另一种方法

将PersonBean 中的

 @XStreamAlias("friends")

    privateFriends friend;




改成

 @XStreamAlias("friends")

    privateList<Strinng> friend;

      java对象转换成xml时加个

xstream.alias("name", String.class);也可以实现


 <friends>

    <name>A1</name>

    <name>A2</name>

    <name>A3</name>

  </friends>

这种效果
