XMLDirectMapping - 未提供转换值

标签： jaxb eclipselink moxy docx4j

docx4j（我主持）通常与Sun / Oracle JAXB实现一起使用;下面感兴趣的类是使用XJC生成的。

继MOXy guys kindly fixed之前的问题后，我继续尝试使用EclipseLink MOXy。

使用特定的DOM文档，我现在得到：

这与JAXBBinder.unmarshall有关。如果我使用JAXBUnmarshaller.unmarshal：

，会发生同样的事情 
[Exception [EclipseLink-25004] (Eclipse Persistence Services - 2.4.0.v20120529-r11529): org.eclipse.persistence.exceptions.XMLMarshalException

导致破坏的XML文件可以在https://gist.github.com/2834081和org.docx4j.math.CTOnOff is here找到。

有什么建议吗？

答案 0 :(得分：5)

注意：我EclipseLink JAXB (MOXy)领导JAXB (JSR-222)专家组成员。

正在解组的XML文档实际上是无效的。如果ns1:val属性中的值更改为与允许的枚举值匹配，那么一切都按预期工作。

XML文件

xml doc的第95行是

<m:radPr>
    <m:degHide m:val="1" />

<强> STOnOff

1不是有效值...应该是“开”或“关”

@XmlType(name = "ST_OnOff")
@XmlEnum
public enum STOnOff {

    @XmlEnumValue("on")
    ON("on"),
    @XmlEnumValue("off")
    OFF("off");
    private final String value;

}

<强> CTRadPr 

public class CTRadPr  implements Child
{
    protected CTOnOff degHide;
    protected CTCtrlPr ctrlPr;
    ...
}

<强> CTOnOff 

@XmlType(name = "CT_OnOff")
public class CTOnOff  implements Child
{
    @XmlAttribute(namespace = "http://schemas.openxmlformats.org/officeDocument/2006/math")
    protected STOnOff val;

MOXy中存在与处理无效值相关的错误。 MOXy应该做的是当它发现无效值时它应该向ValidationEventHandler报告错误。如果ValidationEventHandler处理事件，则不会为相应的字段/属性设置值。当您使用JAXB RI尝试此操作时，您将看到对象模型中未填充无效值

您可以使用以下错误来跟踪我们在此问题上的进展：

<强>更新

我们在EclipseLink 2.4.0流中修复了bug 381217。您可以从以下位置下载夜间标签：

注意：使用此修复程序，MOXy将报告无效属性值的验证事件，就像对无效元素值一样。这是来自JAXB-RI的行为，它抛出无效元素的验证事件但不是无效的属性。我相信RI行为是一个错误。
