从 Java 客户端调用 SOAP 服务时出现错误请求 [400] - 如何设置有效负载？

Question

我正在使用带有 Java 11 的 SpringBoot。

我正在尝试使用 SOAP web 服务，但出现以下错误：

org.springframework.ws.client.WebServiceTransportException：错误请求 [400]

I can however call the web service successfully (200) in Postman and SOAP UI, so there's something wrong with my Java code ( ProconSoapClient.java ).

Postman 请求（200）：

curl --location --request POST 'http://******/ProCONWS/WebService_PCSOrderEntry.asmx' \
--header 'Content-Type: application/soap+xml;charset=UTF-8;action="http://www.procon.dk/calculate_MD5"' \
--header 'Content-Length: 458' \
--data-raw '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:proc="http://www.procon.dk/">
   <soap:Header/>
   <soap:Body>
      <proc:calculate_MD5>
         <proc:user>*****</proc:user>
         <proc:timestamp>20220915 144942</proc:timestamp>
         <proc:Secret_word>********</proc:Secret_word>
      </proc:calculate_MD5>
   </soap:Body>
</soap:Envelope>'

Java 代码（400）：

ProconSoapClient.java

如何设置正文（有效负载）？ objectFactory.createString接受String但我需要发送CalculateMD5 。

// request headers
Map<String, String> headers = new HashMap<>();
headers.put("Cache-Control", "no-cache");
headers.put("Accept-Encoding", "gzip,deflate");
headers.put("Content-Type", "application/soap+xml;charset=UTF-8;action=\"http://www.procon.dk/calculate_MD5\"");
headers.put("Content-Length", "458");
headers.put("Connection", "Keep-Alive");
//headers.put("charset", "utf-8");
WebServiceMessageCallback callback = getRequestCallback(headers);

// request object
ObjectFactory objectFactory = new ObjectFactory();
CalculateMD5 calculateMD5 = objectFactory.createCalculateMD5();
calculateMD5.setUser(PROCON_SOAP_ACCESS_USER);
calculateMD5.setTimestamp(URLEncoder.encode(DateUtil.dateToString(new Date(), "yyyyMMdd HHmmss"), StandardCharsets.UTF_8));
calculateMD5.setSecretWord(PROCON_SOAP_ACCESS_SECRETWORD);

// payload
final String payload = marshal(calculateMD5);
// todo: what must go here? accepts a String but the object is a CalculateMD5
JAXBElement<String> jaxbElementPayload = objectFactory.createString(payload);

// call the SOAP service
Object response = getWebServiceTemplate().marshalSendAndReceive(PROCON_SOAP_ACCESS_URL, jaxbElementPayload, callback);

生成的类：

CalculateMD5和ObjectFactory对象是从 WSDL 生成的。
