spring boot SOAP 生产者 - 输入对象列表始终为空

Question

我在尝试使用对象列表作为输入在 Springboot 中生成 SOAP Web 服务时遇到问题。

当我调用服务时，标量值正在解组，但列表仅包含空数组。

我不知道我错过了什么.... 我无法更改 WSDL 定义。

有点难理解，所以我在Github上重现了这个问题。

这是我的端点定义。一旦代码到达 doc.getDocFormat().getValue() 部分，试图从列表中读取，它就会抛出 Cannot invoke "javax.xml.bind.JAXBElement.getValue(), basically a NullPointerException.

@Endpoint
public class MergeTiffEndpoint {
    private static final String NAMESPACE_URI = "urn:Gekon";

    Logger logger = LoggerFactory.getLogger(MergeTiffEndpoint.class);

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "MERGE_TIFFRequestElement")
    @ResponsePayload
    public MERGETIFFReturn merge(@RequestPayload MERGETIFFQuery request) {

        List<InputSetRow> list = request.getDocuments().getValue().getDocument();

        logger.info("List size is " + list.size());

        list.forEach((doc) ->
                System.out.println("Value is " + doc.getDocFormat().getValue())
        );

        return null;
    }
}

这是来自客户的电话：

                <ns1:document xsi:type="ns1:InputSetRow">

                    <options xsi:nil="true"/>

            </ns1:documents>

        </ns1:MERGE_TIFFRequestElement>
    </soapenv:Body>
</soapenv:Envelope>

我使用jaxb2-maven-plugin并从 wsdl 文件生成了 pojo 存根。

生成了以下相关类：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "MERGE_TIFFQuery", propOrder = {
    "documents",
    "storageType",
    "applId"
})
public class MERGETIFFQuery {

    @XmlElementRef(name = "documents", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<InputSet> documents;
    @XmlElementRef(name = "storage_type", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<String> storageType;
    @XmlElementRef(name = "appl_id", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<String> applId;

-- standard getters and setters

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

    @XmlElement(nillable = true, namespace = "urn:Gekon")
    protected List<InputSetRow> document;

    public List<InputSetRow> getDocument() {
        if (document == null) {
            document = new ArrayList<InputSetRow>();
        }
        return this.document;
    }
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "InputSetRow", propOrder = {
    "docFormat",
    "location",
    "options",
    "content"
})
@XmlRootElement
public class InputSetRow {

    @XmlElementRef(name = "doc_format", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<String> docFormat;
    @XmlElementRef(name = "location", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<String> location;
    @XmlElementRef(name = "options", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<String> options;
    @XmlElementRef(name = "content", namespace = "urn:Gekon", type = JAXBElement.class, required = false)
    protected JAXBElement<Base64Binary> content;

-- standard getters and setters

我真的不知道我错过了什么。
任何帮助表示赞赏。

Answer 1

好的，明白了。

客户端发出的调用没有命名空间引用。

<ns1:document xsi:type="ns1:InputSetRow">
   <ns1:doc_format xsi:type="xsd:string">TIFF</doc_format>
   <location xsi:type="xsd:string">c:\Users\zizam\private\gekonTests\file-convertor\files\input\merge_tiff_single.tif</location>
   <options xsi:nil="true"/>
</ns1:document>

当我以 ns1:doc_format 格式拨打电话时，一切正常。所以让它工作的唯一方法是将 InutSetRow 中的命名空间引用更改为 InputSetRow 到 namespace = ""
