wsdl设置请求头

要在WSDL中设置请求头，可以使用SOAP拦截器或自定义SOAP处理程序来实现。

首先，创建一个实现javax.xml.ws.handler.soap.SOAPHandler接口的类，该类将用于设置请求头。在该类中，可以通过实现handleMessage方法来添加所需的请求头。

import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPHeaderElement;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
import java.util.Set;

public class HeaderHandler implements SOAPHandler<SOAPMessageContext> {

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

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        Boolean isOutbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

        if (isOutbound) {
            try {
                SOAPMessage soapMessage = context.getMessage();
                SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope();
                SOAPFactory soapFactory = SOAPFactory.newInstance();
                String namespaceURI = "http://example.com/"; // 设置命名空间URI
                String prefix = "ns"; // 设置命名空间前缀

                SOAPHeader soapHeader = soapEnvelope.getHeader();
                if (soapHeader == null) {
                    soapHeader = soapEnvelope.addHeader();
                }

                // 创建请求头元素
                SOAPHeaderElement headerElement = soapHeader.addHeaderElement(new QName(namespaceURI, "HeaderElement", prefix));
                SOAPElement childElement = soapFactory.createElement("ChildElement", prefix, namespaceURI);
                childElement.addTextNode("Header value");
                headerElement.addChildElement(childElement);
                soapMessage.saveChanges();

            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        return true;
    }

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

    @Override
    public void close(MessageContext context) {

    }
}

然后，将该SOAP处理程序与您的客户端代码中的服务关联起来。可以使用javax.xml.ws.BindingProvider类的getBinding方法获取绑定提供程序，并将SOAP处理程序添加到处理程序链中。

YourService service = new YourService();
YourPort port = service.getYourPort();

BindingProvider bindingProvider = (BindingProvider) port;
List<Handler> handlerChain = bindingProvider.getBinding().getHandlerChain();
handlerChain.add(new HeaderHandler());
bindingProvider.getBinding().setHandlerChain(handlerChain);

// 现在可以使用您的端口发送请求，请求将包含所设置的请求头

通过这种方式，您可以在WSDL中设置请求头。请确保根据实际情况修改命名空间URI、前缀和请求头元素的名称
