1. 首先修改pom.xml文件，添加spring的依赖项

写道

<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>

</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>org.eclipse.jetty.aggregate</groupId>
<artifactId>jetty-all</artifactId>
<version>8.0.4.v20111024</version>

<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

    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

    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.

写道

<?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。
