spring - 向 SOAP 消息添加 header 元素

Question

我正在尝试寻找一种方法来将 header 元素添加到 SOAP 消息中。如果我使用 @WebParam与 header设置为 true然后它工作正常，该参数很好地在 <soap:header> 中.但是，这需要向我的 API 添加一堆参数，这几乎不是一个选项。

乍一看， View 拦截器似乎是不可能的，所以我查看了 SOAPHandlers，但很难找到关于它的明确信息。

这是我的 Spring 配置:

<bean id="testWebservice" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean" >
    <property name="serviceInterface" value="com...TestWebService"/>
    <property name="wsdlDocumentUrl" value="http://localhost:9062/test-ws/remoting/test?wsdl"/>
    <property name="serviceName" value="TestWebService"/>
    <property name="namespaceUri" value="http://test.com"/>
    <property name="portName" value="TestServicePort"/>
    <property name="lookupServiceOnStartup" value="false"/>
    <property name="handlerResolver" ref="myResolver"/>
</bean>

<bean id="myResolver" class="com...TestHandlerResolver" />

我的处理程序(链接在 TestHandlerResolver 中):

public class TestHandler implements SOAPHandler<SOAPMessageContext> {

    @Override
    public void close(MessageContext context) {
    }

    @Override
    public Set<QName> getHeaders() {
        return null;
    }

    @Override
    public boolean handleFault(SOAPMessageContext context) {
        return true;
    }

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        if (Boolean.TRUE.equals(context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY))) {

            try {
                List<Header> headers = new ArrayList<Header>();
                Header dummyHeader;
                dummyHeader = new Header(new QName("dummy"), "decapitated", new JAXBDataBinding(String.class));
                headers.add(dummyHeader);
                context.put(Header.HEADER_LIST, headers);
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
        return true;
    }
}

问题是我有点不知所措。使用处理程序是执行此操作的正确方法吗？如果是这样，您能否提供或指出一个很好的示例？有没有办法用拦截器来做到这一点？还是我完全是这里的目标...

让它像这样工作:

     @Override
     public boolean handleMessage(SOAPMessageContext context) {

            try {
                SOAPMessage msg = context.getMessage();
                SOAPPart part = msg.getSOAPPart();
                SOAPEnvelope envelope = part.getEnvelope();

                SOAPHeader header = envelope.getHeader();

                if (Boolean.TRUE.equals(context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY))) {
                    if (header == null) {
                        header = envelope.addHeader();
                    }
                    this.addToHeader(envelope, header, "MessageID", UUID.randomUUID().toString());
    ...
                } else {
                    if (header != null) {
                        Iterator<?> i = header.getChildElements();
                        while (i.hasNext()) {
                            SOAPElement el = (SOAPElement) i.next();
                            String tagName = el.getLocalName();
                            String value = el.getValue();
    ...
                        }
                    }

                }
            } catch (Exception e) {
...

            }
            return true;
        }

        private void addToHeader(SOAPEnvelope envelope, SOAPHeader header, String key, String value) throws SOAPException {
            Name qname = envelope.createName(key, "ns1", "http://ecom.bnpp.com");
            SOAPHeaderElement element = header.addHeaderElement(qname);
            element.addTextNode(value);
        }
