使用dataFormat作为POJO通过Camel调用Web Service时无法设置SOAP Header [英] Unable to set SOAP Header while calling Web Service through Camel using dataFormat as POJO

问题描述

我在我们的项目中使用Camel并请求WebServices，其dataFormat为POJO.当我的SOAP消息不包含SOAP标头时，我能够请求，但是当它具有标头时，我无法设置这些标头.我查看了文档，但无法理解，并有几个问题.

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.

我想创建如下消息:

<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>

如果只有Body，我将能够发送消息，但是有人可以给我包含头部分的代码段吗? dataFormat是POJO.

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.

推荐答案

使用dataFormat作为POJO的CXF端点时，Camel Exchange对象中的body是org.apache.cxf.message.MessageContentsList的对象.它是java.util.ArrayList<Object>的扩展，按WSDL中定义的顺序包含SOAP消息的各个部分，并包含WebService类中的相应方法. 元素0有一个Body.

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.

因此，使用Java的一种方法是创建一个实现org.apache.camel.Processor接口的Processor类，并在其process方法中设置您的SOAP标头.像这样:

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);

}

(未经测试的示例.这只是一个想法，如何处理...)

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

它描述了如何将Camel Exchange头用作SOAP头.

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

我不确定100％哪种方法对您有效，哪种更好... 我猜，这取决于您使用的WSDL.

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:第二选择是通过使用CxfMessageSoapHeaderOutInterceptor自定义实现来使用纯CXF解决方案. 它可能看起来像:

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);

   }

，然后将Camel Cxf端点中的拦截器"设置为:

and set Interceptor in Camel Cxf Endpoint as :

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