序列化到XML:

<?xml version="1.0" encoding="UTF-8"?>
<java version="1.7.0_45" class="java.beans.XMLDecoder">
 <object class="com.koudai.laohuji.service.User">
  <void property="aihao">
   <array class="java.lang.String" length="2">
    <void index="0">
     <string>篮球</string>
    </void>
    <void index="1">
     <string>足球</string>
    </void>
   </array>
  </void>
  <void property="id">
   <int>1</int>
  </void>
  <void property="name">
   <string>张三丰</string>
  </void>
  <void property="student">
   <object class="com.koudai.laohuji.service.Student">
    <void property="classId">
     <int>1</int>
    </void>
    <void property="level">
     <string>二年级</string>
    </void>
   </object>
  </void>
 </object>
</java>

反序列化Bean:

{id:1,name:张三丰,student:{classId:1,level:二年级},aihao:[篮球, 足球]}
