嵌入jetty到Java代码
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("<h1>Hello World</h1>");
}
}
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="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure id="FileServer" class="org.eclipse.jetty.server.Server">
<Call name="addConnector">
<Arg>
<New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
<Set name="port">8080</Set>
</New>
</Arg>
</Call>
<Set name="handler">
<New class="org.eclipse.jetty.server.handler.HandlerList">
<Set name="handlers">
<Array type="org.eclipse.jetty.server.Handler">
<Item>
<New class="org.eclipse.jetty.server.handler.ResourceHandler">
<Set name="directoriesListed">true</Set>

</Array>
</Set>
<Set name="resourceBase">.</Set>
</New>
</Item>
<Item>
<New class="org.eclipse.jetty.server.handler.DefaultHandler">
</New>
</Item>
</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("fileServer.xml");
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[]{"index.html"});
resource_handler.setResourceBase(".");
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("/");
server.setHandler(context);
context.addServlet(new ServletHolder(new HelloServlet()), "/*");
context.addServlet(new ServletHolder(new HelloServlet("Buongiorno Mondo")), "/it/*");
context.addServlet(new ServletHolder(new HelloServlet("Bonjour le monde")), "/fr/*");
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="Hello World";
public HelloServlet(){}
public HelloServlet(String greeting){
this.greeting = greeting;
}
protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
{
response.setContentType("text/html");
response.setStatus(HttpServletResponse.SC_OK);
response.getWriter().println("<h1>"+greeting+"</h1>");
response.getWriter().println("session="+request.getSession(true).getId());
}
}
訪问路径：http://localhost:8080/，http://localhost:8080/it，http://localhost:8080/fr
