JAXB。自定义字段命名行为（camelCase为underscore_case） [英] Jaxb. Customize field naming behavior(camelCase to underscore_case)

问题描述

我想用强调名称序列化我的字段。例如： userName - > user_name 。

I want to serialize my fields with underscored names. For example: userName -> user_name.

我知道可以使用 @XmlElement（name =user_name）注释完成，但它是对我来说不是很方便。

I know that it can be done with the @XmlElement(name = "user_name") annotation, but it's not very handy for my case.

有没有办法为JAXB设置默认命名策略？

Is there any way to set up a default naming policy for JAXB?

推荐答案

注意：我是EclipseLink JAXB（MOXy）的负责人，也是JAXB（JSR-222）专家组的成员。

MOXy的 XMLNameTransformer 扩展，使您可以覆盖元素，属性和类型的默认命名策略。

MOXy has an XMLNameTransformer extension that enables you to override the default naming policy for elements, attributes, and types.

如果您是从XML架构生成模型，则可以使用保留下划线的外部绑定文件。

If you generated your model from an XML schema you can use an external binding file to keep the underscores.

<?xml version="1.0" encoding="UTF-8"?>
<jxb:bindings 
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
  version="2.1">
  <jxb:globalBindings underscoreBinding="asCharInWord"/>
</jxb:bindings>
