如何添加<！[CDATA [和]]>在Jaxb编写的XML中 [英] How to add <![CDATA[ and ]]> in XML prepared by Jaxb
问题描述
如何使用CDATA准备XML，
How to prepare XML with CDATA ,
我通过Jaxb预先发布此响应，
I am preraring this response via Jaxb,
<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。
But from Jaxb i am not getting CDATA , how to put CDATA inside <tem:requestDocument> element.
这是我的Java代码：
Here is my Java Code :
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;
}
这里我得到相同的xml，但没有CDATA。我的服务器在没有CDATA.Please帮助的情况下不接受请求。
Here I am getting same xml , but without CDATA. My server is not accepting the request without CDATA.Please help.
推荐答案
- 你需要创建一个自定义适配器类，它扩展了XMLAdapter类。
import javax.xml.bind.annotation.adapters.XmlAdapter;
import javax.xml.bind.annotation.adapters.XmlAdapter;
public class CDATAAdapter extends XmlAdapter {
public class CDATAAdapter extends XmlAdapter {
@Override
public String marshal(String inStr) throws Exception {
return "<![CDATA[" + inStr + "]]>";
}
@Override
public String unmarshal(String v) throws Exception {
return inStr;
}
}
-
在Java Bean或POJO中定义CDATA中所需字符串的XMLJavaTypeAdapter
Inside your Java Bean or POJO define XMLJavaTypeAdapter on the string required in CDATA
@XmlJavaTypeAdapter（value = CDATAAdapter） .class）
private String message;
@XmlJavaTypeAdapter(value=CDATAAdapter.class) private String message;
默认情况下，JAXB RI的marshaller实现尝试转义字符。为了改变这种行为，我们编写了一个
实现了CharacterEscapeHandler的类。
By default, the marshaller implementation of the JAXB RI tries to escape characters. To change this behaviour we write a class that implements the CharacterEscapeHandler.
这个接口有一个转义方法需要被覆盖的。
This interface has an escape method that needs to be overridden.
import com.sun.xml.internal.bind.marshaller.CharacterEscapeHandler;
import 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实现完成。
Secondly, it cn also be done via Eclipse MOXy implementation.
