Spring ws-Every属性返回null

Question

我到处找了，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。我学习了"生产SOAP web服务"春季教程

向该对象发送值时，所有属性都为null。我想要消息属性的值。我似乎不明白为什么所有的属性都为空
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请求中向位于/ws/ci 的上述端点发送的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，我尝试立即记录属性。所有属性都为null。接下来，我再次尝试将它们编组为一个字符串，属性是可见的并且很好
接下来，我再次尝试对它们进行解组，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]

有人能帮我吗？这对我来说真的很奇怪。

Answer 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得正确的部分。接下来，我们使用jaxb将需要的部分转换回一个对象。如果有人知道一个干净的方法，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));
