使XStream忽略一个特定的私有变量 [英] Make XStream ignore one specific private variable

问题描述

我正在为我正在编写保存函数的类有一点问题。

I have a little problem with a class I am currently writing a save function for.

我正在使用XStream（com.thoughtworks.xstream）来序列化一个使用DOMDriver将类转换为XML。

I'm using XStream (com.thoughtworks.xstream) to serialize a class to XML using the DOMDriver.

该类看起来像这样：

public class World {
  private Configuration config;
  public World(Configuration config) {
     this.config = config;
  }
}

所以，这里的问题是我不想要在序列化世界时序列化配置，而不是在调用fromXml（）时给XStream一个预构建的配置实例。

So, the issue here is that I do not want to serialize Configuration when serializing world, rather I'd like to give XStream a preconstructed Configuration instance when calling fromXml().

这里的问题主要是类设计，配置有一个对GUI类的私有引用因此序列化配置意味着使用GUI等完全序列化整个应用程序。这有点不好。

Problem here is mainly class design, Configuration holds a private reference to the GUI classes and therefore serializing Configuration means serializing the whole application completely with GUI etc.. And that's kind of bad.

有没有办法指示XStream不序列化私有字段配置，并在加载XStream时使用配置实例？

Is there a way to instruct XStream to not serialize the private field config, and upon load supply XStream with a configuration instance to use?

问候Daniel

推荐答案

正如文档所述： http：// x-stream.github.io/annotations-tutorial.html （省略字段）您可以使用@XStreamOmitField注释来忽略字段。

As documentation says here: http://x-stream.github.io/annotations-tutorial.html (Omitting Fields) you can use @XStreamOmitField annotation to "ignore" fields.
