项目方案：创建一个Java程序实现SoapHeader

1. 项目背景

在使用SOAP（Simple Object Access Protocol）通信协议时，有时需要在SOAP消息的头部添加一些自定义的信息，这就需要在Java程序中创建一个SoapHeader。本项目旨在演示如何使用Java创建一个SoapHeader，并将其添加到SOAP消息中。

2. 技术选型

Java
SOAP

3. 项目实现步骤

步骤一：创建一个SoapHeaderHandler类

import javax.xml.namespace.QName;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
import java.util.Set;

public class SoapHeaderHandler implements SOAPHandler<SOAPMessageContext> {

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        try {
            SOAPMessage soapMessage = context.getMessage();
            SOAPHeader soapHeader = soapMessage.getSOAPHeader();

            // 在此处添加自定义的SoapHeader信息
            QName qname = new QName(" "CustomHeader");
            soapHeader.addHeaderElement(qname);

            return true;
        } catch (SOAPException e) {
            e.printStackTrace();
            return false;
        }
    }

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

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

    @Override
    public void close(MessageContext context) {
    }
}

步骤二：在服务端添加SoapHandler

import javax.xml.ws.Endpoint;
import javax.xml.ws.Binding;
import javax.xml.ws.handler.Handler;
import java.util.List;

public class Server {

    public static void main(String[] args) {
        String address = "http://localhost:8080/Service";
        Endpoint endpoint = Endpoint.publish(address, new ServiceImpl());

        Binding binding = endpoint.getBinding();
        List<Handler> handlerChain = binding.getHandlerChain();
        handlerChain.add(new SoapHeaderHandler());
        binding.setHandlerChain(handlerChain);
    }
}

4. 类图设计

classDiagram
    class SoapHeaderHandler {
        handleMessage(SOAPMessageContext context)
        getHeaders()
        handleFault(SOAPMessageContext context)
        close(MessageContext context)
    }
    class Server {
        main(String[] args)
    }
