1. Create a new servelet, then encode it, and the source code after the last encoding is as follows:
Package Com.heetian.servlet;import Java.io.ioexception;import Java.io.printwriter;import java.util.Date;import Javax.servlet.servletexception;import Javax.servlet.annotation.webservlet;import Javax.servlet.http.HttpServlet; Import Javax.servlet.http.httpservletrequest;import javax.servlet.http.httpservletresponse;/** * servlet Implementation class Sseechoservlet */@WebServlet ("/sseechoservlet") public class Sseechoservlet extends HttpServlet { Private static final Long Serialversionuid = 1l;/** * @see httpservlet#doget (httpservletrequest request, HTTPSERVLETRESPO NSE * response) */protected void doget (httpservletrequest request,httpservletresponse response) throws Servletexcepti On, IOException {//TODO auto-generated method Stubresponse.setcontenttype ("Text/event-stream");// Set event Stream response.setcharacterencoding ("UTF-8");//Set encode//Get latest time and return printwriter writer = Response.getwriter (); String string = new Date (). toString (); System.out.println (string);//Send Ssewriter.write ("Data: "+ string +" \ n "); try {//Set interval time thread.sleep (1000);} catch (Interruptedexception e) {//TODO auto-generated catch Blocke.printstacktrace ();}}}
2. Create a new index.html file and encode it. The encoded files are as follows:
<!doctype html>3. After running, you can see the output time in the browser. The effect is as follows:
Initialize ... Sun Nov 13:56:22 CST 2014Sun Nov 13:56:27 CST 2014Sun Nov 13:56:31 CST 2014Sun Nov 13:56:35 CST 2014Sun Nov 23 13:56:39 CST 2014Sun Nov 13:56:43 CST 2014Sun Nov 13:56:47 CST 2014Sun Nov 13:56:51 CST 2014Sun Nov 23 13:56:55 CST 2014Sun Nov 13:56:59 CST 2014Sun Nov 13:57:03 CST 2014.
