WSDL客户端中的CDATA元素

Question

我正在做一个WSDL客户端,想知道如何将XML元素设置为CDATA.

我正在使用它wsimport来生成源代码,CDATA元素是请求XML的一部分.这是请求的XML类:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = { "dataRequest" }) 
@XmlRootElement(name = "ProcessTransaction")
public class ProcessTransaction {

    protected String dataRequest;

    public String getDataRequest() {
        return dataRequest;
    }

    public void setDataRequest(String value) {
        this.dataRequest = value;
    }  
} 

我已经尝试了@XmlAdapter,但它在输出上没有任何改变......

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

public class AdaptorCDATA extends XmlAdapter<String, String> {

    @Override
    public String marshal(String arg0) throws Exception {
        return "<![CDATA[" + arg0 + "]]>";
    }

    @Override
    public String unmarshal(String arg0) throws Exception {
        return arg0;
    }
}

在XML类中:

@XmlJavaTypeAdapter(value=AdaptorCDATA.class)
protected String dataRequest;

我试图调试,但它从不踩到这个AdaptorCDATA功能.

该wsimport版本2.2.9与jaxb-api版本2.1.

因此，正如@user1516873所建议的，我将代码移至 cxf，这样，运行良好。现在我使用“wsdl2java”来生成代码，并在我的项目中使用 cxf 生成 jar。

代码中有什么不同：

C数据拦截器

import javax.xml.stream.XMLStreamWriter;

import org.apache.cxf.message.Message;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;

public class CdataInterceptor extends AbstractPhaseInterceptor<Message> {

    public CdataInterceptor() {
        super(Phase.MARSHAL);
    }

    public void handleMessage(Message message) {
        message.put("disable.outputstream.optimization", Boolean.TRUE);
        XMLStreamWriter writer = (XMLStreamWriter) message.getContent(XMLStreamWriter.class);
        if (writer != null && !(writer instanceof CDataContentWriter)) {
            message.setContent(XMLStreamWriter.class, new CDataContentWriter(writer));
        }
    }

    public void handleFault(Message messageParam) {
        System.out.println(messageParam);
    }
}

CDataContentWriter

import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamWriter;

import org.apache.cxf.staxutils.DelegatingXMLStreamWriter;

public class CDataContentWriter extends DelegatingXMLStreamWriter {

    public CDataContentWriter(XMLStreamWriter writer) {
        super(writer);
    }

    public void writeCharacters(String text) throws XMLStreamException {
        boolean useCData = text.contains("RequestGeneric");
        if (useCData) {
            super.writeCData(text);
        } else {
            super.writeCharacters(text);
        }
    }

    // optional 
    public void writeStartElement(String prefix, String local, String uri) throws XMLStreamException {
        super.writeStartElement(prefix, local, uri);
    }
}

使用写入器和拦截器：

MyService wcf = new MyService(url, qName);
IMyService a = wcf.getBasicHttpBinding();

Client cxfClient = ClientProxy.getClient(a);
CdataInterceptor myInterceptor = new CdataInterceptor();
cxfClient.getInInterceptors().add(myInterceptor);
cxfClient.getOutInterceptors().add(myInterceptor);

而且效果很完美！
