嵌入jetty到Java代码

q456123

　　在做Demo实例时，使用的jetty版本号为8.x。
　　为了避免麻烦，将全部的包都导入到MyEclipse的lib文件夹下。
　　实例1：自己定义handler的服务器
package com.jetty.test01;
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(&quot;<h1>Hello World</h1>&quot;);
}
}　　

package com.jetty.test01;
import org.eclipse.jetty.server.Server;
public class SimplestServer
{
public static void main(String[] args) throws Exception
{
Server server = new Server(8081);
server.setHandler(new HelloHandler());
server.start();
server.join();
}
}
　　訪问路径：http://localhost:8080

　　实例2：通过xml文件配置服务器
<?
　　xml version=&quot;1.0&quot;?>
<!DOCTYPE Configure PUBLIC &quot;-//Jetty//Configure//EN&quot; &quot;http://www.eclipse.org/jetty/configure.dtd&quot;>
<Configure id=&quot;FileServer&quot; class=&quot;org.eclipse.jetty.server.Server&quot;>
<Call name=&quot;addConnector&quot;>
<Arg>
<New class=&quot;org.eclipse.jetty.server.nio.SelectChannelConnector&quot;>
<Set name=&quot;port&quot;>8080</Set>
</New>
</Arg>
</Call>
<Set name=&quot;handler&quot;>
<New class=&quot;org.eclipse.jetty.server.handler.HandlerList&quot;>
<Set name=&quot;handlers&quot;>
<Array type=&quot;org.eclipse.jetty.server.Handler&quot;>
<Item>
<New class=&quot;org.eclipse.jetty.server.handler.ResourceHandler&quot;>
<Set name=&quot;directoriesListed&quot;>true</Set>
<Set name=&quot;welcomeFiles&quot;>

</Array>
</Set>
</New>
</Set>
</Configure>package com.jetty.test01;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.util.resource.Resource;
import org.eclipse.jetty.xml.XmlConfiguration;
public class FileServerXml {
public static void main(String[] args) throws Exception{
Resource fileserver_xml = Resource.newSystemResource(&quot;fileServer.xml&quot;);
XmlConfiguration configuration = new XmlConfiguration(fileserver_xml.getInputStream());
Server server = (Server)configuration.configure();
server.start();
server.join();
}
}　　訪问路径：http://localhost:8080

　　实例3：文件服务器：
package com.chinahrt.zyn.jetty;
import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.DefaultHandler;
import org.eclipse.jetty.server.handler.HandlerList;
import org.eclipse.jetty.server.handler.ResourceHandler;
import org.eclipse.jetty.server.nio.SelectChannelConnector;
public class FileServer {
public static void main(String args[]) throws Exception{
Server server = new Server();
SelectChannelConnector connector = new SelectChannelConnector();
connector.setPort(8080);
server.addConnector(connector);
ResourceHandler resource_handler = new ResourceHandler();
resource_handler.setDirectoriesListed(true);
resource_handler.setWelcomeFiles(new String[]{&quot;index.html&quot;});
resource_handler.setResourceBase(&quot;.&quot;);
HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[]{resource_handler,new DefaultHandler()});
server.setHandler(handlers);
server.start();
server.join();
}
}
　　訪问路径：http://localhost:8080

　　实例4：创建Servlet
package com.jetty.test01;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
public class OneServletContext {
public static void main(String[] args) throws Exception{
Server server = new Server(8085);
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath(&quot;/&quot;);
server.setHandler(context);
context.addServlet(new ServletHolder(new HelloServlet()), &quot;/*&quot;);
context.addServlet(new ServletHolder(new HelloServlet(&quot;Buongiorno Mondo&quot;)), &quot;/it/*&quot;);
context.addServlet(new ServletHolder(new HelloServlet(&quot;Bonjour le monde&quot;)), &quot;/fr/*&quot;);
server.start();
server.join();
}
}package com.jetty.test01;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloServlet extends HttpServlet {
private static final long serialVersionUID = 246698127519451952L;
private String greeting=&quot;Hello World&quot;;
public HelloServlet(){}
public HelloServlet(String greeting){
this.greeting = greeting;
}
protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
{
response.setContentType(&quot;text/html&quot;);
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().println(&quot;<h1>&quot;+greeting+&quot;</h1>&quot;);
response.getWriter().println(&quot;session=&quot;+request.getSession(true).getId());
}
}
