spring3整合dwr3-CFANZ编程社区

1.web.xml中加入dwr配置如下：

<!-- dwr 配置 -->
	<servlet>
		<servlet-name>dwr</servlet-name>
		<servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>
		<init-param>
			<param-name>debug</param-name>
			<param-value>true</param-value>
		</init-param>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>dwr</servlet-name>
		<url-pattern>/dwr/*</url-pattern>
	</servlet-mapping>

2.由spring接管dwr,配置spring的xml文件如下:

spring的xml中开头namespace加上drw标签配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
 http://www.springframework.org/schema/aop 
 http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
 http://www.springframework.org/schema/tx 
 http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
 http://www.directwebremoting.org/schema/spring-dwr
 http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd
 http://www.springframework.org/schema/context 
 http://www.springframework.org/schema/context/spring-context-3.0.xsd" default-autowire="byName">

spring中配置dwr,如下：

<!-- dwr 配置 -->
	<!-- 注意这里新增加的dwr tag, 为使其生效，文件头中要声明namespace -->
	<dwr:configuration>
		<dwr:convert type="bean" class="com.myweb.modal.ibatis.Month" />
	</dwr:configuration>
	<!-- 扫描读取注解加载的类 -->    
    <dwr:annotation-scan scanRemoteProxy="true" base-package="com.myweb.service" /> 
	<dwr:url-mapping />

	<!-- 部署项目时, 请把debug设为false -->
	<dwr:controller id="dwrController" debug="true" />

3.配置dwr的service:

package com.myweb.service;
import java.util.List;

import org.directwebremoting.annotations.RemoteMethod;
import org.directwebremoting.annotations.RemoteProxy;
import org.directwebremoting.spring.SpringCreator;
import org.springframework.beans.factory.annotation.Autowired;

import com.myweb.modal.ibatis.Month;
@RemoteProxy(creator=SpringCreator.class)
public class TestDwrService {
	
	@Autowired
	private MonthService monthService;
	
	@RemoteMethod
	public List<Month> test(){
		List<Month> months = monthService.findIMonths();
		return months;
	}
	
}

4.配置页面：

<!-- struts2不推荐使用JSTL，如果要使用el表达式，请注意加入isELIgnored="false" -->
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" isELIgnored="false"%>
<%@ include file="/common/taglib.jsp"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<script type='text/javascript' src='${ctxPath}/dwr/engine.js'></script>
<script type='text/javascript' src='${ctxPath}/dwr/util.js'></script>
<script type='text/javascript' src='${ctxPath}/dwr/interface/TestDwrService.js'></script>
</head>
<body>


<a href="javascript:testDwr();">测试dwr</a>


</body>
<script type="text/javascript">
	function testDwr(){
		TestDwrService.test(function(data){
			var detail = '';
			for(var i=0;i<data.length;i++){
			 	detail = detail + data[i].name+"花费:"+data[i].total+"元\r\n"		
			}		
			alert(detail);
		});		
	}
</script>
</html>
