SpringMVC的maven项目创建可以参考这篇文章：http://www.cnblogs.com/crazy-fox/archive/2012/02/18/2357619.html


建立一个SpringMVC项目如下：

2.web.xml: 

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  
  <servlet>
        <servlet-name>mvcServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        
        <init-param>

    <servlet-mapping>
        <servlet-name>mvcServlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
  
</web-app>
Spring-mvc缺省是在WEB-INF目录下找名称未${servlet-name}-context.xml的配置文件，这里通过contextconfiglocation的配置，将spring-mvc所需的配置文件指向到src\resources\spring\web目录下。


3.servlet-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" 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"
    xsi:schemaLocation="

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
">
    <context:component-scan base-package="com.kxw.springmvc.controller" />
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

4.Controller类HelloWorld.java: 

package com.kxw.springmvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/helloworld")
public class Helloworld {

    @RequestMapping(method=RequestMethod.GET)
    public ModelAndView hello() {
        ModelAndView mv = new ModelAndView();
        mv.setViewName("helloworld");
        return mv;
    }
}

5.helloworld.jsp: 

<%@page contentType="text/html" 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>JSP Page</title>
    </head>
    <body>
        <h1>Hello World!</h1>
    </body>
</html>


6.webdefault.xml:

可去下载jetty-distribution-7.6.12.v20130726.zip,里面便有这个文件


7.运行mvn jetty:run 启动工程后，访问http://localhost:7878/springmvc/helloworld.action ,可以看到Hello World!


创建一个SpringMVC项目之后，接下来来整合DWR

可参考此文章：http://blog.csdn.net/geloin/article/details/7537148

SpringMVC整合DWR(Maven项目+jetty插件运行)

1.导入DWR包和其他必须包,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">

    </dependency>
    
    <dependency>

    </configuration>
</plugin>
        
    </plugins>
    
  </build>
</project>


2.在web.xml中配置dwr。只需在配置DispatcherServlet下添加dwr的url-mapping即可，修改后的DispatcherServlet配置如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:web="http://xmlns.jcp.org/xml/ns/javaee">
  <display-name>Archetype Created Web Application</display-name>
  <servlet>
    <servlet-name>mvcServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>mvcServlet</servlet-name>
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>mvcServlet</servlet-name>
    <url-pattern>/dwr/*</url-pattern>
  </servlet-mapping>
</web-app>

3.在servlet-context.xml中添加dwr的配置，修改后的文件如下所示： 

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

4.Controller类： 

package com.kxw.dwr.model;


import java.util.ArrayList;
import java.util.List;

import org.directwebremoting.annotations.RemoteMethod;
import org.directwebremoting.annotations.RemoteProxy;
import org.springframework.stereotype.Controller;


@Controller  
@RemoteProxy(name="MyDwr")
public class MyDwr {

	@RemoteMethod
	public String hello(String world){
		
		System.out.println("hello"+world);
		
		return "hello"+world;
	}
	
	@RemoteMethod
	public User load(){
		
		User user=new User(10,"Messi",new Group(1,"Bacelona FC"));

	}
	
	@RemoteMethod

	}
	@RemoteMethod
	public void add(User user){
		
		System.out.println(user);
	}
	@RemoteMethod
	public void deleteUser(){
		throw new MyException("删除用户！！");
	}
	@RemoteMethod
	public int add(int a,int b){
		
		return a+b;
	}
}


package com.kxw.dwr.model;

public class User {

	private int id;

	private Group group;
	
	public User(int id, String username, Group group) {

	}


	@Override
	public String toString() {

	}


	@Override
	public String toString() {

	}

	
}

5.dwr.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"

		alert(users[i].username+","+users[i].group.name);
	}
	
}
</script>
</head>
<body>

</body>
</html>

6.运行项目run:jetty

在浏览器敲入：http://localhost:7878/springmvc_dwr/dwr.jsp

SpringMVC整合DWR(Maven项目+jetty插件运行)SpringMVC整合DWR(Maven项目+jetty插件运行)

连续显示四个对话框

---------------------------------------------------------------------------------------------

Ps:若出现此异常：

原文：http://10000001.blog.51cto.com/4600383/1340559

Spring整合Dwr,Cannot locate BeanDefinitionParser for element [annotation-scan]

原因是Maven下的dwr版本不适合，要去DWR官网http://directwebremoting.org/dwr/downloads/index.html#maven

下载jar包，把Maven仓库下面的dwr换为官网的，

这样就没问题了，自己感觉是Maven中心仓库里不支持吧。



----------------

servlet与dwr的配置分开两个配置文件，否则老是失败
