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
1 package cn.csrc.base.count; 2 3 import java.util.Date; 4 5 public class CountObjectInfo { 6 7 // 总访问量合计 8 protected int totalCount = 0; 9 // 日访问量 10 protected int dayCount = 0; 11 // 周访问量 12 protected int weekCount = 0; 13 // 月访问量 14 protected int monthCount = 0; 15 // 年访问量 16 protected int yearCount = 0; 17 18 // 临时访问量 19 protected int tempCount = 0; 20 21 protected Date date = new Date(); 22 23 public int getDayCount() { 24 return dayCount; 25 } 26 27 public int getMonthCount() { 28 return monthCount; 29 } 30 31 public int getTotalCount() { 32 return totalCount; 33 } 34 35 public int getWeekCount() { 36 return weekCount; 37 } 38 39 public int getYearCount() { 40 return yearCount; 41 } 42 43 public void setDayCount(int i) { 44 dayCount = i; 45 } 46 47 public void setMonthCount(int i) { 48 monthCount = i; 49 } 50 51 public void setTotalCount(int i) { 52 totalCount = i; 53 } 54 55 public void setWeekCount(int i) { 56 weekCount = i; 57 } 58 59 public void setYearCount(int i) { 60 yearCount = i; 61 } 62 63 public Date getDate() { 64 return date; 65 } 66 67 public void setDate(Date date) { 68 this.date = date; 69 } 70 71 public int getTempCount() { 72 return tempCount; 73 } 74 75 public void setTempCount(int i) { 76 tempCount = i; 77 } 78 79 }

(4):xmlcount.xml文件的初始内容如下： (放在WEB_INF目录下)
<?xml version="1.0" encoding="UTF-8"?> <xml-body> </xml-body>
至此就结束了!
