java - 如何使用 XStream 库轻松序列化对象中的 xml 文件

Question

我有以下 xml 文件:

    <?xml version="1.0" encoding="UTF-8"?>
<!--

    This is a sample netbeans project file for a Squawk project.
    You may edit it freely, it doesn't affect the ant-powered build.

 -->

我想用java和Xstream库(序列化)解析它，以更改某些属性和节点的值，然后将其反序列化到文件中。但是我发现将java类制作为处理所有这些节点(我必须为每个节点创建一个java类，例如:1个类，然后1个类等...)。我发现这有点浪费时间。有没有其他方法可以更快地做到这一点更少的代码。或者也许我对库的工作方式理解有问题？ 谢谢

如果您想控制用于序列化的 XML(或已定义 XML 架构)，您可以实现转换器类。 但如果您接受默认编码(或者可能只是稍微调整一下)，XStream 是最容易使用的。然后您需要很少的编码 - 但您必须接受它生成的 XML。
