网站访问量统计java代码怎样写？

DIV class="h"

%-- 记录网站访问次数 --%

%

Integer counter = (Integer)application.getAttribute("counter"); //先从application里面获取计数器的key的值

if(counter==null){

//如果该值为null，说明第一次访问

application.setAttribute("counter",1);

counter=(Integer)application.getAttribute("counter");

}else {

//如果该值不为空，取出来进行累加

int i = counter.intValue();

i++;

application.setAttribute("counter",i);//累加后再放进去

}

%

% User user =(User)session.getAttribute("users"); %

%="欢迎"+user.getName() % |您是第%=counter.intValue()%位访客

/DIV

谢谢~

java每周后台系统自动统计一次报表显示在jsp上面怎么做？

根据你所谓的结束日期 往前推一周的时间算出开始日期，具体的代码懒得写了 你查下Calendar类的用法 里面有这个推前一周的写法 希望能帮到你

java如何统计网站访问量？

步骤一、建一个表，表名任意，这里取名为：visitorcounter，表的结构如下所示：

+-------+------------------+------+-----+------------+----------------+

| Field | Type | Null | Key | Default | Extra |

+-------+------------------+------+-----+------------+----------------+

| id | int(11) unsigned | NO | PRI | NULL | auto_increment |

| vdate | date | NO | | 2000-01-01 | |

| vnum | int(11) | NO | | 0 | |

+-------+------------------+------+-----+------------+----------------+

步骤二、建立一个java类，名字也为：visitorcounter，类的内容如下：

package com.hdzx.pub;

import java.sql.ResultSet;

import java.text.SimpleDateFormat;

import java.util.Date;

public class VisitorCounter {

private final static String TABLE_NAME = "visitorcounter";

private static String today = null;

private static long today_num = 0;

private static long total_num = 0;

//加载访问量

public static void loadNum(){

if(total_num1)

loadTotalNum();

if(today_num1)

loadToadyNum();

}

//加载今日访问量

private static void loadToadyNum() {

// TODO Auto-generated method stub

DBConnect db = null;

ResultSet rs = null;

if(today==null)

today = getTodayDate();

String sql = "select vnum from "+TABLE_NAME+" where vdate='"+today+"'";

try {

db = new DBConnect();

rs = db.executeQuery(sql);

if(rs.next()){

today_num = rs.getLong("vnum");

}

else

{

sql = "insert into "+TABLE_NAME+"(vdate,vnum) values('"+today+"',0)";

db.executeUpdate(sql);

today_num = 0;

}

} catch (Exception e) {

// TODO: handle exception

today_num = 0;

System.out.println("com.hdzx.pub~VisitorCounter.incTotalCounter:获得访问人数");

}

}

//加载总访问量

private static void loadTotalNum() {

// TODO Auto-generated method stub

// TODO Auto-generated method stub

DBConnect db = null;

ResultSet rs = null;

if(today==null)

today = getTodayDate();

String sql = "select vnum from "+TABLE_NAME+" where id=1";

try {

db = new DBConnect();

rs = db.executeQuery(sql);

if(rs.next()){

total_num = rs.getLong("vnum");

}

else

{

total_num = 0;

}

} catch (Exception e) {

// TODO: handle exception

total_num = 0;

System.out.println("com.hdzx.pub~VisitorCounter.incTotalCounter:获得访问人数");

}

}

//增加总的访问量

private static int incTotalCounter(){

int k = 0;

DBConnect db = null;

loadNum();

total_num = total_num+1;

String sql = "update "+TABLE_NAME+" set vnum="+total_num+" where id=1";

try {

db = new DBConnect();

k = db.executeUpdate(sql);

} catch (Exception e) {

// TODO: handle exception

System.out.println("com.hdzx.pub~VisitorCounter.incTotalCounter:增加访问人数");

}

return k;

}

//增加今日的访问量

public static int incTodayCounter(){

int k = 0;

DBConnect db = null;

String sql = null;

loadNum();

today_num += 1;

sql = "update "+TABLE_NAME+" set vnum="+today_num+" where vdate='"+today+"'";

try {

db = new DBConnect();

k = db.executeUpdate(sql);

if(k 0)

incTotalCounter();

} catch (Exception e) {

// TODO: handle exception

System.out.println("com.hdzx.pub~VisitorCounter.incTotalCounter:增加访问人数");

}

return k;

}

//获得今天的日期

private static String getTodayDate(){

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

return sdf.format(new Date());

}

///获得今日访问量

public static long getTodayNum(){

loadNum();

return today_num;

}

//获得总的访问量

public static long getTotalNum(){

loadNum();

return total_num;

}

}

步骤三、经过以上的步骤后，在页面中加入以下的代码，就可以实现网站访问量的统计工作：

if(session.isNew())

{

VisitorCounter.incTodayCounter();

}

%

今日访问量：%=VisitorCounter.getTodayNum() %br/

总的访问量: %=VisitorCounter.getTotalNum() %
