable to set SOAP Header while calling Web Service through Camel using dataFormat as POJO

问题

I am using Camel in our project and requesting WebServices, the dataFormat is POJO. I was able to request when my SOAP message did not contain SOAP headers, but when it had Headers, I was unable to set those. I looked at the documentation but was not able to understand and have several questions.

I want to create a message like the below:

<soapenv:Envelope`enter code here`
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Header>
        <platformMsgs:documentInfo
            xmlns:platformMsgs="urn:messages_2015_1.platform.webservices.netsuite.com">
            <platformMsgs:nsId>WEBSERVICES_3479023</platformMsgs:nsId>
        </platformMsgs:documentInfo>
    </soapenv:Header>
    <soapenv:Body>
        <addListResponse
            xmlns="">
            <platformMsgs:writeResponseList
                xmlns:platformMsgs="urn:messages_2015_1.platform.webservices.netsuite.com">
                <platformCore:status isSuccess="true"
                    xmlns:platformCore="urn:core_2015_1.platform.webservices.netsuite.com"/>
                    <platformMsgs:writeResponse>
                        <platformCore:status isSuccess="false"
                            xmlns:platformCore="urn:core_2015_1.platform.webservices.netsuite.com">
                            <platformCore:statusDetail type="ERROR">
                                <platformCore:code>DUP_ENTITY</platformCore:code>
                                <platformCore:message>This entity already exists.</platformCore:message>
                            </platformCore:statusDetail>
                        </platformCore:status>
                    </platformMsgs:writeResponse>
                </platformMsgs:writeResponseList>
            </addListResponse>`enter code here`
        </soapenv:Body>
    </soapenv:Envelope>

I will be able to send the message if there was only Body, but can someone give me a code snippet for including the header section? The dataFormat is POJO.

回答1:

When using CXF endpoint with dataFormat as POJO, body in Camel Exchange object is an object of org.apache.cxf.message.MessageContentsList. It is an extension of java.util.ArrayList<Object> and it contains parts of SOAP Message in order as defined in WSDL and corresponding method in WebService class. Element 0 there is a Body.

So, one way to do that with Java is to create a Processor class implementing org.apache.camel.Processor interface and in its process method set your SOAP header. Something like:

@Override
public void process(Exchange camelExchange) throws Exception {

  MessageContentsList messageBody = (MessageContentsList) camelExchange.getIn().getBody(); 

   DocumentInfo docInfoHeader = new DocumentInfo();
   ... set docInfoHeader properties ...
   messageBody.add(docInfoHeader);

}

(sample is not tested. It is just an idea, how to handle that...)

Other answer on similar question you can find here: Setting Custom Soap Header-To Pojo Message In Camel Cxf

It describes how to use Camel Exchange headers as SOAP Headers.

I'm not sure for 100% which way will work for you and which one is better... I guess, it depends on WSDL you use.

UPD: second choice is to use pure CXF solution by using CxfMessageSoapHeaderOutInterceptor custom implementation. It may look like:

public class MyCxfInterceptor extends CxfMessageSoapHeaderOutInterceptor {
   @Override
   public void handleMessage( org.apache.cxf.binding.soap.SoapMessage message) {

      org.apache.cxf.binding.soap.SoapHeader myCustomHeader = new org.apache.cxf.binding.soap.SoapHeader(new QName(
                {custom name space}, {custom local name}), {Custom content object}));

        myCustomHeader.setMustUnderstand(true);

        message.getHeaders().add(myCustomHeader);

   }

and set Interceptor in Camel Cxf Endpoint as :

<cxfEndpoint ...>
    <outInterceptors>
        <spring:bean class="MyCxfInterceptor"/>
    </outInterceptors>
...

回答2:

Well suppose I request the Web Service and it failed, a Fault message is generated. Will I get the Fault object at position 0 of MessageContentsList then too? Or will I get only the response object at position 0?
