Clickstream是一款用于跟踪网站用户点击路径的工具，通过监听用户会话并记录点击流，帮助分析用户行为。支持多种文件类型请求的跟踪，并能识别是否为机器人用户。

Clickstream 概述

一个用来跟踪正在你的站点上访问的用户所到达位置细节的工具。它允许你跟踪访问你的站点的“点击流”或者“传输路径”。请访问JIRA的更新日志来了解Clickstream最近的发展。

特性

• 当用户会话产生时，开始跟踪点击流。(通过一个监听器)
• 跟踪用户产生的每次点击信息。(通过一个过滤器)
• 当用户会话终止时，将完整的点击流记录到文件或者PrintStream中。
• 设法发现用户是不是机器人，并进行适当的过滤（目前可以检测252种机器人）

安装

把clickstream-1.0.2.jar and commons-logging.jar放到[web应用程序根目录]/WEB-INF/lib里，把下面的代码加到[web应用程序根目录]/WEB-INF/web.xml里面：


<filter>
      <filter-name>clickstream</filter-name>
      <filter-class>com.opensymphony.clickstream.ClickstreamFilter</filter-class>
</filter>

<filter-mapping>
      <filter-name>clickstream</filter-name>
      <url-pattern>*.jsp</url-pattern>
</filter-mapping>

<filter-mapping>
      <filter-name>clickstream</filter-name>
      <url-pattern>*.html</url-pattern>
</filter-mapping>

<listener>
<listener-class>com.opensymphony.clickstream.ClickstreamListener</listener-class>
</listener>

根据上面的配置，Clickstream会跟踪所有对jsp或者html文件的请求.无论什么时候，只要一个HttpSession失效了，对那个会话的完整点击流就会被记录。如果你想跟踪对其他类型的点击(例如.txt或者pdf文件)，只需要添加更多的filter-mapping就可以了。

下面是一个完整的web.xml的例子

 <?xml version="1.0" encoding="ISO-8859-1" ?> 
    <!DOCTYPE web-app (View Source for full doctype...)> 
    <web-app>
    <display-name>Opensymphony Clickstream Example</display-name> 
    <filter>
      <filter-name>clickstream</filter-name> 
      <filter-class>com.opensymphony.clickstream.ClickstreamFilter</filter-class> 
    </filter>
    <filter-mapping>
      <filter-name>clickstream</filter-name> 
      <url-pattern>/*</url-pattern> 
    </filter-mapping>

    <listener>
      <listener-class>com.opensymphony.clickstream.ClickstreamListener</listener-class>
    </listener>
    </web-app>

你可以利用clickstreams.jsp


<%@ page import="java.util.*,
                   com.opensymphony.clickstream.Clickstream" %>

<%
      Map clickstreams = (Map) application.getAttribute("clickstreams");

      String showbots = "false";
      if ("true".equalsIgnoreCase(request.getParameter("showbots")))
          showbots = "true";
      else if ("both".equalsIgnoreCase(request.getParameter("showbots")))
          showbots = "both";
%>
<html>
      <head>
          <title>All Clickstreams</title>
      </head>
    
      <body>
          <h1>All Clickstreams</h1>

          <a href="?showbots=false">No Bots</a> |
          <a href="?showbots=true">All Bots</a> |
          <a href="?showbots=both">Both</a>
        
          <p>        
          <% if (clickstreams.isEmpty()) { %>
            No clickstreams in progress.
          <% } else {
              synchronized(clickstreams) {
                  Iterator it = clickstreams.keySet().iterator();
                  int count = 0;
                  while (it.hasNext())
                  {
                      String key = (String)it.next();
                      Clickstream stream = (Clickstream)clickstreams.get(key);

                      if (showbots.equals("false") && stream.isBot())
                      {
                          continue;
                      }
                      else if (showbots.equals("true") && !stream.isBot())
                      {
                          continue;
                      }

                      count++;
                      try {
                  %>
                  <%= count %>. <a href="viewstream.jsp?sid=<%= key %>"><b><%= (stream.getHostname() != null &&  
!stream.getHostname().equals("") ? stream.getHostname() : "Stream") %></b></a> <font size="-1">[<%= stream.getStream().size()  
%> reqs]</font><br>
                  <%
                      }
                      catch (Exception e)
                      {
                  %>
                      An error occurred - <%= e %><br>
                  <%
                      }
                  }
              }
          }
          %>
          </p>
      </body>
</html>

