1.cookie对象：
cookie是一种会话技术,它用于将会话过程中的数据保存到用户的浏览器中,从而使浏览器和服务器可以更好的地进行数据交互;
创建Serlet:
创建一个chapter05项目,创建一个自己喜欢的包,在该包中编写一个为LastAccessSerclet的Servlet类,实现获取Cookiie信息并将当前时间cookie值发送给客户端;
代码如下:
package chapter05.access;
import java.io.IOException;
import java.util.Date;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import jdk.javadoc.doclet.Reporter;
@WebServlet("/LastAccessServlet")
public class LastAccessServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public LastAccessServlet() {
// TODO Auto-generated constructor stub
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.setContentType("text/html;charset=utf-8");
cookie[ ] cookies=request.getcookies();
String lastTime=null;
for (int i = 0; cookies != null&&i
