Java 通过XSTREAM在XML中添加不需要的元素

我是XStream的新手

我有以下的DTO

@XStreamAlias("outline")
public class OutlineItem implements java.io.Serializable {

    private static final long serialVersionUID = -2321669186524783800L;

    @XStreamAlias("text")
    @XStreamAsAttribute
    private String text;

    @XStreamAlias("removeMe")
    private List<OutlineItem> childItems;
}

我把它作为我的输出文本

<outline text="Test">
  <removeMe>
    <outline text="Test Section1">
      <removeMe>
        <outline text="Sub Section1 1">
          <removeMe/>
        </outline>
        <outline text="Sub Section1 2">
          <removeMe/>
        </outline>
      </removeMe>
    </outline>
    <outline text="Test Section 2">
      <removeMe>
        <outline text="Test Section2 1">
          <removeMe/>
        </outline>
      </removeMe>
    </outline>
  </removeMe>
</outline>

鉴于我希望输出为：

<outline text="Test">
    <outline text="Test Section1">
        <outline text="Sub Section1 1">
        </outline>
        <outline text="Sub Section1 2">
        </outline>
    </outline>
    <outline text="Test Section 2">
        <outline text="Test Section2 1">
        </outline>
    </outline>
</outline>

任何帮助都将不胜感激！不确定是否需要某种XSLT

注意：我是负责人，也是JAXB（）专家组的成员

我相信答案是：

@XStreamImplicit(itemFieldName="outline")
private List<OutlineItem> childItems;

谢谢你的解决方案。它工作得很好。我还将研究JAXB。

@XStreamImplicit(itemFieldName="outline")
private List<OutlineItem> childItems;

import javax.xml.bind.annotation.*;

@XmlRootElement(name="outline")
@XmlAccessorType(XmlAccessType.FIELD)
public class OutlineItem implements java.io.Serializable {

    private static final long serialVersionUID = -2321669186524783800L;

    @XmlAttribute
    private String text;

    @XmlElement("outline")
    private List<OutlineItem> childItems;

}

import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws JAXBException {

        JAXBContext jaxbContext = JAXBContext.newInstance(OutlineItem.class);

        Marshaller marshaller = jaxbContext.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(outlineItem, System.out);

    }

}
