【问题描述】：

我到处搜索，但找不到这个问题的答案。
我正在使用 spring-ws 创建一个可以使用 SOAP 消息的 url。我遵循了Producing a SOAP web service spring 教程。

当我向这个对象发送一个值时，所有属性都为空。我想要消息属性的值。我似乎无法弄清楚为什么所有属性都为空。
端点如下所示：

@PayloadRoot(namespace = NAMESPACE_URI, localPart = "UICMessage")
@ResponsePayload
public void getMessage(@RequestPayload JAXBElement<UICMessage> request) {
    System.out.println(request.getValue());

    JAXBContext jaxbContext;
    try {
        jaxbContext = JAXBContext.newInstance(UICMessage.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        jaxbMarshaller.setProperty("com.sun.xml.bind.characterEscapeHandler", (CharacterEscapeHandler) (ch, start, length, isAttVal, out) -> out.write(ch, start, length));
        StringWriter sw = new StringWriter();
        jaxbMarshaller.marshal(request, sw);
        String xmlString = sw.toString();

        System.out.println(xmlString);

        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        UICMessage uicMessage = (UICMessage) unmarshaller.unmarshal(new StringSource(xmlString));            

        System.out.println(uicMessage.getMessage());
    } catch (JAXBException e) {
        e.printStackTrace();
    }
}

我在 POST 请求中发送到上述端点 /ws/ci 的 SOAP 消息

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:head="http://uic.cc.org/UICMessage/Header" xmlns:uic="http://uic.cc.org/UICMessage">    
   <soapenv:Header>    
      <head:signed>false</head:signed>   
      <head:encrypted>false</head:encrypted>    
      <head:compressed>false</head:compressed>    
      <head:messageIdentifier>xxx</head:messageIdentifier>    
   </soapenv:Header>    
   <soapenv:Body>    
      <uic:UICMessage>      
         <message>    
             <TrainCompositionMessage xmlns="http://taf-jsg.info/schemes" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">XMLVALUE</TrainCompositionMessage>    
          </message>   
          <senderAlias>USER</senderAlias>  
      </uic:UICMessage>    
   </soapenv:Body>    
</soapenv:Envelope>

我从端点获取的控制台日志。
首先，我试图立即记录属性。所有属性均为空。接下来我尝试再次将它们编组为一个字符串，这些属性是可见的并且很好。
接下来我尝试再次解组它们，所有属性再次为空。

UICMessage{message=[message: null], signature=null, senderAlias=[senderAlias: null], encoding=null}

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:UICMessage xmlns:ns2="http://uic.cc.org/UICMessage">
    <message xmlns:head="http://uic.cc.org/UICMessage/Header" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:uic="http://uic.cc.org/UICMessage">
        <TrainCompositionMessage xmlns="http://taf-jsg.info/schemes" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">XMLVALUE</TrainCompositionMessage>    
    </message>
    <senderAlias xmlns:head="http://uic.cc.org/UICMessage/Header" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:uic="http://uic.cc.org/UICMessage">USER</senderAlias>
</ns2:UICMessage>

[message: null]

谁能帮我解决这个问题？这对我来说真的很奇怪。

【解决方案1】：

目前我们以一种非常肮脏的方式解决了这个问题。我们首先将消息转换为 XML，然后使用子字符串获取正确的部分。接下来，我们使用 jaxb 将我们需要的部分转换回一个对象。如果有人知道这样做的干净方法，请告诉我。

jaxbContext = JAXBContext.newInstance(UICMessage.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
jaxbMarshaller.setProperty("com.sun.xml.bind.characterEscapeHandler", (CharacterEscapeHandler) (ch, start, length, isAttVal, out) -> out.write(ch, start, length));
StringWriter sw = new StringWriter();
jaxbMarshaller.marshal(request, sw);
String xmlString = sw.toString();
String hackedString = xmlString.substring(xmlString.indexOf("<TrainCompositionMessage"), xmlString.indexOf("</message"));
jaxbContext = JAXBContext.newInstance(TrainCompositionMessage.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
TrainCompositionMessage errorMessage = (TrainCompositionMessage) unmarshaller.unmarshal(new StringSource(hackedString));
