1. 首先修改pom.xml文件，添加spring的依赖项

[html] view
plain copy

<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.google.code.garbagecan.jettystudy</groupId>  

    <artifactId>jettystudy</artifactId>  

    <packaging>jar</packaging>  

    <version>1.0-SNAPSHOT</version>  

    <name>jettystudy</name>  

    <url>http://maven.apache.org</url>  

    <build>  

        <plugins>  

            <plugin>  

                <artifactId>maven-compiler-plugin</artifactId>  

                <inherited>true</inherited>  

                <configuration>  

                    <source>1.6</source>  

                    <target>1.6</target>  

                    <debug>true</debug>  

                </configuration>  

            </plugin>  

        </plugins>  

    </build>  

    <dependencies>  

        <dependency>  

            <groupId>org.eclipse.jetty.aggregate</groupId>  

            <artifactId>jetty-all</artifactId>  

            <version>8.0.4.v20111024</version>  

            <type>jar</type>  

            <scope>provided</scope>  

        </dependency>  

          

        <dependency>  

            <groupId>org.springframework</groupId>  

            <artifactId>spring</artifactId>  

            <version>2.5.6</version>  

            <type>jar</type>  

            <scope>provided</scope>  

        </dependency>  

          

        <dependency>  

            <groupId>junit</groupId>  

            <artifactId>junit</artifactId>  

            <version>3.8.1</version>  

            <scope>test</scope>  

        </dependency>  

    </dependencies>  

</project>  

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

[java] view
plain copy

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");  

    }  

}  

3. 创建一个Handler类，用了处理http请求

[java] view
plain copy

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("<h1>Hello World</h1>");  

        response.getWriter().println("<li>Request url: " + target + "</li>");  

        response.getWriter().println("<li>Server port: " + request.getServerPort() + "</li>");  

    }  

}  

4. 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.

[java] view
plain copy

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

<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。
