问题描述
有异常
javax.xml.bind.UnmarshalException: unexpected element
(uri:"", local:"ConnectorCommandType")
尝试unmarshall xml，如下所示：
trying to unmarshall xml, shown below:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ConnectorCommandType> ........ </ConnectorCommandType>
该异常基本上表示在jaxb上下文中找不到该元素。但调试显示此类在当前jaxb上下文中存在且已知。 ConnectorCommandType类是从xsd xml生成的< xs：complexType> 元素。
The exception basically says that element is not found in jaxb context. But debugging shows that this class is present and known in current jaxb context. The class ConnectorCommandType was generated from xsd xml as <xs:complexType> element.
xsd会出错吗？
有没有人遇到这样的问题？有什么建议？谢谢。
Has anyone faced with problem like that? Any suggestions? Thanks.
推荐答案
解决方案取决于以下问题的答案：
The solution depends on the answer to the following question:
ConnectorCommandType 类上是否有 @XmlRootElement（name =ConnectorCommandType）注释，或者 ObjectFactory 类中的create方法上的 @XmlElementDecl（name =ConnectorCommandType）？
Is there an @XmlRootElement(name="ConnectorCommandType") annotation on the ConnectorCommandType class, or an @XmlElementDecl(name="ConnectorCommandType") on a create method in the ObjectFactory class?
如果答案是肯定
是否有 package-info 吗？看起来好像是你的

如果答案为否
如果 ConnectorCommandType 元素不是与类关联，那么你将需要
使用一个带有类参数的unmarshal方法。
If the ConnectorCommandType element is not associated with a class, then you will need touse one of the unmarshal methods that takes a class parameter.
