spring整合DWR步骤简单说明

一、导入dwr包【dwr.jar】并在web.xml中添加如下代码

<listener>
		<listener-class>org.directwebremoting.servlet.DwrListener</listener-class>
	</listener>

	<servlet>
		<servlet-name>dwr-invoker</servlet-name>
		<servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>

		<init-param>
			<param-name>debug</param-name>
			<param-value>true</param-value>
		</init-param>

		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>dwr-invoker</servlet-name>
		<url-pattern>/dwr/*</url-pattern>
	</servlet-mapping>

二、编写service类，如下

package cn.com.songjy.service;

import org.springframework.stereotype.Service;

@Service("dwrService")
public class DwrService {

	public String hello(String name){
		return "你好," + name;
	}
	
	public String hello_1(String name){
		return "Hello," + name;
	}
	
	public String getName(String name){
		
		return name;
	}
	
}

三、在WEB-INF目录下创建dwr.xml文件，如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 3.0//EN" "http://getahead.org/dwr/dwr30.dtd">

<dwr>

	<allow>
		
		<!-- DwrServiceJs是页面引用时要用到的名称 -->
		<create creator="spring" javascript="DwrServiceJs">
			<!-- dwrService是spring注入cn.com.songjy.service.DwrService类时名称 -->
			<param name="beanName" value="dwrService" />
			<!-- 对外公布方法列表，当须全部公布时，则无需配置include -->
			<include method="hello"/>
			<include method="hello_1"/>
		</create>

	</allow>

</dwr>

四、编写页面脚本测试【dwr.jsp】，如下

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<script type="text/javascript" src="<%=request.getContextPath()%>/dwr/engine.js"></script>
<script type="text/javascript" src="<%=request.getContextPath()%>/dwr/interface/DwrServiceJs.js"></script>
</head>
<script type="text/javascript">
	DwrServiceJs.hello("张三", function(data){
			alert(data);
	});
</script>
<body>

</body>
</html>

最后访问【dwr.jsp】即可测试！
