《HTML5數(shù)據(jù)推送應(yīng)用開(kāi)發(fā)》源碼java版之一-----helloworld

1.新建servelet，，然后進(jìn)行編碼，最后編碼完后的源碼如下：

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, HttpServletResponse * response) */ protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub response.setContentType("text/event-stream");//設(shè)置事件流 response.setCharacterEncoding("UTF-8");//設(shè)置編碼 //獲取最新時(shí)間并返回 PrintWriter writer = response.getWriter(); String string = new Date().toString(); System.out.println(string); // send SSE writer.write("data: " + string + "\n\n"); try { //設(shè)置間隔時(shí)間 Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }

2.新建index.html文件，然后進(jìn)行編碼。編碼后的文件如下：
