如何在java代码中添加自定义soap标头和url？

import javax.xml.soap.*;

public class SOAPClient {
    public static void main(String[] args) {
        try {
            // 创建SOAP连接对象
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // 创建SOAP消息对象
            MessageFactory messageFactory = MessageFactory.newInstance();
            SOAPMessage soapMessage = messageFactory.createMessage();

            // 创建SOAP标头对象，并添加自定义标头信息
            SOAPHeader soapHeader = soapMessage.getSOAPHeader();
            QName headerName = new QName("http://example.com/namespace", "HeaderName", "prefix");
            SOAPHeaderElement headerElement = soapHeader.addHeaderElement(headerName);
            headerElement.addTextNode("Header value");

            // 创建SOAP主体对象，并添加请求数据
            SOAPBody soapBody = soapMessage.getSOAPBody();
            QName bodyName = new QName("http://example.com/namespace", "BodyName", "prefix");
            SOAPBodyElement bodyElement = soapBody.addBodyElement(bodyName);
            bodyElement.addTextNode("Request data");

            // 指定SOAP消息的目标URL
            URL endpointUrl = new URL("http://example.com/soap-endpoint");

            // 发送SOAP消息并接收响应
            SOAPMessage soapResponse = soapConnection.call(soapMessage, endpointUrl);

            // 处理SOAP响应数据
            // ...

            // 关闭SOAP连接
            soapConnection.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
