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
