DWR使用过程中的几个问题

1、dwr与spring的集成。

<o:p>

dwr.xml<o:p></o:p>代码

1. <!---->xml version="1.0" encoding="UTF-8"?>    
2.   
3.         "http://www.getahead.ltd.uk/dwr/dwr10.dtd">    
4. <dwr>    
5.     <allow>   
6.         <create creator="spring" javascript="UserDAO">  
7.             <param name="beanName" value="userDao"/>  
8.             <include method="addUser"/>   
9.             <include method="removeUser"/>  
10.             <include method="findUserByName"/>  
11.         create>  
12.          <convert converter="bean" match="martin.dwr.demo.model.User">  
13.             <param name="include" value="id,name,password,age"/>  
14.         convert>    
15.     allow>  
16. dwr>  
17.   

 

<o:p>

web.xml<o:p></o:p>代码

1. <!---->xml version="1.0" encoding="UTF-8"?>  
3.         "http://java.sun.com/dtd/web-app_2_3.dtd">  
4. <web-app>  
5.     <context-param>  
6.         <param-name>contextConfigLocationparam-name>

14.     <servlet>

28.         <url-pattern>/dwr/*url-pattern>  
29.     servlet-mapping>  
30. web-app>  

 

applicationContext.xml<o:p></o:p>代码

1. <bean id="userDao" class="martin.dwr.demo.dao.hibernate.HibernateUserDAO">  
2.         <property name="sessionFactory" ref="sessionFactory"/>  
3.     </bean>  

 

2、dwr与struts的集成问题。<o:p></o:p>

   Dwr.xml代码

<o:p>

1. <dwr>  
2.     <allow>  
3.         <convert converter="bean" match="dwr.demo.Goods"/>  
4.         <create creator="new" javascript="DemoAction" class="dwr.demo.DemoAction">  
5.             <include method="query4dwr"/>  
6.             <include method="copy4dwr"/>  
7.             <include method="paste4dwr"/>  
8.         create>  
9.         <create creator="new" javascript="DemoFacade" class="dwr.demo.DemoFacade">  
10.             <include method="queryList"/>  
11.             <include method="restore"/>  
12.             <include method="del"/>  
13.         create>  
14.       allow>  
15. dwr>  

</o:p></o:p></o:p>  

      这里建议直接使用DAO的方法，直接在View层中调用DAO，破坏了程序的层次；利用action进行统一的处理，会不会有生产js的效率问题，是否可以新建一个dwr的 包让View直接与其通信？

DWR也属于VIEW层，个人在应用中使用DWR Annotation，和AjaxService来进行通信。

@RemoteProxy(creator = SpringCreator.class, name = "Service", creatorParams = @Param(name = "beanName", value = "AjaxService"))
public class AjaxDWRService extends AjaxService {
		
	public AjaxDWRService() {
	}

	@RemoteMethod
	public List getRoles(String depname) {
	}

	@RemoteMethod
	public List getModNmames() {
	}

	@RemoteMethod
	public List getModule(int moduleId) {
	}
}

小弟对DWR也是刚刚接触，还请boin大哥多多指点！
