写一个JettyServer

package com.demo.jetty;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.servlet.ServletContextHandler;import org.eclipse.jetty.servlet.ServletHolder;import com.sun.jersey.spi.container.servlet.ServletContainer;public class JettyServer {private void start() throws Exception {int port = 8080;Server server = new Server(port);ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);context.setContextPath("/");server.setHandler(context);ServletHolder sh = new ServletHolder(ServletContainer.class);sh.setInitParameter("com.sun.jersey.config.property.resourceConfigClass","com.sun.jersey.api.core.PackagesResourceConfig");sh.setInitParameter("com.sun.jersey.config.property.packages","com.demo.rest");context.addServlet(sh, "/*");server.start();}public void stop() throws Exception {}public static void main(String[] args) throws Exception {JettyServer server = new JettyServer();server.start();}}

写一个java resource类

package com.demo.rest;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;@Path("/welcome")public class WelcomeResource {@GET@Produces(MediaType.TEXT_PLAIN)public String sayHello() {return "Welcome to Jersey world";}}

启动JettyServer，浏览器输入http://localhost:8080/welcome，结果如下图：
