Java统计用户年/月/周/日网站访问量

一:准备工作,引入相关依赖：

二：运行效果图：

下一次访问

三：具体代码如下

 (1):CountObjectInfo.java

 package cn.csrc.base.count;

 import java.util.Date;

 public class CountObjectInfo {

     // 总访问量合计
     protected int totalCount = 0;
     // 日访问量
     protected int dayCount = 0;
     // 周访问量
     protected int weekCount = 0;
     // 月访问量
     protected int monthCount = 0;
     // 年访问量
     protected int yearCount = 0;

     // 临时访问量
     protected int tempCount = 0;

     protected Date date = new Date();

     public int getDayCount() {
         return dayCount;
     }

     public int getMonthCount() {
         return monthCount;
     }

     public int getTotalCount() {
         return totalCount;
     }

     public int getWeekCount() {
         return weekCount;
     }

     public int getYearCount() {
         return yearCount;
     }

     public void setDayCount(int i) {
         dayCount = i;
     }

     public void setMonthCount(int i) {
         monthCount = i;
     }

     public void setTotalCount(int i) {
         totalCount = i;
     }

     public void setWeekCount(int i) {
         weekCount = i;
     }

     public void setYearCount(int i) {
         yearCount = i;
     }

     public Date getDate() {
         return date;
     }

     public void setDate(Date date) {
         this.date = date;
     }

     public int getTempCount() {
         return tempCount;
     }

     public void setTempCount(int i) {
         tempCount = i;
     }

 }

至此就结束了!
