InvalidMappingException：無法解析映射文檔

我多次嘗試運行簡單Hibernate項目，但錯誤出現得更多。我試圖使用Hibernate.cfg.xml文件，但沒有成功。使用Hibernate.cfg.xml只會出現NullPointerException。InvalidMappingException：無法解析映射文檔

您使用的是舊版本的JAXB的。版本2.2.11有null檢查：PropertyInfoImpl.java#371

case QUALIFIED: 
    QName typeName = parent.getTypeName(); 
    if(typeName!=null) { 
     uri = typeName.getNamespaceURI(); 
    } else { 
     uri = xs.namespace(); 
    } 
    if(uri.length()==0) { 
     uri = parent.builder.defaultNsUri; 
    } 
    break;

2.0版本不具有null檢查：PropertyInfoImpl.java#286

case QUALIFIED: 
    uri = parent.getTypeName().getNamespaceURI(); 
    if(uri.length()==0) { 
     uri = parent.builder.defaultNsUri; 
    } 
    break;
