@XmlElementRef - 请求和响应的JAXBElement包装器(@XmlElementRef - JAXBElement wrappers for request and response)

 我用于我的Web服务请求和响应XML相同的@XmlElementRef元素，例如： 
 
 请求： 
 
@XmlElementRef(name = "elementId", namespace = "blah")
private JAXBElement<Long> elementId;
 
 响应： 
 
@XmlElementRef(name = "elementId", namespace = "blah")
private JAXBElement<Long> elementId;
 
 我想在响应的构造函数中实例化该元素。 我怎么能这样做，只需要new操作员？ 

I use for my web service request and response XML the same @XmlElementRef elements, for example:
 
request:
 
@XmlElementRef(name = "elementId", namespace = "blah")
private JAXBElement<Long> elementId;
 
response:
 
@XmlElementRef(name = "elementId", namespace = "blah")
private JAXBElement<Long> elementId;
 
I want to instantiate the element in the constructor of the response. How can I do that, just with new operator?
