如何在jaxb中使用继承？

[英]How to use inheritance in jaxb?

 原文  2013-09-04 13:50:04  7   1    java/ xml/ jaxb

问题描述

I have an abstract class address, and two classes that inherit from class address.. 我有一个抽象的类地址，以及两个继承自类地址的类。

classA and classB. classA和classB。

So I found in google the annotation @xmlSeeAlso I used this, but I don´t know if it´s correct... 所以我在google中找到了注释@xmlSeeAlso我也用过这个，但我不知道它是否正确......

Because the stackTrace prints this error 因为stackTrace会输出此错误 

com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 11 counts of IllegalAnnotationExceptions

UPDATE UPDATE

put my code in pastebin.. To explain for you, my classes emitente and destinatario have a field with a endereco (adress) from from enderecoEmitente and enderecoDestinario and they extends from Endereco http://pastebin.com/db0M3rG5 把我的代码放在pastebin中。为了向您解释，我的类emitente和destinatario有一个带有来自enderecoEmitente和enderecoDestinario的endereco（地址）的字段，它们来自Endereco http://pastebin.com/db0M3rG5

Using your code on paste bin all I had to do was add @XmlAccessorType(XmlAccessType.FIELD) to the Endereco` to get everything to work correctly (since that class has annotated fields). 在粘贴bin上使用你的代码，我所要做的就是将@XmlAccessorType(XmlAccessType.FIELD) to the添加@XmlAccessorType(XmlAccessType.FIELD) to the Endereco`以使一切正常工作（因为该类具有注释字段）。 

@XmlAccessorType(XmlAccessType.FIELD)
public class Endereco {

Problem 问题

The problem you are encountering isn't related to inheritance but to the fact that you have annotated the field instead of the property. 您遇到的问题与继承无关，而是与您注释字段而不是属性有关。 By default a JAXB implementation will treat public properties and annotated fields as mapped (see: http://blog.bdoughan.com/2011/06/using-jaxbs-xmlaccessortype-to.html ), this is causing the conflict in your use case: 默认情况下，JAXB实现会将公共属性和带注释的字段视为已映射（请参阅： http ： //blog.bdoughan.com/2011/06/using-jaxbs-xmlaccessortype-to.html ），这会导致您使用冲突案件：

    this problem is related to the following location:
        at private java.lang.String nfeProc.NFe.infNFe.Endereco.pais
        at nfeProc.NFe.infNFe.Endereco
        at private nfeProc.NFe.infNFe.Endereco nfeProc.NFe.infNFe.emit.Emitente.endereco

        at private nfeProc.NFe.NFe nfeProc.NFeProc.nfe
        at nfeProc.NFeProc

Solution 解

The solution is to either annotate the get method (or set method), or annotate the field and specify @XmlAccessorType(XmlAccessType.FIELD) at the class or package level. 解决方案是注释get方法（或set方法），或者注释该字段并在类或包级别指定@XmlAccessorType(XmlAccessType.FIELD) 。
