spring JAXBException：“包”不包含 ObjectFactory.class 或 jaxb.in​​dex

JAXBException: "package" doesnt contain ObjectFactory.class or jaxb.index

提问by avi.elkharrat

I have been playing with JAXB / MOXy a lot lately, and it works great on all my tests and example codes. I exclusively using binding files, that's why I'm using MOXy.

我最近一直在玩 JAXB/MOXy，它在我所有的测试和示例代码中都运行良好。我只使用绑定文件，这就是我使用 MOXy 的原因。

Please note that in all my examples, I'm NEVER using an ObjectFactory nor a jaxb.index, and it works GREAT.

请注意，在我的所有示例中，我从不使用 ObjectFactory 或 jaxb.in​​dex，并且它运行良好。

When I get back to my business, I get a nasty JAXB Exception saying that my package does not contain an ObjectFactory or jaxb.index.

当我回到我的工作中时，我收到一个令人讨厌的 JAXB 异常，说我的包不包含 ObjectFactory 或 jaxb.in​​dex。

My project also invovles Spring and Hibernate, JUnit and DBUnit.

我的项目还涉及 Spring 和 Hibernate、JUnit 和 DBUnit。

Here is some sample code: I have an abstract class called AContributionPhysicalSupport.

Here is my binding file (there are other classes inheriting from AContributionPhysicalSupport....)

这是我的绑定文件（还有其他类继承自 AContributionPhysicalSupport....）

And now my test :

现在我的测试：

@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);
}

and last but not least the Exception :

最后但并非最不重要的 Exception ：

More info :

更多信息 ：

• My test package (where I have my JUnit test class) contains a jaxb.properties file
• My JUnit test class is really a DBUnit / SpringJUnit class, since I want to marshal objects from a DB
• Marshalling from DB or marshalling a simple object (like shown in my example) generate the same Exception
• And, of course, adding a jaxb.index in the package doesn't change anything

• 我的测试包（我有我的 JUnit 测试类）包含一个 jaxb.properties 文件
• 我的 JUnit 测试类实际上是一个 DBUnit / SpringJUnit 类，因为我想从 DB 中编组对象
• 从 DB 编组或编组一个简单的对象（如我的示例中所示）生成相同的异常
• 而且，当然，在包中添加 jaxb.in​​dex 不会改变任何东西

Four eyes are better than two. I'm not getting what I'm doing wrong. If somebody sees it, please let me know.

四眼总比两眼好。我不明白我做错了什么。如果有人看到，请告诉我。

Provider com.sun.xml.internal.bind.v2.ContextFactory could not be instantiated- seems like you're not using MOXy but the built-in JAXB RI.

Provider com.sun.xml.internal.bind.v2.ContextFactory could not be instantiated- 似乎您没有使用 MOXy，而是使用内置的 JAXB RI。

Please check the following post by Blaise:
