java - XStream 双下划线处理 (Java)

Question

我想使用 XStream 将 java 类序列化为 XML。

我需要生成一个带有一个下划线 (canal_operateur) 的 XML 元素，但 XStream 在 xml 元素名称中添加了第二个下划线。

那么如何只保留一条下划线呢？

使用这个类的默认配置:

public class Document implements Serializable {
    private String typedoc;
    private Fichier fichier;
    private String canalOperateur;  
    //xstream.aliasField("canal_operateur", Document.class, "canalOperateur");
    /*
    ** setter and getter
    */
}

XStream 加倍下划线:

<document>
    <canal__operateur>canal</canal__operateur>
    <commentaire>commentaire</commentaire>
    <metadonnees/>
</document>

根据 here :

XStream maps Java class names and field names to XML tags or attributes. Unfortunately this mapping cannot be 1:1, since some characters used for identifiers in Java are invalid in XML names. Therefore XStream uses an XmlFriendlyNameCoder to replace these characters with a replacement. By default this NameCoder uses an underscore as escape character and has therefore to escape the underscore itself also. You may provide a different configured instance of the XmlFriendlyNameCoder or a complete different implementation like the NoNameCoder to prevent name coding at all. However it is your responsibility then to ensure, that the resulting names are valid for XML.
