JAXB：从Java代码更改XML元素的名称？ [英] JAXB: Change name of XML Element from Java code?

问题描述

要设置XML元素的名称，我使用这样的注释：

To set the name of an XML element I use annotations like this:

@XmlElement(name = "customer_id")
public String getId(){}

我必须与两个不同的Web服务进行通信。一个表示名为 customer_id 的id元素，但另一个表示id元素的名称为 id 。我通过创建具有相同属性的第二个 Customer 类来解决问题。唯一不同的是它使用以下注释

I have to communicate with two different webservices. One expacts an id element named customer_id but the other expacts the id element to be named id. I solved the problem by creating a second Customer class with the same attributes. The only different is that it uses the following annotation

@XmlElement(name = "id")
public String getId(){}

它有一个复制构造函数，复制中的所有属性Customer1 到 Customer2 。当我与第一个webservice通信时，我发送一个 Customer1 对象，另一个webservice获取一个 Customer2 对象。

and it has a copy constructor which copies all attributes from Customer1 to Customer2. When I am communicating with the first webservice I send a Customer1 object and the other webservice gets a Customer2 object.

是否有可能只使用一个 Customer 对象，但重命名 id 属于webservice期望的任何内容？

Is there any possibility to use only one Customer object, but rename the id attribute to whatever the webservice expects?

推荐答案

注意：我是 EclipseLink JAXB（MOXy） 领导和 JAXB 2（JSR-222） 专家组。

Note: I'm the EclipseLink JAXB (MOXy) lead and a member of the JAXB 2 (JSR-222) expert group.

您可以使用MOXy JAXB中的外部映射文档扩展名将第二个映射应用于对象模型。此映射文档可用于修改通过注释提供的元数据，或完全替换它。

You can use the external mapping document extension in MOXy JAXB to apply a second mapping to your object model. This mapping document can be be used to modify metadata provided via annotations, or completely replace it.

在下面的示例中，单个对象模型映射到Google和Yahoo天气API的结果：
