Spring Boot -如何向SOAP响应添加自定义头？

import org.springframework.ws.soap.SoapEnvelope;
import org.springframework.ws.soap.SoapHeader;
import org.springframework.ws.soap.SoapMessage;
import org.springframework.ws.soap.saaj.SaajSoapMessage;
import org.springframework.ws.soap.server.endpoint.interceptor.SoapEnvelopeInterceptor;

public class CustomSoapInterceptor implements SoapEnvelopeInterceptor {

    @Override
    public boolean handleRequest(SoapMessage message, Object endpoint) {
        return true;
    }

    @Override
    public boolean handleResponse(SoapMessage message, Object endpoint) {
        SoapEnvelope envelope = ((SaajSoapMessage) message).getSaajMessage().getSOAPPart().getEnvelope();
        SoapHeader header = envelope.getHeader();
        
        // 创建自定义头部元素
        QName customHeaderQName = new QName("http://example.com/namespace", "CustomHeader");
        SoapHeaderElement customHeaderElement = header.addHeaderElement(customHeaderQName);
        customHeaderElement.setText("Custom Header Value");
        
        return true;
    }

    @Override
    public boolean handleFault(SoapMessage message, Object endpoint) {
        return true;
    }

    @Override
    public void afterCompletion(SoapMessage message, Object endpoint, Exception ex) {
    }
}
