dwr快速入门:http://directwebremoting.org/dwr/introduction/getting-started.html

jetty-maven-plugin配置:http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html

一.安装并配置好maven.新建pom.xml,导入已存在工作空间的pom工程.

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.test</groupId>
	<artifactId>testdwr</artifactId>
	<packaging>war</packaging>
	<version>1.0-SNAPSHOT</version>
	<name>testweb Maven Webapp</name>
	<url>http://maven.apache.org</url>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>
	<build>
		<pluginManagement>
			<plugins>
				<plugin>
					<groupId>org.eclipse.jetty</groupId>
					<artifactId>jetty-maven-plugin</artifactId>
					<version>9.1.2.v20140210</version>
					<configuration>
						<scanIntervalSeconds>200</scanIntervalSeconds>
						<webApp>
							<contextPath>/testdwr</contextPath>
						</webApp>
						<httpConnector>
							<port>80</port>
							<idleTimeout>60000</idleTimeout>
						</httpConnector>
					</configuration>
				</plugin>
			</plugins>
		</pluginManagement>
	</build>
	<dependencies>
		<dependency>
			<groupId>commons-logging</groupId>
			<artifactId>commons-logging</artifactId>
			<version>1.1.3</version>
		</dependency>
		<dependency>
			<groupId>org.directwebremoting</groupId>
			<artifactId>dwr</artifactId>
			<version>3.0.M1</version>
		</dependency>
	</dependencies>
</project>

二.

1.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<display-name>dwr</display-name>
	<servlet>
		<display-name>DWR Servlet</display-name>
		<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>
	</servlet>
	<servlet-mapping>
		<servlet-name>dwr-invoker</servlet-name>
		<url-pattern>/dwr/*</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	
</web-app>

2.pojo:User.java

package com.test.domain;
public class User {
	private int id;
	private String username;
	public User(int id, String username) {
		this.id=id;
		this.username=username;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
}

3.service:DwrTest.java

package com.test.web;
import com.test.domain.User;
public class DwrTest {
	public User testUser(int id,String username){
		return new User(id,username);
	}
}

4.将bean暴露出去,dwr.xml

<?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>
		<create creator="new" javascript="DwrTest">
			<param name="class" value="com.test.web.DwrTest" />
		</create>
		<convert converter="bean" match="com.test.domain.User"></convert>
	</allow>
</dwr>

5.页面:testdwr.jsp

<%@ 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 src="<%=request.getContextPath()%>/dwr/engine.js" type="text/javascript"></script>
<script src="<%=request.getContextPath()%>/dwr/util.js" type="text/javascript"></script>
<script src="<%=request.getContextPath()%>/dwr/interface/DwrTest.js" type="text/javascript"></script>
<script type="text/javascript">
	DwrTest.testUser(2,"xiejx618",function(data){
		console.log(data);
	});
	function testClick(){
		alert(dwr.util.getValue("xxx"));
	}

</script>
</head>
<body>
<input type="text" id="xxx"/>
<input type="button" value="text" onclick="testClick()"/>
</body>
</html>

6.在cmd或eclipse运行mvn jetty:run,打开chrome浏览器输入http://localhost/testdwr/testdwr.jsp  查看浏览器开发工具console
