Java我怎么知道会话的最后访问时间？
package org.nhooo.example.servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
public class SessionLastAccessTime extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
HttpSession session = request.getSession();
Date date = new Date(session.getLastAccessedTime());
PrintWriter writer = response.getWriter();
writer.println("Last accessed time: " + date);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
}该servlet将返回如下结果：
Last accessed time: Thu Jan 03 00:47:34 ICT 2008
