java - 两个子元素中的 JAXB 序列化

Question

类(class):

public class OddEvenSettings {
  int oddSetting1;
  int oddSetting2;
  int evenSetting1;
  int evenSetting2;
}

所需的 XML

<OddEvenSettings>
  <odd setting1="0" setting2="0"/>
  <even setting1="0" setting2="0"/>
</OddEvenSettings>

我应该如何注释类以在序列化后获取 XML(使用 JAXB RI)？

Answer 1

注意:我是EclipseLink JAXB (MOXy) JAXB (JSR-222) 的领导者和成员专家组。

对于此用例，您可以使用 MOXy 的 @XmlPath 扩展:

import javax.xml.bind.annotation.*;
import org.eclipse.persistence.oxm.annotations.*;

@XmlRootElement("OddEvenSettings")
@XmlAccessorType(XmlAccessType.FIELD)
public class OddEvenSettings {
  @XmlPath("odd/@setting1")
  int oddSetting1;

  @XmlPath("odd/@setting2")
  int oddSetting2;

  @XmlPath("even/@setting1")
  int evenSetting1;

  @XmlPath("even/@setting2")
  int evenSetting2;
}
