java - IllegalAnnotationExceptions 元素没有带有 @XmlElementDecl 的 ObjectFactory

Question

在命令提示符下运行项目时出现以下错误

java com.javavids.jaxb.sitemap.main.Main

出现如下错误

Exception in thread "main"    com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
There's no ObjectFactory with an @XmlElementDecl for the element {unison}FromTime.
    this problem is related to the following location:

public static void main(String[] args) throws JAXBException {

    File file = new File("C:\\Users\\t_pavans\\workspace\\jaxbTest1\\medialossy.xml");

    JAXBContext jaxbContext = JAXBContext.newInstance(com.javavids.jaxb.sitemap.UPM.BMWebgateConf.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();

    //BMWebgate Root element variables
    bmw = (BMWebgateConf) jaxbUnmarshaller.unmarshal(file);

注意:该代码在我的 Eclipse 上完全可以正常工作。但是当我尝试在命令提示符下运行时，它会抛出异常

Answer 1

从类创建 JAXBContext 时，您需要在传入的类中包含 ObjectFactory 类以创建 JAXBContext。

JAXBContext jaxbContext = JAXBContext.newInstance(BMWebgateConf.class, ObjectFactory.class);

如果您的模型是从 XML 模式生成的，那么我建议在包名称上创建 JAXBContext:

JAXBContext jaxbContext = JAXBContext.newInstance("com.javavids.jaxb.sitemap");
