1. 首先修改pom.xml文件，添加spring的依赖项

    <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>4.0.0modelVersion>

1. 创建一个Server类，用来通过spring来启动Jetty server

    package com.google.code.garbagecan.jettystudy.sample4;  

    import org.springframework.context.support.ClassPathXmlApplicationContext;  

    public class MyServer {  
        public static void main(String[] args) throws Exception {  
            new ClassPathXmlApplicationContext("/com/google/code/garbagecan/jettystudy/sample4/spring.xml");  
        }  
    }  

1. 创建一个Handler类，用了处理http请求

  package com.google.code.garbagecan.jettystudy.sample4;  

    import java.io.IOException;  

    import javax.servlet.ServletException;  
    import javax.servlet.http.HttpServletRequest;  
    import javax.servlet.http.HttpServletResponse;  

    import org.eclipse.jetty.server.Request;  
    import org.eclipse.jetty.server.handler.AbstractHandler;  

    public class MyHandler extends AbstractHandler {  
        public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response)  
                throws IOException, ServletException {  
            response.setContentType("text/html;charset=utf-8");  
            response.setStatus(HttpServletResponse.SC_OK);  
            baseRequest.setHandled(true);  
            response.getWriter().println("
Hello World
");  
            response.getWriter().println("
Request url: " + target + "
");  
            response.getWriter().println("
Server port: " + request.getServerPort() + "
");  
        }  
    }  

1. 创建一个spring配置文件，并放在com/google/code/garbagecan/jettystudy/sample4/spring.xml位置，内容如下.

      
    <beans xmlns="http://www.springframework.org/schema/beans"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">  

        <bean id="Server" class="org.eclipse.jetty.server.Server" init-method="start" destroy-method="stop">  
            <property name="connectors">  
                <list>  
                    <bean id="Connector" class="org.eclipse.jetty.server.nio.SelectChannelConnector">  
                        <property name="port" value="8080" />  
                    bean>  
                list>  
            property>  

            <property name="handler">  
                <bean id="handlers" class="org.eclipse.jetty.server.handler.HandlerList">  
                    <property name="handlers">  
                        <list>  
                            <bean class="com.google.code.garbagecan.jettystudy.sample4.MyHandler" />  
                            <bean class="org.eclipse.jetty.server.handler.DefaultHandler" />  
                        list>  
                    property>  
                bean>  
            property>  
        bean>  
    beans>  

其中定义了Jetty Server的配置，包括Connector和Handler等等。
5. 运行MyServer类，然后通过http://localhost:8080/来访问。
