Jetty實戰之 嵌入式運行Jetty

Jetty最常用的一種用法是把Jetty嵌入到自己的Java應用程序中，此時Jetty作為一個后臺的Servlet容器運行，接受用戶的http請求，下面是一個最簡單的嵌入Jetty的用法。

1. 首先使用Maven創建一個java工程

mvn archetype:generate -DgroupId=com.google.code.garbagecan.jettystudy -DartifactId=jettystudy -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

2. 修改pom文件，添加或修改編譯和依賴部分

<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>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

3. 創建一個Server類，用了啟動Jetty server，并且通過一個HelloHandler來處理瀏覽器發送過來的請求；

package com.google.code.garbagecan.jettystudy.sample1;

import org.eclipse.jetty.server.Server;

public class MyServer {
    public static void main(String[] args) throws Exception {
        Server server = new Server(8080);
        server.setHandler(new HelloHandler());

        server.start();
        server.join();
    }
}

4. 創建一個Handler類，用了處理所有客戶端的請求

package com.google.code.garbagecan.jettystudy.sample1;

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 HelloHandler 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("Request url: " + target);
    }
}

5. 運行MyServer類，然后通過瀏覽器訪問http://localhost:8080/，可以看到“Hello World！”和請求的url。
