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

<!---->xml version="1.0" encoding="UTF-8"?>

        "http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
    <allow>
        <create creator="spring" javascript="UserDAO">
            <param name="beanName" value="userDao"/>
            <include method="addUser"/>
            <include method="removeUser"/>
            <include method="findUserByName"/>
        create>
         <convert converter="bean" match="martin.dwr.demo.model.User">
            <param name="include" value="id,name,password,age"/>
        convert>
    allow>
dwr>

 

<o:p>

web.xml<o:p></o:p>代码

<!---->xml version="1.0" encoding="UTF-8"?>

        "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>/WEB-INF/classes/applicationContext.xmlparam-value>
    context-param>
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        listener-class>
    listener>
    <servlet>
        <servlet-name>dwr-invokerservlet-name>
        <servlet-class>uk.ltd.getahead.dwr.DWRServletservlet-class>
        <init-param>
            <param-name>debugparam-name>
            <param-value>trueparam-value>
        init-param>
        <init-param>
            <param-name>config-adminparam-name>

    <servlet-mapping>
       <servlet-name>dwr-invokerservlet-name>
        <url-pattern>/dwr/*url-pattern>
    servlet-mapping>
web-app>

 

applicationContext.xml<o:p></o:p>代码

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

 

2、dwr与struts的集成问题。<o:p></o:p>

   Dwr.xml代码

<o:p>

<dwr>
    <allow>
        <convert converter="bean" match="dwr.demo.Goods"/>
        <create creator="new" javascript="DemoAction" class="dwr.demo.DemoAction">
            <include method="query4dwr"/>
            <include method="copy4dwr"/>
            <include method="paste4dwr"/>
        create>
        <create creator="new" javascript="DemoFacade" class="dwr.demo.DemoFacade">
            <include method="queryList"/>
            <include method="restore"/>
            <include method="del"/>
        create>
      allow>
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？

小弟对DWR也是刚刚接触，还请boin大哥多多指点！

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) {
	}
}
