网站流量统计，java+jsp 获取访客浏览器，真实ip，操作系统，来源

公司最近在做官网，需要做流量统计，发现网上关于这一块的东西比较杂乱。整理了一下，以后备用

--------------------------------------------------------------------------------------------------------------------------------

采用servlet的filter获取request对象，以获取访客信息

public class StatFilter
    implements Filter {
    public StatFilter() {
    }

    public void init(FilterConfig filtercfg) throws javax.servlet.
        ServletException {
    }

    public void doFilter(ServletRequest request,
                         ServletResponse response,
                         FilterChain filterchain) throws java.io.IOException,
        javax.servlet.ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
       
        HttpSession session = httpRequest.getSession(true);
       
        if (session.getAttribute("isRecorded") == null) {
            //如果本次用户访问还没有记录，就记录本次用户信息，并保存到数据库中
            session.setAttribute("isRecorded", Boolean.TRUE);
            //在session对象中保存一个变量"isRecorded"，并赋值
            String ip = getIp(httpRequest);//用户ip
            String browser = getBrowser(httpRequest);//用户使用的浏览器
            String os = getSysInfo(httpRequest);//用户使用系统
            String source = httpRequest.getHeader("Referer");//访问来源
            String url = httpRequest.getRequestURI();//用户当前访问路径
    
            if (browser == null) {
                browser = "未知";
                //如果读取的浏览器名为空，则赋值为“未知”
            }
            if (os == null) {
                os = "未知";
                //如果读取的操作系统名为空，则赋值为“未知”
            }
            try {
                System.out.println("ip:"+ip);
                System.out.println("os:"+os.trim());
                System.out.println("browser:"+browser.trim());
                System.out.println("source:"+source);
                System.out.println("url:"+url);
            //    StatHandle.insert(ip, os.trim(), browser.trim());
                //调用业务逻辑，将用户数据插入到数据库中
            }
            catch (Exception es) {
                es.printStackTrace();
                //在输入日志中打印异常信息
            }
        }
        filterchain.doFilter(request, response);
        //调用下一个过滤器或者直接调用JSP
    }

今天在实现的过程中，找出来一点问题，继续贴在末尾吧。上面是将代码写在了filter里，有一点不合适，因为在filter中的代码，只有在创建servlet容器的时候才会执行一次filter，此后则不再执行，我们要记录多个页面的访问情况，最好将代码嵌在jsp页面的初始化。这样则不受影响了
