Jetty实践-Hello World
该程序摘自官网教程;
1、首先去Jetty官网,下载jetty-distribution-9.2.6.v20141205.zip,Jetty Jar包,解压到任意目录;
2、使用Eclipse新建一个Java Project,命名为helloworld-jetty;
3、选中工程,右键->properties->Java Build Path,得到下图:
4、按照上图所标,选中Add Library->User Library->User Libraries->New,得到下图,输入用户库名称,如jetty-lib-9.2.6;
选中刚添加的jetty-lib-9.2.6库,选择Add External JARs,将刚刚解压得到的jetty-distribution-9.2.6.v20141205\lib下的Jar包和jetty-distribution-9.2.6.v20141205\lib\jsp下的Jar包添加到该用户库下,点击OK,将jetty-lib-9.2.6库引入该工程。
5、创建HelloWorldJetty类,以下类摘自官网教程,只是改动了一下类名。
1 package org.example; 2 3 import java.io.IOException; 4 5 import javax.servlet.ServletException; 6 import javax.servlet.http.HttpServletRequest; 7 import javax.servlet.http.HttpServletResponse; 8 9 import org.eclipse.jetty.server.Request; 10 import org.eclipse.jetty.server.Server; 11 import org.eclipse.jetty.server.handler.AbstractHandler; 12 13 public class HelloWorldJetty extends AbstractHandler{ 14 15 public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response) 16 throws IOException, ServletException{ 17 18 response.setContentType("text/html;charset=utf-8"); 19 response.setStatus(HttpServletResponse.SC_OK); 20 baseRequest.setHandled(true); 21 response.getWriter().println("<h1>Hello World</h1>"); 22 } 23 24 public static void main(String[] args) throws Exception{ 25 Server server = new Server(8080); 26 server.setHandler(new HelloWorldJetty()); 27 28 server.start(); 29 server.join(); 30 } 31 }
6、右键运行该工程,Run As Java Application,使用浏览器访问http://localhost:8080/地址,可看到。
