这是一个包含名为 paramName 的抽象全局元素的 WSDL：

此元素旨在用在另一个名称空间中定义的相同命名元素替换 SOAP 消息。以下是此类定义的示例：

<schema targetNamespace="http://companyname.org/adapter1/" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:inptypns="http://companyname.org/" xmlns:tns="http://companyname.org/adapter1/">
   <import namespace="http://companyname.org/"/>
   <element name="paramName" substitutionGroup="inptypns:paramName" type="tns:AtomicParamNameType"/>
   <simpleType name="AtomicParamNameType">
      <restriction base="string">
         <enumeration value="foo"/>
         <enumeration value="bar"/>
      </restriction>
   </simpleType>
</schema>

这是实现此 Web 服务的 Java 代码，包括由 wsimport 生成的代码：

@WebService(wsdlLocation = "WEB-INF/wsdl/AdapterSessionManager.wsdl")
@BindingType(SOAPBinding.SOAP12HTTP_BINDING)
public class AdapterSessionManager {

    @WebMethod
    public Long initAdapterSession(
            @WebParam(name = "adapterId")
            @XmlElement(required = true)
            Long adapterId,

            @WebParam(name = "callbackURL")
            @XmlElement(required = true)
            URL callbackURL,

            @WebParam
            @XmlElement(required = true)
            AdapterInputDataType adapterInputData
    ) {...}
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "AdapterInputDataType", propOrder = {
    "atomicParam"
})
public class AdapterInputDataType {

    protected List<AtomicParamType> atomicParam;

    public List<AtomicParamType> getAtomicParam() {
        if (atomicParam == null) {
            atomicParam = new ArrayList<AtomicParamType>();
        }
        return this.atomicParam;
    }

}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "AtomicParamType", propOrder = {
    "paramName",
    "paramValue"
})
public class AtomicParamType {

    @XmlElementRef(name = "paramName", namespace = "http://companyname.org/", type = JAXBElement.class)
    protected JAXBElement<?> paramName;
    @XmlElement(required = true)
    protected String paramValue;

    public JAXBElement<?> getParamName() {
        return paramName;
    }

    public void setParamName(JAXBElement<?> value) {
        this.paramName = value;
    }

    public String getParamValue() {
        return paramValue;
    }

    public void setParamValue(String value) {
        this.paramValue = value;
    }
}

@XmlRegistry
public class ObjectFactory {

    private final static QName _ParamName_QNAME = new QName("http://companyname.org/", "paramName");

    public ObjectFactory() {
    }

    public AtomicParamType createAtomicParamType() {
        return new AtomicParamType();
    }

    public AdapterInputDataType createAdapterInputDataType() {
        return new AdapterInputDataType();
    }

    @XmlElementDecl(namespace = "http://companyname.org/", name = "paramName")
    public JAXBElement<String> createParamName(String value) {
        return new JAXBElement<String>(_ParamName_QNAME, String.class, null, value);
    }
}

@XmlType(name = "AtomicParamNameType", namespace = "http://companyname.org/adapter1/")
@XmlEnum
public enum AtomicParamNameType {

    @XmlEnumValue("foo")
    FOO("foo"),
    @XmlEnumValue("bar")
    BAR("bar");
    private final String value;

    AtomicParamNameType(String v) {
        value = v;
    }

    public String value() {
        return value;
    }

    public static AtomicParamNameType fromValue(String v) {
        for (AtomicParamNameType c: AtomicParamNameType.values()) {
            if (c.value.equals(v)) {
                return c;
            }
        }
        throw new IllegalArgumentException(v);
    }

}

@XmlRegistry
public class ObjectFactory {

    private final static QName _ParamName_QNAME = new QName("http://companyname.org/adapter1/", "paramName");

    public ObjectFactory() {
    }

    @XmlElementDecl(namespace = "http://companyname.org/adapter1/", name = "paramName", substitutionHeadNamespace = "http://companyname.org/", substitutionHeadName = "paramName")
    public JAXBElement<AtomicParamNameType> createParamName(AtomicParamNameType value) {
        return new JAXBElement<AtomicParamNameType>(_ParamName_QNAME, AtomicParamNameType.class, null, value);
    }

}

我正在使用以下 SOAP 请求测试服务：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://companyname.org/" xmlns:ans="http://companyname.org/adapter1/">
   <soapenv:Header/>
   <soapenv:Body>
      <ws:initAdapterSession>
         <adapterId>123</adapterId>
         <callbackURL>http://callback</callbackURL>
         <adapterInputData>
            <atomicParam>
               <ans:paramName>foo</ans:paramName>
               <paramValue>hello</paramValue>
            </atomicParam>
         </adapterInputData>
      </ws:initAdapterSession>
   </soapenv:Body>
</soapenv:Envelope>

当应用程序服务器收到请求时，我有以下 UnmarshallException：

javax.xml.bind.UnmarshalException：意外元素（uri：“ http://companyname.org/adapter1/ ”，本地：“paramName”）。预期的元素是 <{ http://companyname.org/ }paramName>,<{}paramValue>

看起来 JAXB 不知道命名空间中定义的 paramName 替换http://companyname.org/adapter1/。但我无法想象为什么 JAXB 会以这种方式行事。我的错误在哪里？有任何想法吗？

您已经知道答案：http://companyname.org/adapter1与http://companyname.org/不同。

您生成的源代码明确表明该paramName 元素是在http://companyname.org/命名空间中定义的，其中包含以下行。

@XmlElementRef(name = "paramName", namespace = "http://companyname.org/", type = JAXBElement.class)
protected JAXBElement<?> paramName;

因此，将namespace属性更改http://companyname.org/adapter1为允许 JAXB 正确解组您的有效负载
