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;
} }
