Jetty实战(4)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。
