java - 如何获取 MOXy oxml 映射文件以识别静态类

Question

使用 MOXy，我可以在 json 输出中展平部分对象模型

即

<java-type name="Medium">
  <java-attributes>
    <xml-element java-attribute="trackList" xml-path="."/>
  </java-attributes>
</java-type>

但是当我想折叠一个静态类的子类时，如下所示

<java-type name="Medium.TrackList">
  <java-attributes>
    <xml-element java-attribute="artistList" xml-path="."/>
  </java-attributes>
</java-type>

它提示

Exception Description: Could not load class [Medium.TrackList] declared in the external metadata file.  Please ensure that the class name is correct, and that the correct ClassLoader has been set.

    at org.eclipse.persistence.jaxb.JAXBContext$TypeMappingInfoInput.createContextState(JAXBContext.java:879)
    at org.eclipse.persistence.jaxb.JAXBContext.<init>(JAXBContext.java:157)

我该如何解决？

在 OXM 中指定内部类时，EclipseLink 实际上需要“$”分隔符。我重现了您的问题，并通过在您的 oxm 文件中更改此问题来修复它。

<java-type name="Medium$TrackList">
  <java-attributes>
    <xml-element java-attribute="artistList" xml-path="."/>
  </java-attributes>
</java-type>
