XStream是个好东西，可以方便在Java对象和XML之间相互转换，效率和可读性都非常高，下面是我写的一个测试的例子，放出来一块看看。
需要的jar包如下：
xpp3_min-1.1.4c.jar
xstream-1.3.jar
目标：将Persons对象转换xml，再将xml转化为Persons对象。

运行测试类XStreamDemo，打印出结果：
将Java对象转换为xml！
将xml转换为Java对象！
Persons{type='001', listPerson=java.util.AbstractList$[email][email protected][/email]ractList$Itr@1cde100}
Process finished with exit code 0
呵呵，XStream不错吧！
