Make sure you have included all the jars that come with XStream also specially "kxml2.jar" and "xmlpull-1.1.3.1.jar" file. Jar version may deffer incase of yours.
确保您已经包含了 XStream 附带的所有 jar，特别是“kxml2.jar”和“xmlpull-1.1.3.1.jar”文件。Jar 版本可能会延迟以防万一。

Use
用
new XStream(new StaxDriver())
xpp and xmlpull are very old codebases
xpp 和 xmlpull 是非常古老的代码库
with non-default constructor you could avoid those 2 jars
使用非默认构造函数，您可以避免使用这两个 jar
