Spring MVC整合DWR

http://blog.csdn.net/geloin/article/details/7537148

基本上与上文描述的情况一致；

在Controller中可以进行Service层的调用；

如果需要返回对象，需要在spring-mvc.xml中进行配置：

<dwr:configuration>
<dwr:convert type="bean"   class="com.srie.ljddml.orga.model.client.ClientUser"></dwr:convert>
</dwr:configuration>

 springmvc.xml:
