Dwr的ScriptSessionListener运用，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>
