使用xstream定制java集合的序列化 [英] customising serialisation of java collections using xstream

问题描述

我有一个对象需要序列化为XML，其中包含以下字段：

  List< String& tags = new List< String>（）; 
 

XStream序列化正好（在某些别名之后），如下所示：

 < tags> 
< string> tagOne< / string> 
< string> tagTwo< / string> 
< string> tagThree< / string> 
< string> tagFour< / string> 
< / tags> 
  

这样没问题，但我想能够重命名< string> 元素，例如< tag> 。我看不到一个明显的方法来做这个从XStream网站上的别名文档。 我建议修改 List< String> 到 List< Tag> ，其中Tag是一个基本上只包含字符串的域对象。然后你说：

  xstream.alias（tag，org.goring.Tag.class）; 
  

，你会得到你想要的。这避免了滚动自己的Converter。

I have an object that needs to be serialised as XML, which contains the following field:

List<String> tags = new List<String>();

XStream serialises it just fine (after some aliases) like this:

<tags>
  <string>tagOne</string>
  <string>tagTwo</string>
  <string>tagThree</string>
  <string>tagFour</string>
</tags>

That's OK as far as it goes, but I'd like to be able to rename the <string> elements to, say, <tag>. I can't see an obvious way to do that from the alias documentation on the XStream site. Am I missing something obvious?

解决方案

I'd suggest changing the List<String> to a List<Tag>, where Tag is a domain object that essentially just contains a String. Then you say:

xstream.alias("tag", org.goring.Tag.class);

and you get exactly what you want. This avoids having to roll your own Converter.
