JAXBException：「包」不包含ObjectFactory.class或jaxb.in​​dex

Question

最近我一直在玩JAXB/MOXY，，它對我所有的測試和示例代碼都很有用。我專門使用綁定文件，這就是爲什麼我使用MOXY。

請注意，在我所有的例子中，我從來沒有使用ObjectFactory，也沒有使用jaxb.in​​dex，，它的工作原理是。

當我回到自己的業務時，出現一個討厭的JAXB異常，說我的包不包含ObjectFactory或jaxb.in​​dex。

我的項目還調用Spring和Hibernate，JUnit和DBUnit。

以下是一些示例代碼：我有一個名爲AContributionPhysicalSupport的抽象類。

現在我的測試：

@Test 
public void testYATMarshal() throws Exception 
{ 
    Video toto = new Video(); 
    toto.setPhysicalSupportId(new Long(1)); 
    toto.setSupportType("VIDEO"); 
    toto.setVideoLength(new Long(358)); 
    toto.setVideoSize(new Long(5775)); 
    toto.setVideoType("avi"); 

    FileReader videoBindFile = new FileReader(
      "src/main/resources/xml-mapping/ContributionImpl-binding.xml"); 
    List<Object> videoBindList = new ArrayList<Object>(); 
    videoBindList.add(videoBindFile); 

    Map<String, List<Object>> videoMetaMap = new HashMap<String, List<Object>>(); 
    videoMetaMap.put("org.pea.openVillages.pojo.contribution.implementation", videoBindList); 
    Map<String, Object> videoProperties = new HashMap<String, Object>(); 
    videoProperties.put(JAXBContextProperties.OXM_METADATA_SOURCE, videoMetaMap); 

    JAXBContext context = JAXBContext.newInstance("org.pea.openVillages.pojo.contribution.implementation", 
      Video.class.getClassLoader(), videoProperties); 
    Marshaller marshaller = context.createMarshaller(); 
    marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); 

    marshaller.marshal(toto, System.out); 
} 

和最後但並非最不重要的例外：

更多信息：

• 我的測試包（在那裏我有我的JUnit測試類）包含jaxb.properties文件
• 我的JUnit測試class實際上是一個DBUnit/SpringJUnit類，因爲我想編組來自DB的對象
• 從DB進行編組或者編組簡單對象（如我的示例中所示）會生成相同的異常
• 當然，在包中添加jaxb.in​​dex並不會改變任何東西

四隻眼睛比兩隻好。我不明白我做錯了什麼。如果有人看到它，請讓我知道。

乾杯

Answer 1

Provider com.sun.xml.internal.bind.v2.ContextFactory could not be instantiated - 好像你不使用莫西但內置的JAXB RI。

請布萊斯檢查下面的帖子：

Specifying EclipseLink MOXy as Your JAXB Provider

參見以下問題：

Does MOXy need anything special when using with schema-derived classes?

Answer 2

答案由Lex提供icore在他的評論中爲我做了！

我已經設置好的兩包，如圖Blaise's answer：

JAXBContext jc = JAXBContext.newInstance("com.example.pkg1:org.example.pkg2"); 

這做到了！
