二、Main代码package my.restful;

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 Main {

public static void main(String[] args) throws Exception {
Server server=new Server(8080);
//////////////////////////ServletHolder////////////////////////////////
ServletHolder servlet = new ServletHolder(ServletContainer.class);
servlet.setInitParameter("com.sun.jersey.config.property.resourceConfigClass",
"com.sun.jersey.api.core.PackagesResourceConfig");
servlet.setInitParameter("com.sun.jersey.config.property.packages", "my.restful");
/////////////////////////ServletContextHandler//////////////////////////////////////////
ServletContextHandler handler = new ServletContextHandler(ServletContextHandler.SESSIONS);
handler.setContextPath("/");
handler.addServlet(servlet, "/*");
////////////////////////////////////////
server.setHandler(handler);
server.start();
//////////////////////////////////////
System.out.println("JettyStart at 127.0.0.1:8080");
}
}

三、资源类代码package my.restful;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

/**
* Root resource (exposed at "myresource" path)
*/
@Path("myresource")
public class MyResource {

/**
* Method handling HTTP GET requests. The returned object will be sent
* to the client as "text/plain" media type.
*
* @return String that will be returned as a text/plain response.
*/
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getIt() {
return "Got it!";
}
}
