Xml transient not working jaxb(Moxy).?

问题

Xml transient annotation not working for following model-

@XmlRootElement
public class JdfValidation {
private String name;
private String dataType;
private String errorMessage;
private String javaValidationLogic;
protected String displayName;
private boolean isCustom;
private List<ValidationInputParam> validationInputParams = new ArrayList<ValidationInputParam>();
public IFile container;

public JdfValidation() {

}

public JdfValidation(String name, String displayName, boolean isCustom) {
    this.name = name;
    this.displayName = displayName;
    this.isCustom = isCustom;
}

@XmlTransient
public IFile getContainer() {
    return container;
}

public void setContainer(IFile container) {
    this.container = container;
}

/**
 * @return the validationInputParams
 */
@XmlElement
public List<ValidationInputParam> getValidationInputParams() {
    return validationInputParams;
}

/**
 * @param validationInputParams
 *            the validationInputParams to set
 */
public void setValidationInputParams(
        List<ValidationInputParam> validationInputParams) {
    this.validationInputParams = validationInputParams;
}

@XmlAttribute
public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@XmlAttribute
public String getDataType() {
    return dataType;
}

public void setDataType(String dataType) {
    this.dataType = dataType;
}

@XmlAttribute
public String getErrorMessage() {
    return errorMessage;
}

public void setErrorMessage(String errorMessage) {
    this.errorMessage = errorMessage;
}

@XmlElement(name = "logic")
public String getJavaValidationLogic() {
    return javaValidationLogic;
}

public void setJavaValidationLogic(String javaValidationLogic) {
    this.javaValidationLogic = javaValidationLogic;
}

@XmlAttribute
public String getDisplayName() {
    return displayName;
}

public void setDisplayName(String displayName) {
    this.displayName = displayName;
}

@XmlAttribute
public boolean isCustom() {
    return isCustom;
}

public void setCustom(boolean isCustom) {
    this.isCustom = isCustom;
}

}

I also tried @XmlAccessorType(XmlAccessType.NONE) bu still same exception,above works with default jaxb implementation.Plz,help.

Caused by: Exception [EclipseLink-50089] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.JAXBException Exception Description: The java interface org.eclipse.core.resources.IFile can not be mapped by JAXB as it has multiple mappable parent interfaces. Multiple inheritence is not supported

UPDATE

We have fixed the bug behind this issue (see: http://bugs.eclipse.org/411993) it will be available in the EclipseLink 2.5.1 and 2.6.0 streams starting on July 4, 2013. You can download a nightly build from the following link:

http://www.eclipse.org/eclipselink/downloads/nightly.php

ISSUE

There appears to be a bug when MOXy is told (with @XmlTransient) to ignore a property if the type is an interface with multiple super interfaces.

1 Super Interface - Works

public interface IFile extends IFoo  {

}

More Than 1 Super Interface - Doesn't Work

public interface IFile extends IFoo, IBar {

}

You can use the following bug to track our progress on this issue.

WORKAROUND

You can use MOXy's external mapping document to override the supertype of IFile to make your use case work (see: http://blog.bdoughan.com/2010/12/extending-jaxb-representing-annotations.html):

oxm.xml

<?xml version="1.0"?>
<xml-bindings
    xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm"
    package-name="forum17399333">
    <java-types>
        <java-type name="IFile" super-type="java.lang.Object"/>
    </java-types>
</xml-bindings>

Demo

import java.util.*;
import javax.xml.bind.JAXBContext;
import org.eclipse.persistence.jaxb.JAXBContextProperties;

public class Demo {

    public static void main(String[] args) throws Exception {
        Map<String, Object> properties = new HashMap<String, Object>(1);
        properties.put(JAXBContextProperties.OXM_METADATA_SOURCE, "forum17399333/oxm.xml");
        JAXBContext jc = JAXBContext.newInstance(new Class[] {JdfValidation.class}, properties);
    }

}

Another work around could be -

@XmlRootElement(name = "Validator")
public class JdfValidation {


private Object container; //Cast this to appropriate type

@Transient
public Object getContainer() {
    return container;
}

public void setContainer(Object container) {
    this.container = container;
}
}

Demo-

public class Demo {

public static void main(String[] args) throws Exception {
    JAXBContext jc = JAXBContext.newInstance(JdfValidation.class);

    JdfValidation jdfValidation  = new JdfValidation();
            IFile file=getFile();
            jdfValidation.setContainer(file);
            Marshaller marshaller = jc.createMarshaller();
    marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
    marshaller.marshal(jdfValidation, System.out);
}

    }
