如何在Jaxb编写的XML中添加<![CDATA [和]]>

Question

如何使用CDATA准备XML,

我通过Jaxb预先做出这个回应,

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
 <SOAP-ENV:Header/>
 <soapenv:Body>
   <tem:RequestData>
     <tem:requestDocument>
        <![CDATA[
        <Request>
           <Authentication CMId="68" Function="1" Guid="5594FB83-F4D4-431F-B3C5-EA6D7A8BA795" Password="poihg321TR"/>
           <Establishment Id="4297867"/>
        </Request>
        ]]>
      </tem:requestDocument>
   </tem:RequestData>
 </soapenv:Body>
 </soapenv:Envelope>  

但是从Jaxb我没有得到CDATA,如何把CDATA放在<tem:requestDocument>元素中.

这是我的Java代码:

  public static String test1() {
    try {
        initJB();
        String response = null;
        StringBuffer xmlStr = null;
        String strTimeStamp = null;
        com.cultagent4.travel_republic.gm.Envelope envelope = null;
        com.cultagent4.travel_republic.gm.Header header = null;
        com.cultagent4.travel_republic.gm.Body body = null;
        com.cultagent4.travel_republic.gm.RequestData requestData = null;
        com.cultagent4.travel_republic.gm.RequestDocument requestDocument = null;
        com.cultagent4.travel_republic.gm.RequestDocument.Request request = null;
        com.cultagent4.travel_republic.gm.RequestDocument.Request.Authentication authentication = null;
        com.cultagent4.travel_republic.gm.RequestDocument.Request.Establishment establishment = null;

        ObjectFactory objFact = new ObjectFactory();
        envelope = objFact.createEnvelope();
        header = objFact.createHeader();
        envelope.setHeader(header);
        body = objFact.createBody();
        requestData = objFact.createRequestData();


        requestDocument = objFact.createRequestDocument();
        request = new RequestDocument.Request();

        authentication = new RequestDocument.Request.Authentication();
        authentication.setCMId("68");
        authentication.setGuid("5594FB83-F4D4-431F-B3C5-EA6D7A8BA795");
        authentication.setPassword("poihg321TR");
        authentication.setFunction("1");
        request.setAuthentication(authentication);
        establishment = new RequestDocument.Request.Establishment();
        establishment.setId("4297867");
        request.setEstablishment(establishment);
        requestDocument.setRequest(request);
        requestData.setRequestDocument(requestDocument);
        body.setRequestData(requestData);
        envelope.setBody(body);



        jaxbMarshallerForBase = jaxbContextForBase.createMarshaller();
        OutputStream os = new ByteArrayOutputStream();


        System.out.println();
        // output pretty printed

//                jaxbMarshallerForBase.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
//                jaxbMarshallerForBase.marshal(envelope, System.out);
//                jaxbMarshallerForBase.marshal(envelope, os);


        jaxbMarshallerForBase.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
        jaxbMarshallerForBase.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
//            jaxbMarshallerForBase.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, false);
// get an Apache XMLSerializer configured to generate CDATA
        XMLSerializer serializer = getXMLSerializer();


// marshal using the Apache XMLSerializer
        SAXResult result = new SAXResult(serializer.asContentHandler());

         System.out.println("*************");
        jaxbMarshallerForBase.marshal(envelope, result);
        System.out.println("--------------");



        return null;
    } catch (JAXBException ex) {
        Logger.getLogger(GM_TravelRepublic.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        return null;
    }
}

private static XMLSerializer getXMLSerializer() {
    // configure an OutputFormat to handle CDATA
    OutputFormat of = new OutputFormat();

    // specify which of your elements you want to be handled as CDATA.
    // The use of the ; '^' between the namespaceURI and the localname
    // seems to be an implementation detail of the xerces code.
    // When processing xml that doesn't use namespaces, simply omit the
    // namespace prefix as shown in the third CDataElement below.
    of.setCDataElements(new String[]{"^Request","^Authentication","^Establishment"});


    // set any other options you'd like
   of.setPreserveSpace(true);
    of.setIndenting(true);


    StringWriter writer = new StringWriter();
    // create the serializer
    XMLSerializer serializer = new XMLSerializer(of);


    serializer.setOutputByteStream(System.out);


    return serializer;
}  

在这里我得到相同的xml,但没有CDATA.没有CDATA,我的服务器不接受请求.请帮忙.

Answer 1

你能从中得出逻辑吗

进口

import org.dom4j.CDATA;
import org.dom4j.DocumentHelper;

示例代码

public static String appendCdata(String input) {
    CDATA cdata = DocumentHelper.createCDATA(input);      
    return cdata.asXML();
}

1. 您需要创建一个扩展XMLAdapter类的自定义适配器类。

导入javax.xml.bind.annotation.adapters.XmlAdapter;

公共类CDATAAdapter扩展XmlAdapter {

@Override
public String marshal(String inStr) throws Exception {
    return "<![CDATA[" + inStr + "]]>";
}

@Override
public String unmarshal(String v) throws Exception {
    return inStr;
}

}

2. 在您的Java Bean或POJO中，在CDATA中所需的字符串上定义XMLJavaTypeAdapter

   @XmlJavaTypeAdapter（value = CDATAAdapter.class）私有字符串消息；

3. 默认情况下，JAXB RI的编组实现尝试转义字符。要更改此行为，我们编写一个实现CharacterEscapeHandler的类。

该接口具有一个需要重写的转义方法。

导入com.sun.xml.internal.bind.marshaller.CharacterEscapeHandler;

m.setProperty("com.sun.xml.internal.bind.characterEscapeHandler",
                new CharacterEscapeHandler() {
                    @Override
                    public void escape(char[] ch, int start, int length,
                            boolean isAttVal, Writer writer)
                            throws IOException {
                        writer.write(ch, start, length);
                    }
                });

其次，它也可以通过Eclipse MOXy实现来完成。

我认为在你的private static XMLSerializer getXMLSerializer()方法中你设置了错误的CDATA元素，因为你的CDATA元素是<tem:requestDocument>而不是Request Authentication内容Establishment。尝试使用：

of.setCDataElements(new String[]{"tem^requestDocument","http://tempuri.org/^requestDocument","requestDocument"});

代替：

of.setCDataElements(new String[]{"^Request","^Authentication","^Establishment"});

希望这可以帮助，
