开源项目Xstream简介4

/************* 设置类成员的别名 ***************/
//设置Person类的name成员别名Name
xStream.aliasField("Name", Person.class, "name");
/*[注意] 设置Person类的profile成员别名PROFILE,这个别名和Profile类的别名一致,
* 这样可以保持XStream对象可以从profile成员生成的xml片段直接转换为Profile成员,
* 如果成员profile的别名和Profile的别名不一致,则profile成员生成的xml片段不可
* 直接转换为Profile对象,需要重新创建XStream对象,这岂不给自己找麻烦? */
