Dwr的ScriptSessionListener使用，监听ScriptSessionListener的产生，消亡（1）

由于时间紧迫，本人只记录关键部分代码，不明白的可以询问,例子封装的不是很好，只代表明白意思即可，

 标注红色的要注意

dwr.xml

 

<dwr>
  <allow>
    <create creator="new" javascript="UserService">
      <param name="class" value="com.huawei.service.UserService"/>
    </create>
    <convert converter="bean" match="com.huawei.model.User"/>
  </allow>
</dwr>
