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() %
