IllegalAnnotationExceptions有與元素

Question

我同時用

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

運行在命令提示符項目得到了以下錯誤的@XmlElementDecl沒有的ObjectFactory我有以下錯誤

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：代碼在我的Eclipse上完全正常工作。但是當我嘗試在命令提示符上運行時，它會拋出異常

Answer 1

當從類創建JAXBContext時，需要在傳入的類中包含ObjectFactory類以創建JAXBContext。

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

如果從XML模式生成的模型，那麼我會建議創建包的名稱的JAXBContext：

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