1. 首先修改pom.xml文件，添加spring的依赖项

[html]   view plain copy print ?

1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
2.     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  
3.     <modelVersion>4.0.0</modelVersion>

6.     <packaging>jar</packaging>  
7.     <version>1.0-SNAPSHOT</version>

20.             </plugin>  
21.         </plugins>  
22.     </build>

44.             <scope>test</scope>  
45.         </dependency>  
46.     </dependencies>  
47. </project>  

2. 建立一个Server类，用来经过spring来启动Jetty server

[java]   view plain copy print ?

1. package com.google.code.garbagecan.jettystudy.sample4;  
2.   
3. import org.springframework.context.support.ClassPathXmlApplicationContext;  
4.   
5. public class MyServer {  
6.     public static void main(String[] args) throws Exception {  
7.         new ClassPathXmlApplicationContext("/com/google/code/garbagecan/jettystudy/sample4/spring.xml");  
8.     }  
9. }  

3. 建立一个Handler类，用了处理http请求

[java]   view plain copy print ?

1. package com.google.code.garbagecan.jettystudy.sample4;  
2.   
3. import java.io.IOException;  
4.   
5. import javax.servlet.ServletException;  
6. import javax.servlet.http.HttpServletRequest;  
7. import javax.servlet.http.HttpServletResponse;  
8.   
9. import org.eclipse.jetty.server.Request;  
10. import org.eclipse.jetty.server.handler.AbstractHandler;  
11.   
12. public class MyHandler extends AbstractHandler {  
13.     public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response)  
14.             throws IOException, ServletException {  
15.         response.setContentType("text/html;charset=utf-8");  
16.         response.setStatus(HttpServletResponse.SC_OK);  
17.         baseRequest.setHandled(true);  
18.         response.getWriter().println("<h1>Hello World</h1>");  
19.         response.getWriter().println("<li>Request url: " + target + "</li>");  
20.         response.getWriter().println("<li>Server port: " + request.getServerPort() + "</li>");  
21.     }  
22. }  

4. 建立一个spring配置文件，并放在com/google/code/garbagecan/jettystudy/sample4/spring.xml位置，内容以下.

[java]   view plain copy print ?

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <beans xmlns="http://www.springframework.org/schema/beans"  
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
4.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">  
5.   
6.     <bean id="Server" class="org.eclipse.jetty.server.Server" init-method="start" destroy-method="stop">  
7.         <property name="connectors">  
8.             <list>  
9.                 <bean id="Connector" class="org.eclipse.jetty.server.nio.SelectChannelConnector">  
10.                     <property name="port" value="8080" />  
11.                 </bean>  
12.             </list>  
13.         </property>  
14.   
15.         <property name="handler">  
16.             <bean id="handlers" class="org.eclipse.jetty.server.handler.HandlerList">  
17.                 <property name="handlers">  
18.                     <list>  
19.                         <bean class="com.google.code.garbagecan.jettystudy.sample4.MyHandler" />  
20.                         <bean class="org.eclipse.jetty.server.handler.DefaultHandler" />  
21.                     </list>  
22.                 </property>  
23.             </bean>  
24.         </property>  
25.     </bean>  
26. </beans>  

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