問題描述

我正在嘗試使用moxy繼承的堆棧跟蹤，有人可以提供一些建議。 波紋管的一些抽象的Java代碼和堆棧錯誤。 提前致謝！！！

1 個解決方案

注意：我是EclipseLink JAXB（MOXy）的負責人，並且是JAXB（JSR-222）專家組的成員。

我將幫助您解決此問題。

JSON提供者

第一個問題是，好像沒有拾取MOXyJsonProvider ，並且CXF默認為基於默認JAXB的JSON綁定。 這導致拋出JAXB Ri異常。

原因：javax.ws.rs.WebApplicationException：com.sun.xml.bind.v2.runtime.IllegalAnnotationsException：1個IllegalAnnotationExceptions計數無效@XmlElementRef：類型“類packagename.payment.ContactInfo”或其任何子類是未知的在這種情況下。 此問題與以下位置有關：位於packagename.payment.Customer的公共packagename.payment.ContactInfo packagename.payment.Customer.getContactInfo（） 

 at org.apache.cxf.jaxrs.provider.AbstractJAXBProvider.handleExceptionEnd(AbstractJAXBProvider.java:585) at org.apache.cxf.jaxrs.provider.AbstractJAXBProvider.handleJAXBException(AbstractJAXBProvider.java:597) at org.apache.cxf.jaxrs.provider.json.JSONProvider.writeTo(JSONProvider.java:361) at org.apache.cxf.jaxrs.client.AbstractClient.writeBody(AbstractClient.java:401) ... 30 more

子類

您需要讓MOXy知道子類。 一種方法是通過@XmlSeeAlso批注。 

@XmlSeeAlso({PhoneNumber.class, Address.class})
public abstract class ContactInfo {

}

UPDATE

我在EclipseLink 2.4.2和2.5.0流中簽入了對MOXyJsonProvider的修復程序，以修復在RESTEasy中運行時的問題。 這可能與您在CXF中看到的問題有關，也可能無關。 該修復程序將在2013年2月22日開始的夜間版本中從以下位置提供：
