Jetty的配置、部署與API使用——（3）Linux下利用Jetty API執行一個Jetty伺服器

1. 下載Jetty的Java歸檔檔案

mkdir Demo
cd Demo
JETTY_VERSION=7.0.2.v20100331
wget -U none http://repo1.maven.org/maven2/org/eclipse/jetty/aggregate/jetty-all/$JETTY_VERSION/jetty-all-$JETTY_VERSION.jar
wget -U none http://repo1.maven.org/maven2/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar

2. 編寫源程式

這裡同上一篇文章。

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
 
import java.io.IOException;
 
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.Request;
import org.eclipse.jetty.server.handler.AbstractHandler;
 
public class HelloWorld 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>");
    }
 
    public static void main(String[] args) throws Exception
    {
        Server server = new Server(8080);
        server.setHandler(new HelloWorld());
 
        server.start();
        server.join();
    }
}

3. 編譯

javac -cp servlet-api-2.5.jar:jetty-all-$JETTY_VERSION.jar HelloWorld.java

4. 執行

java -cp .:servlet-api-2.5.jar:jetty-all-$JETTY_VERSION.jar HelloWorld