和viewstream.jsp来显示系统当前的Clickstream活动。


<%@ page import="java.util.*,
                   com.opensymphony.clickstream.Clickstream,
                   com.opensymphony.clickstream.ClickstreamRequest" %>

<%
if (request.getParameter("sid") == null)
{
    response.sendRedirect("clickstreams.jsp");
    return;
}

Map clickstreams = (Map)application.getAttribute("clickstreams");

Clickstream stream = null;

if (clickstreams.get(request.getParameter("sid")) != null)
{
    stream = (Clickstream)clickstreams.get(request.getParameter("sid"));
}

if (stream == null)
{
    response.sendRedirect("clickstreams.jsp");
    return;
}
%>

<html>
      <head>
          <title>Clickstream for <%= stream.getHostname() %></title>
      </head>
    
      <body>
          <div align="right"><a href="clickstreams.jsp">All streams</a></div>

          <h1>Clickstream for <%= stream.getHostname() %></h1>

          <b>Initial Referrer</b>: <a href="<%= stream.getInitialReferrer() %>"><%= stream.getInitialReferrer() %></a><br>
          <b>Hostname</b>: <%= stream.getHostname() %><br>
          <b>Session ID</b>: <%= request.getParameter("sid") %><br>
          <b>Bot</b>: <%= stream.isBot() ? "Yes" : "No" %><br>
          <b>Stream Start</b>: <%= stream.getStart() %><br>
          <b>Last Request</b>: <%= stream.getLastRequest() %><br>
        
          <% long streamLength = stream.getLastRequest().getTime() - stream.getStart().getTime(); %>
          <b>Session Length</b>:
            <%= (streamLength > 3600000 ?
              " " + (streamLength / 3600000) + " hours" : "") +
            (streamLength > 60000 ?
              " " + ((streamLength / 60000) % 60) + " minutes" : "") +
            (streamLength > 1000 ?
              " " + ((streamLength / 1000) % 60) + " seconds" : "") %><br>
        
          <b># of Requests</b>: <%= stream.getStream().size() %>
        
          <p><b>Click stream</b>:</p>
        
          <table border="0" cellpadding="2">
          <%
          synchronized(stream) {
              Iterator clickstreamIt = stream.getStream().iterator();

              int count = 0;
              while (clickstreamIt.hasNext())
              {
                  count++;
                  String click = ((ClickstreamRequest)clickstreamIt.next()).toString();
              %>
              <tr><td><%= count %>:</td><td><a href="http://<%= click %>"><%= click %></a></td></tr>
              <%
              }
          }
          %>
          </table>
      </body>
</html>

配置

日志功能是非常基本的(你可以与log4j集成)。如果你需要更多更高级的日志功能，那就需要实现com.opensymphony.clickstream.logger.ClickstreamLogger接口并且提供任何你所希望的持久化方法。

默认情况下，Clickstream使用com.opensymphony.clickstream.logger.SimpleClickstreamLogger这个类来处理日志。这个logger只能向Jakarta的Commons Logging工具发送一个INFO日志声明，Commons Logging可以依次通知多个日志provider，包括log4j。

可以通过创建一个clickstream.xml配置文件并且把它放在你应用程序的类路径中（通常是[web应用程序根目录]/WEB-INF/classes）来改变这种默认的行为。配置文件可能是如下的形式：


<clickstream>
      <!-- there can only be one logger -->
      <logger class="com.opensymphony.clickstream.logger.SimpleClickstreamLogger"/>

      <!-- there can be zero or more bot-hosts -->
      <bot-host name="someBotHost"/>

      <!-- there can be zero or more bot-agents -->
      <bot-agent name="someBotAgent"/>
</clickstream>
