JAXB 解组忽略 SOAP Envelope/Header 标记 [英] JAXB unmarshaling Ignoring the SOAP Envelope/Header tags

问题描述

我正在构建一个用于访问 Web 服务的客户端.我正在使用一些 JAXB 生成的类(Netbeans 6.9)来解组我的 xml 数据.

I have a client I am building for accessing a web service. I am using some JAXB generated classes(Netbeans 6.9) to unmarshal my xml data.

我在尝试解组来自此 Web 服务的 InputStream 响应时遇到意外的元素错误，如果我将响应保存到文件中，我也会遇到同样的意外元素错误.

I am getting unexpected element errors when trying to unmarshal the InputStream response from this webservice, I also get the same unexpected element error if I save the response to a file.

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.w3.org/2003/05/soap-envelope", local:"Envelope"). Expected elements are <{http://www.cmicdataservices.com/}Authentication>,....

将数据保存到文件后，我可以进入并删除 SOAP 标记(信封、正文、标题)，然后毫无问题地运行解组.

With the data saved to file I can go in and delete the SOAP tags(envelope,body,headr) and then run the unmarshaling with no problem.

我还没有真正找到让解组忽略这些标签的方法.有谁知道可以做些什么来忽略这些标签?

I have not really found a way to make the unmarshaling ignore these tags. Does anyone know what can be done to ignore those tags?

这里是主方法和流返回的类.

Here is the main method and the class returned by the stream.

   public static void main(String[] args) {
        JAXBContext jaxbContext = null;
        try {
            CMICData cmic = new CMICData();
            jaxbContext = JAXBContext.newInstance("cmic.ajrs.com");
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();


            GetCurrentDataVer1Response response = (GetCurrentDataVer1Response)
                    unmarshaller.unmarshal( cmic.getCMICIs("GetCurrentDataVer1"));
            DatacenterDataVer1 dataSet = response.getGetCurrentDataVer1Result();

            List products = dataSet.getAProductBase().getProductBase();
            // print some primary keys to show data being processed.
            for(Iterator<ProductBase> iter = products.iterator(); iter.hasNext();) {
                ProductBase pb = iter.next();
                System.out.println(pb.getPkID());
            }

        } catch (JAXBException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }
        catch (IOException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }


    }

Netbeans 生成的类.

The class generated by Netbeans.

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "getCurrentDataVer1Result"
})
@XmlRootElement(name = "GetCurrentDataVer1Response", namespace = "http://www.cmicdataservices.com/")
public class GetCurrentDataVer1Response {

    @XmlElement(name = "GetCurrentDataVer1Result")
    protected DatacenterDataVer1 getCurrentDataVer1Result;

    /**
     * Gets the value of the getCurrentDataVer1Result property.
     * 
     * @return
     *     possible object is
     *     {@link DatacenterDataVer1 }
     *     
     */
    public DatacenterDataVer1 getGetCurrentDataVer1Result() {
        return getCurrentDataVer1Result;
    }

    /**
     * Sets the value of the getCurrentDataVer1Result property.
     * 
     * @param value
     *     allowed object is
     *     {@link DatacenterDataVer1 }
     *     
     */
    public void setGetCurrentDataVer1Result(DatacenterDataVer1 value) {
        this.getCurrentDataVer1Result = value;
    }

}

推荐答案

有几个不同的选项:

选项#1

如果您以 InputStream 形式接收 XML 输入，则可以使用 StAX 对其进行解析并获得 XMLStreamReader.然后，您可以将 XMLStreamReader 推进到要解组的本地根元素并让 JAXB 解组它.

If you receive the XML input as an InputStream you could parse it with StAX and get an XMLStreamReader. You could then advance the XMLStreamReader to the local root element you want to unmarshal and have JAXB unmarshal it.

选项 #2

您可以使用 javax.xml.xpath 库以选择要使用 JAXB 解组的本地根元素.有关 javax.xml.xpath 示例，请参见:

You could use the javax.xml.xpath library to select the local root element that you want to unmarshal with JAXB. For a javax.xml.xpath example see:
