以下是我的网络服务请求,路由和请求验证器,

RequestValidator:

  public void validate(GetHotelMediaRQ request, Exchange exchange) throws Exception {
        TransactionContext context = BusExtensions.getTransactionContext(exchange);
        Collection<HotelRef> hotelRefList = getInstance().convert(request, Collection.class);
        Set<Property> properties = new HashSet<>();
        String customerAppId = exchange.getIn().getHeader("customerAppID", String.class);
        String customerId = exchange.getIn().getHeader("customerID", String.class);

但是当我尝试通过Exchange对象访问时,customerAppId(AppTest)和CustomerId(CI12345)将变为null。

&#34;自定义&#34; Soap标头不会复制到camel标头。你必须手动将soap标头添加到camel exchange header中。

方法1)

CamelCxfMessage - 您可以提取/处理自定义soap标头camel cxf消息,该消息存在于camel exchange header

在骆驼中 - SoapMessage soapMessage =(SoapMessage)exchange.getIn()。getHeader(&#34; CamelCxfMessage&#34; );

这将为您提供soap消息及其soapMessage.getExchange,并尝试从soap消息中获取soap标头并对其进行处理。

方法2)

Camel Cxf Binding - 您可以在端点定义中使用camel cxf绑定功能,例如cxfBinding =# bindingName

使用org.apache.camel.component.cxf.DefaultCxfBinding创建一个类并进行扩展,bean名称应为 bindingName

它有一个你必须覆盖的方法 - propagateHeadersFromCxfToCamel (camelmessage,cxfmessage,exchage)。

在这里获取您的soap标头并将其放入带有标识符的camel标头中,并在处理器中的camel exchange标头中访问标头或使用相同标识符的路由。

将org.apache.camel的日志记录设置为DEBUG,并记录标题值,您可以确定该组件是否正在删除它们。

此外,您可能正在使用cxf soap端点。请查看文档中的[relayHeaders选项说明]部分:

我必须提取标题信息,但在第一次尝试时在对象中获取null。过了一会儿我就可以把它钓掉了。这是(在处理器中):

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

    @SuppressWarnings("unchecked")
    List<SoapHeader> headers = exc.getIn().getHeader(Header.HEADER_LIST, List.class);
    for (int i=0; i < headers.size(); i++) {

        if (headers.get(i).getObject() instanceof ElementNSImpl) {
            ElementNSImpl elementNSImpl = (ElementNSImpl) headers.get(i).getObject();
            Node firstChild = elementNSImpl.getFirstChild();
            log.trace("header: name=" + elementNSImpl.getLocalName() + ", value=" + firstChild.getNodeValue());
        }
    }
