Exception in thread “main” javax.xml.bind.JAXBException: Provider com.sun.xml.bind.v2.ContextFactory

今天配置xml文件解析的时候出现如下错误

<pre name="code" class="html">javax.xml.bind.JAXBException: Provider com.sun.xml.internal.bind.v2.ContextFactory could not be instantiated: javax.xml.bind.JAXBException: "com.axd.zicon.model" doesnt contain ObjectFactory.class or jaxb.index
- with linked exception:

我的代码如下：

Class clazz = ConfigurationDefinition.class;

final JAXBContext context = JAXBContext.newInstance(clazz
.getPackage().getName(), clazz.getClassLoader());
final Unmarshaller unmarshaller = context.createUnmarshaller();

网上找的一些方法都没有解决，后来在com.axd.zicon.model包下新增了一个jaxb.index文件，错误解决。index文件包含的内容为Javabean的类名。

jaxb.index包含内容：

ConfigurationDefinition
FilterDefinition
