定时统计页面点击量

1.在web 应用启动时，开启一个servlet.servlet开一线程独立跑同步到数据库的操作。

2.添加一个filter ,过滤所有的url 把符合需要统计的url 的统计数加1.filter 里用静态变量来保存统计数.

代码如下:

1.ClickCount.java

package com.click.ClickCount; import java.text.SimpleDateFormat; import java.util.Date; import com.click.filter.ClickFilter; public class ClickCount implements Runnable { //private final static int DELAY = 1000 * 60 * 60; // 1小时 private final static int DELAY = 1000 * 3; // 1小时 private int tmp = 0; /** * */ public ClickCount() { System.out.println("***************************************"); System.out.println("计算EC点击量线程已经启动...."); System.out.println("首次插入数据在启动服务的第一个整点前大约30秒!"); System.out.println("随后每隔" + (DELAY / 1000) + "秒插入一次数据"); } /** * 同步点击量线程 */ public void run() { while (true) { try { if (tmp == 0) { //首次进入线程,计算距离下个整点的时间 int remaintime = this.remainTime(); Thread.sleep(remaintime); this.addSysClickInfo(); } tmp++; Thread.sleep(DELAY); this.addSysClickInfo(); } catch (Exception e) { } } } /** * 计算当前时间距离下个整点前30秒的时间 返回毫秒 * @return int */ private int remainTime() { Date date = new Date(); String min = new SimpleDateFormat("mm").format(date); String sec = new SimpleDateFormat("ss").format(date); //取整点前30秒的数据,方便计算及处理 int remaintime = 1000*3;//((60 - new Integer(min).intValue()) * 60 - new Integer(sec).intValue() - 30) * 1000; System.out.println("当前时间:" + new SimpleDateFormat("HH:mm:ss").format(date)); System.out.println("距离下个整点的时间为" + (remaintime / 1000) + "秒!"); return remaintime; } /** * 同步平台点击量到数据库 */ private void addSysClickInfo() { Date date = new Date(); String year = new SimpleDateFormat("yyyy").format(date); String month = new SimpleDateFormat("MM").format(date); String day = new SimpleDateFormat("dd").format(date); String hour = new SimpleDateFormat("HH").format(date); System.out.println("同步平台点击量到数据库"+ClickFilter.count); } }

2.ClickFilter.java

package com.click.filter; import java.io.IOException; import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class ClickFilter implements Filter { public static int count; public void destroy() { } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest req = (HttpServletRequest) request; HttpServletResponse res = (HttpServletResponse) response; if (isCountClick(req)) { count++; //System.out.println("EC计算点击的链接----->"+req.getRequestURI()); //System.out.println("EC计算点击量----->"+times); } } /** * 可计入点击量的请求 * @param req * @return */ private boolean isCountClick(HttpServletRequest req) { String uri = req.getRequestURI(); if (uri.indexOf(".do") != -1 || uri.indexOf(".jsp") != -1) { return true; } return false; } public void init(FilterConfig arg0) throws ServletException { } }

 

3.ClickTimeServlet.java

package com.click.servlet; import javax.servlet.ServletException; import com.click.ClickCount.ClickCount; /** * Servlet implementation class for Servlet: ClickTimeServlet * */ public class ClickTimeServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { static final long serialVersionUID = 1L; public ClickTimeServlet() { super(); } public void init() throws ServletException { new Thread(new ClickCount(), "CountClick").start(); super.init(); } }

 

4.web.xml

<filter> <filter-name>TimeClickFilter</filter-name> <filter-class>com.click.filter.ClickFilter</filter-class> </filter> <filter-mapping> <filter-name>TimeClickFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <description></description> <display-name>ClickTimeServlet</display-name> <servlet-name>ClickTimeServlet</servlet-name> <servlet-class>com.click.servlet.ClickTimeServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet>
