Servlet中让线程沉睡实例源码



Servlet中让线程沉睡实例源码，servlet线程的应用实例：

Servlet_Thread.java源码：

package com.cn.thread;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Servlet_Thread extends HttpServlet {
private String username;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

response.setContentType(“text/html”);
//设置页面编码方式，支持中文显示
response.setCharacterEncoding(“utf-8″);
PrintWriter out = response.getWriter();
//用request中的getParameter方法获取username参数
username = request.getParameter(“username”);
try {
//调用sleep方法，让线程沉睡15秒钟
Thread.sleep(15000);
} catch (InterruptedException e) {}
out.println(“<!DOCTYPE HTML PUBLIC \”-//W3C//DTD HTML 4.01 Transitional//EN\”>”);
out.println(“<HTML>”);
out.println(” <HEAD><TITLE>A Servlet</TITLE></HEAD>”);
out.println(” <BODY>”);
out.println(” 您好! ” + username + “. 您使用了 GET 方式提交数据”);
out.println(” </BODY>”);
out.println(“</HTML>”);
out.flush();
out.close();


}

// doPost方法，该方法在本例子中没有被调用
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType(“text/html”);
//设置页面编码方式，支持中文显示
response.setCharacterEncoding(“utf-8″);
PrintWriter out = response.getWriter();
//用request中的getParameter方法获取username参数
username = request.getParameter(“username”);
try {
//调用sleep方法，让线程沉睡15秒钟
Thread.sleep(15000);
} catch (InterruptedException e) {}
out.println(“<!DOCTYPE HTML PUBLIC \”-//W3C//DTD HTML 4.01 Transitional//EN\”>”);
out.println(“<HTML>”);
out.println(” <HEAD><TITLE>A Servlet</TITLE></HEAD>”);
out.println(” <BODY>”);
out.println(” 您好! ” + username + “. 您使用了 GET 方式提交数据”);
out.println(” </BODY>”);
out.println(“</HTML>”);
out.flush();
out.close();
}
}
