Jetty实战之 嵌入式Jetty集成Spring运行

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>4.0.0</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

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.

<?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。
