Jetty之HelloWorld
1.准备工作：
Jetty下载地址：http://dist.codehaus.org/jetty/jetty-hightide-8.1.14/
Jetty源码下载地址：http://dev.eclipse.org/svnroot/rt/org.eclipse.jetty/jetty
添加的jar包：
jetty-continuation-8.1.14.v20131031.jar jetty-http-8.1.14.v20131031.jar jetty-io-8.1.14.v20131031.jar jetty-security-8.1.14.v20131031.jar jetty-server-8.1.14.v20131031.jar jetty-servlet-8.1.14.v20131031.jar jetty-util-8.1.14.v20131031.jar servlet-api-3.0.jar
添加以下三个jar，为了能看到启动日志：
logback-classic-1.0.9.jar logback-core-1.0.9.jar slf4j-api-1.7.2.jar
2.上传demo：
package com.potter.test;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;

public class TestServletServer {
public static void main(String[] args) throws Exception{
Server server=new Server(8080);
//第一种方式:通过构造函数,设置默认的session
ServletContextHandler context=new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server.setHandler(context);
//第二种方式：设置session
//Create the SessionHandler (wrapper) to handle the sessions
/*HashSessionManager manager = new HashSessionManager();
SessionHandler sessions = new SessionHandler(manager);
context.setHandler(sessions);*/
context.addServlet(new ServletHolder(new HelloServlet()), "/*");
server.start();
server.join();
}
}
class HelloServlet extends HttpServlet{
private static final long serialVersionUID = 1L;
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());
}
}
测试web是否启动成功：http://127.0.0.1:8080
web显示结果：

后面将通过例子，来逐步加深对《Jetty 的工作原理以及与 Tomcat 的比较》的理解。
